測試系統：CentOS6.2 64BIT

mysql 更新為5.5.21

php等部分軟件升級

一、同步系統時間

ntp.api.bz?是一組NTP服務器集群，目前有6臺服務器，位于上海電信。這項服務是 api.bz 繼?http://sms.api.bz?移動飛信免費短信發送接口之后的第二項免費 API 服務。

ntpdate ntp.api.bz

設置每小時同步一次時間

crontab -e

添加：

* */1 * * * ntpdate ntp.api.bz >> /var/log/ntpdate.log

二、配置網易YUM源(可選)

首先備份/etc/yum.repos.d/CentOS-Base.repo????mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

下載對應版本repo文件, 放入/etc/yum.repos.d/(操作前請做好相應備份)

運行yum makecache生成緩存

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

mkdir -p /data0/software

cp CentOS6-Base-163.repo /etc/yum.repos.d/

yum makecache

三、獲取開源程序

sudo -s

LANG=C

yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers

軟件存放目錄

mkdir -p /data0/software

-DINSTALL_DATADIR=/data0/mysql/data //數據庫存放目錄

-DDEFAULT_CHARSET=utf8 //使用utf8字符

-DDEFAULT_COLLATION=utf8_general_ci? //校驗字符

-DEXTRA_CHARSETS=all? //安裝所有擴展字符集

-DWITH_SSL=system //使用SSL加密

-DWITH_EMBEDDED_SERVER=1 //編譯成embedded mysql library

-DENABLED_LOCAL_INFILE=1 //允許從本地導入數據

-DWITH_MYISAM_STORAGE_ENGINE=1 //安裝myisam引擎

配置mysql

mkdir -p?/data0/mysql/data

groupadd mysql

useradd -g mysql mysql

chown -R mysql:mysql /data0/mysql/data

cp support-files/my-medium.cnf /etc/my.cnf

vi /etc/my.cnf

在my.cnf中增加用戶名及數據目錄

在[mysqld]下面增加:

user=mysql

datadir=/data0/mysql/data

開啟事件調度(可選)

在?[mysqld]?的下面加入如下行

event_scheduler=1

安裝mysql初使化系統表其數據

cd /usr/local/webserver/mysql

./scripts/mysql_install_db --user=mysql

配置mysqld服務，并使其開機自運行

cp support-files/mysql.server /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld

chkconfig --add mysqld

chkconfig mysqld --level 3 on

修改/etc/init.d/mysqld相關配置

vi /etc/init.d/mysqld

將datadir指定為/data0/mysql/data

將basedir指定為/usr/local/webserver/mysql

basedir=/usr/local/webserver/mysql

datadir=/data0/mysql/data

mysqld_pid_file_path=/data/mysql/data/mysql.pid(可選)

啟動mysql及指定mysql root密碼

service mysqld start

./bin/mysqladmin -u root password 'admin'

將mysql相關命令加到用戶PATH中去

vi ~/.bash_profile

將PATH改為：

PATH=$PATH:$HOME/bin:/usr/local/webserver/mysql/bin

使其生效：

. ~/.bash_profile

啟動，停止和重啟mysql命令

service mysqld start

service mysqld stop

service mysqld restart

登錄到mysql

5、修改php.ini文件

手工修改：查找/usr/local/webserver/php/etc/php.ini中的extension_dir = "./"

修改為extension_dir = "/usr/local/webserver/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

再查找; cgi.fix_pathinfo=0

修改為cgi.fix_pathinfo=0，防止Nginx文件類型錯誤解析漏洞。

自動修改：若嫌手工修改麻煩，可執行以下shell命令，自動完成對php.ini文件的修改：

sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /usr/local/webserver/php/etc/php.ini

sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini

sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/webserver/php/etc/php.ini

sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/webserver/php/etc/php.ini

配置eAccelerator加速PHP：

mkdir -p /usr/local/webserver/eaccelerator_cache

vi /usr/local/webserver/php/etc/php.ini

[eaccelerator]

zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"

eaccelerator.shm_size="64"

eaccelerator.cache_dir="/usr/local/webserver/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"

創建www用戶和組，以及供虛擬主機使用的目錄：

/usr/sbin/groupadd www

/usr/sbin/useradd -g www www

mkdir -p /data0/htdocs/www

chmod +w /data0/htdocs/www

chown -R www:www /data0/htdocs/www

創建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/webserver/php/etc/目錄中創建php-fpm.conf文件：

rm -f /usr/local/webserver/php/etc/php-fpm.conf

vi /usr/local/webserver/php/etc/php-fpm.conf

輸入以下內容(如果您安裝 Nginx + PHP 用于程序調試，請將以下的0改為1，以便顯示PHP錯誤信息，否則，Nginx 會報狀態為500的空白錯誤頁)：

All relative paths in this config are relative to php's install prefix

Pid file

/usr/local/webserver/php/logs/php-fpm.pid

Error log file

/usr/local/webserver/php/logs/php-fpm.log

Log level

notice

When this amount of php processes exited with SIGSEGV or SIGBUS ...

10

... in a less than this interval of time, a graceful restart will be initiated.

Useful to work around accidental curruptions in accelerator's shared memory.

1m

Time limit on waiting child's reaction on signals from master

5s

Set to 'no' to debug fpm

yes

Name of pool. Used in logs and stats.

default

Address to accept fastcgi requests on.

Valid syntax is 'ip.ad.re.ss:port' or just 'port' or '/path/to/unix/socket'

127.0.0.1:9000

Set listen(2) backlog

-1

Set permissions for unix socket, if one used.

In Linux read/write permissions must be set in order to allow connections from web server.

Many BSD-derrived systems allow connections regardless of permissions.

0666

Additional php.ini defines, specific to this pool of workers.

/usr/sbin/sendmail -t -i

0

Unix user of processes

www

Unix group of processes

www

Process manager settings

Sets style of controling worker process count.

Valid values are 'static' and 'apache-like'

static

Sets the limit on the number of simultaneous requests that will be served.

Equivalent to Apache MaxClients directive.

Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi Used with any pm_style.

128

Settings group for 'apache-like' pm style

Sets the number of server processes created on startup.

Used only when 'apache-like' pm_style is selected

20

Sets the desired minimum number of idle server processes.

Used only when 'apache-like' pm_style is selected

5

Sets the desired maximum number of idle server processes.

Used only when 'apache-like' pm_style is selected

35

The timeout (in seconds) for serving a single request after which the worker process will be terminated

Should be used when 'max_execution_time' ini option does not stop script execution for some reason

'0s' means 'off'

0s

The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file

'0s' means 'off'

0s

The log file for slow requests

logs/slow.log

Set open file desc rlimit

65535

Set max core size rlimit

0

Chroot to this directory at the start, absolute path

Chdir to this directory at the start, absolute path

Redirect workers