RHEL5(CentOS)下nginx+php+mysql+tomcat+memchached配置全過程

一、準(zhǔn)備工作：
SSH,telnet終端中文顯示亂碼解決辦法
vi /etc/sysconfig/i18n
將內(nèi)容改為
LANG="zh_CN.GB18030"
LANGUAGE="zh_CN.GB18030:zh_CN.GB2312:zh_CN"
SUPPORTED="zh_CN.GB18030:zh_CN:zh:en_US.UTF-8:en_US:en"
SYSFONT="lat0-sun16"

二、安裝PHP 5.2.10（FastCGI模式）
1、編譯安裝PHP 5.2.10所需的支持庫：
tar zxvf libiconv-1.13.tar.gz
cd libiconv-1.13/
./configure --prefix=/usr/local
make
make install
cd ../

tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8/
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd http://www.cnblogs.com/

tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install
cd ../

ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1

tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../

2、編譯安裝MySQL 5.1.38
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.1.38.tar.gz
cd mysql-5.1.38/
./configure --prefix=/usr/local/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=innobase
make && make install
chmod +w /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql
cd ../

附：以下為附加步驟，如果你想在這臺服務(wù)器上運行MySQL數(shù)據(jù)庫，則執(zhí)行以下兩步。如果你只是希望讓PHP支持MySQL擴展庫，能夠連接其他服務(wù)器上的MySQL數(shù)據(jù)庫，那么，以下兩步無需執(zhí)行。

①、創(chuàng)建MySQL數(shù)據(jù)庫存放目錄
mkdir -p /data/mysql/data/
chown -R mysql:mysql /data/mysql/

②、以mysql用戶帳號的身份建立數(shù)據(jù)表：
/usr/local/mysql/bin/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql/data --user=mysql

③、創(chuàng)建my.cnf配置文件：
vi /data/mysql/my.cnf
輸入以下內(nèi)容：
引用
[client]
default-character-set = utf8
port??? = 3306
socket? = /tmp/mysql.sock

[mysql]
prompt="(\u:www.xxx.com:)[\d]> "
no-auto-rehash

[mysqld]
#default-character-set = utf8
lower_case_table_names=1
user??? = mysql
port??? = 3306
socket? = /tmp/mysql.sock
basedir = /usr/local/mysql
datadir = /data/mysql/data
open_files_limit??? = 10240
back_log = 600
max_connections = 3000
max_connect_errors = 6000
table_cache = 614
external-locking = FALSE
max_allowed_packet = 32M
sort_buffer_size = 2M
join_buffer_size = 2M
thread_cache_size = 300
thread_concurrency = 8
query_cache_size = 32M
query_cache_limit = 2M
query_cache_min_res_unit = 2k
default-storage-engine = MyISAM
default_table_type = MyISAM
thread_stack = 192K
transaction_isolation = READ-COMMITTED
tmp_table_size = 246M
max_heap_table_size = 246M
long_query_time = 1
log_long_format
log-bin = /data/mysql/binlog
binlog_cache_size = 4M
binlog_format = MIXED
max_binlog_cache_size = 8M
max_binlog_size = 512M
expire_logs_days = 7
key_buffer_size = 256M
read_buffer_size = 1M
read_rnd_buffer_size = 16M
bulk_insert_buffer_size = 64M
myisam_sort_buffer_size = 128M
myisam_max_sort_file_size = 10G
myisam_max_extra_sort_file_size = 10G
myisam_repair_threads = 1
myisam_recover

skip-name-resolve
master-connect-retry = 10
slave-skip-errors = 1032,1062,126,1114,1146,1048,1396

server-id = 1

innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 2048M
innodb_data_file_path = ibdata1:1024M:autoextend
innodb_file_io_threads = 4
innodb_thread_concurrency = 8
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 16M
innodb_log_file_size = 128M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 90
innodb_lock_wait_timeout = 120
innodb_file_per_table = 0
[mysqldump]
quick
max_allowed_packet = 32M

直接殺掉mysql進(jìn)程：killall -TERM mysqld

④、創(chuàng)建管理MySQL數(shù)據(jù)庫的shell腳本：
vi /data/mysql/mysql

#!/bin/sh

mysql_port=3306
mysql_username="root"
mysql_password="xxx_dba"

function_start_mysql()
{
??? printf "Starting MySQL...\n"
??? /bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysql/my.cnf 2>&1 > /dev/null &
}

function_stop_mysql()
{
??? printf "Stoping MySQL...\n"
??? /usr/local/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown
}

function_restart_mysql()
{
??? printf "Restarting MySQL...\n"
??? function_stop_mysql
??? sleep 5
??? function_start_mysql
}

function_kill_mysql()
{
??? kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')
??? kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')
}

if [ "$1" = "start" ]; then
??? function_start_mysql
elif [ "$1" = "stop" ]; then
??? function_stop_mysql
elif [ "$1" = "restart" ]; then
function_restart_mysql
elif [ "$1" = "kill" ]; then
function_kill_mysql
else
??? printf "Usage: /data/mysql/mysql {start|stop|restart|kill}\n"
fi

⑤、賦予shell腳本可執(zhí)行權(quán)限：
chmod +x /data/mysql/mysql

⑥、啟動MySQL：
/data/mysql/mysql start

⑦、通過命令行登錄管理MySQL服務(wù)器（提示輸入密碼時直接回車）：
/usr/local/mysql/bin/mysql -u root -p -S /tmp/mysql.sock

若出現(xiàn)問題：
ps -aux | grep mysql
mysql???? 1382 0.0 0.2 5544 1376 pts/0??? S??? 17:34?? 0:00 bash
mysql???? 1475 0.0 0.2 5552 1388 pts/0??? S??? 17:38?? 0:00 bash
# chown -R mysql:mysql /usr/local/mysql/

⑧、輸入以下SQL語句，創(chuàng)建一個具有root權(quán)限的用戶（admin）和密碼（12345678）：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'xxx_dba';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1' IDENTIFIED BY 'xxx_dba';

⑨、（可選）停止MySQL：
/data/mysql/mysql stop

3、編譯安裝PHP（FastCGI模式）
tar zxvf php-5.2.10.tar.gz
gzip -cd php-5.2.10-fpm-0.5.11.diff.gz | patch -d php-5.2.10 -p1
cd php-5.2.10/
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap --without-pear
make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-dist /usr/local/php/etc/php.ini
cd ../
curl http://pear.php.net/go-pear | /usr/local/php/bin/php

4、編譯安裝PHP5擴展模塊
tar zxvf memcache-2.2.5.tgz
cd memcache-2.2.5/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

tar jxvf eaccelerator-0.9.5.3.tar.bz2
cd eaccelerator-0.9.5.3/
/usr/local/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql
make
make install
cd ../

tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make
make install
cd ../

tar zxvf imagick-2.2.2.tgz
cd imagick-2.2.2/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

5、修改php.ini文件
手工修改：查找/usr/local/php/etc/php.ini中的extension_dir = "./"
修改為extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
并在此行后增加以下幾行，然后保存：
　　extension = "memcache.so"
　　extension = "pdo_mysql.so"
　　extension = "imagick.so"

再查找output_buffering = Off
修改為output_buffering = On

自動修改：若嫌手工修改麻煩，可執(zhí)行以下shell命令，自動完成對php.ini文件的修改：
sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /usr/local/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/php/etc/php.ini
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/php/etc/php.ini

6、配置eAccelerator加速PHP：
mkdir -p /usr/local/eaccelerator_cache
vi /usr/local/php/etc/php.ini

按shift+g鍵跳到配置文件的最末尾，加上以下配置信息：

[eaccelerator]
zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/usr/local/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

7、創(chuàng)建www用戶和組，以及虛擬主機使用的目錄：
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data/htdocs/group
chmod +w /data/htdocs/group
chown -R www:www /data/htdocs/group

8、創(chuàng)建php-fpm配置文件（php-fpm是為PHP打的一個FastCGI管理補丁，可以平滑變更php.ini配置而無需重啟php-cgi）：
在/usr/local/php/etc/目錄中創(chuàng)建php-fpm.conf文件：
rm -f /usr/local/php/etc/php-fpm.conf
vi /usr/local/php/etc/php-fpm.conf

輸 入以下內(nèi)容（如果您安裝 Nginx + PHP 用于程序調(diào)試，請將以下的<value name="display_errors">0</value>改為<value name="display_errors">1</value>，以便顯示PHP錯誤信息，否則，Nginx 會報狀態(tài)為500的空白錯誤頁）：

</configuration>

9、啟動php-cgi進(jìn)程，監(jiān)聽127.0.0.1的9000端口，進(jìn)程數(shù)為200（如果服務(wù)器內(nèi)存小于3GB，可以只開啟64個進(jìn)程），用戶為www：
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
注：/usr/local/php/sbin/php-fpm還有其他參數(shù)，包括：start|stop|quit|restart|reload|logrotate，修改php.ini后不重啟php-cgi，重新加載配置文件使用reload。

注 意：此處啟動時遇到了麻煩， 啟動警告：libgomp.so.1: shared object cannot be dlopen()ed in Unknown on line 0，經(jīng)過百度，有人說是gcc版本太低，我可能了下我的GCC版本是4.1.1 20070105。
升級GCC

三、安裝Nginx 0.8.15
1、安裝Nginx所需的pcre庫：
tar zxvf pcre-7.9.tar.gz
cd pcre-7.9/
./configure
make && make install
cd ../

2、安裝Nginx
tar zxvf nginx-0.8.15.tar.gz

make && make install
cd ../

3、創(chuàng)建Nginx日志目錄
mkdir -p /data/logs
chmod +w /data/logs
chown -R www:www /data/logs

4、創(chuàng)建Nginx配置文件

5、啟動Nginx
ulimit -SHn 65535
/usr/local/nginx/sbin/nginx

四、配置開機自動啟動Nginx + PHP
vi /etc/rc.local

在末尾增加以下內(nèi)容：
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
/usr/local/nginx/sbin/nginx

五、優(yōu)化Linux內(nèi)核參數(shù)

使配置立即生效：
/sbin/sysctl -p

六、在不停止Nginx服務(wù)的情況下平滑變更Nginx配置
1、修改/usr/local/nginx/conf/nginx.conf配置文件后，請執(zhí)行以下命令檢查配置文件是否正確：
/usr/local/nginx/sbin/nginx -t

如果屏幕顯示以下兩行信息，說明配置文件正確：
　　the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
　　the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully

2、這時，輸入以下命令查看Nginx主進(jìn)程號：
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'

屏幕顯示的即為Nginx主進(jìn)程號，例如：
　　6302
這時，執(zhí)行以下命令即可使修改過的Nginx配置文件生效：
kill -HUP 6302

或者無需這么麻煩，找到Nginx的Pid文件：
kill -HUP `cat /usr/local/nginx/nginx.pid`

0.8以后的產(chǎn)品
/usr/local/nginx/sbin/nginx -s reload

七、編寫每天定時切割Nginx日志的腳本
1、創(chuàng)建腳本/usr/local/nginx/sbin/cut_nginx_log.sh
vi /usr/local/nginx/sbin/cut_nginx_log.sh

輸入以下內(nèi)容：
#!/bin/bash
# This script run at 00:00

# The Nginx logs path
logs_path="/usr/local/nginx/logs/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/nginx/nginx.pid`


2、設(shè)置crontab，每天凌晨00:00切割nginx訪問日志
crontab -e

輸入以下內(nèi)容：

00 00 * * * /bin/bash? /usr/local/nginx/sbin/cut_nginx_log.sh


八、安裝JDK+TOMCAT
1、安裝JDK
#chmod +X jdk-6u18-ea-bin-b05-linux-i586-18_nov_2009.bin
# ./jdk-6u18-ea-bin-b05-linux-i586-18_nov_2009.bin
# mv jdk1.6.0.18 /usr/local/jdk
2、配置環(huán)境變量
# vi /etc/profile
按shift+g，將下面這段文字加到結(jié)尾
export JAVA_HOME=/usr/local/jdk
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$CLASSPATH
export PATH=$PATH:$JAVA_HOME/jre/bin

export CATALINA_HOME=/usr/local/tomcat
wq退出
3、讓配置立即啟用
source /etc/profile

九、安裝TOMCAT
# tar zxvf apache-tomcat-6.0.26.tar.gz
# mv apache-tomcat-6.0.26 /usr/local/tomcat

十：配置nginx.conf：
vi /usr/local/nginx/conf/nginx.conf

user? www www;

worker_processes 8;

error_log? /data/logs/nginx_error.log? crit;

pid??????? /usr/local/nginx/nginx.pid;

}

十一、安裝memcached
首先安裝 memcache 的時候缺少 libevent。還是先安裝好 libevent， 下載libevent：http://www.monkey.org/~provos/libevent-1.4.9-stable.tar.gz。

[root@master chenlb]# wget http://www.danga.com/memcached/dist/memcached-1.2.6.tar.gz
[root@master chenlb]# tar zxvf memcached-1.2.6.tar.gz
[root@master chenlb]# cd memcached-1.2.6
[root@master memcached-1.2.6]# ./configure --prefix=/usr/local/memcache --with-libevent=/usr/local
[root@master memcached-1.2.6]# make
[root@master memcached-1.2.6]# make install

接著運行：

?? 1. [root@master memcached-1.2.6]# /usr/local/memcached/bin/memcached -d -m 10 -p 11211 -u root ?
?? 2. /usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory ?

[root@master memcached-1.2.6]# /usr/local/memcached/bin/memcached -d -m 10 -p 11211 -u root
/usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory

報錯說：libevent-1.4.so.2 不在公共文件里。郁悶，然后打到 芽雨快跑 的 blog。解決方法是鏈接一下。

?? 1. [root@master memcached-1.2.6]# ln -s /usr/local/lib/libevent-1.4.so.2 /usr/lib/libevent-1.4.so.2 ?
?? 2. [root@master memcached-1.2.6]# /usr/local/memcached/bin/memcached -d -m 10 -p 11211 -u root ?

十二、創(chuàng)建數(shù)據(jù)庫用戶并賦權(quán)：
GRANT SELECT , INSERT , UPDATE , DELETE , CREATE , DROP , INDEX , ALTER , CREATE TEMPORARY TABLES , CREATE VIEW , SHOW VIEW , CREATE FUNCTION,CREATE PROCDURE, CREATE ROUTINE, ALTER ROUTINE, EXECUTE ON dotayo_db.* TO 'dotayo_db'@'192.168.1.%' IDENTIFIED BY 'dotayo_db';

十三、從開發(fā)機復(fù)制數(shù)據(jù)庫實例到測試機，若有函數(shù)或存儲過程，需設(shè)置：
mysql> SET GLOBAL log_bin_trust_function_creators = 1;
Query OK, 0 rows affected (0.00 sec)

已管理員賬號登陸SQLyog，連接開發(fā)數(shù)據(jù)庫與測試數(shù)據(jù)庫，copy完成，數(shù)據(jù)庫搭建完成。

十四：啟動tomcat，OutOfMemoryError: PermGen space
解決辦法：
以下給出2G內(nèi)存環(huán)境下java jvm 的參數(shù)設(shè)置參考：
vi /usr/local/tomcat/bin/catalina.sh
在“echo "Using CATALINA_BASE:?? $CATALINA_BASE"”上面加入以下行：
JAVA_OPTS="-server -Xms800m -Xmx800m? -XX:PermSize=128M -XX:MaxNewSize=512m -XX:MaxPermSize=256m -Djava.awt.headless=true "

重啟tomcat

十五、配置iptables:
#vi /etc/sysconfig/iptables
文件內(nèi)容
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]

COMMIT

至此，服務(wù)器配置全部完成，以上配置參考了一些牛人的文檔！

注意事項：
壓縮解壓縮文件
用戶用mydir目錄中最近被修改或添加的文件來對myarch.tar文件進(jìn)行更新。

#tar uf myarch.tar mydir
#tar zxvf myarch.tar

如果你安裝了某些庫，比如在安裝gtk -2.4.13時它會需要glib-2.0 >= 2.4.0,辛苦的安裝好glib后
沒有指定 --prefix=/usr 這樣glib庫就裝到了/usr/local下，而又沒有在/etc/ld.so.conf中添加/usr/local/lib
這個搜索路徑，所以編譯gtk -2.4.13就會出錯了
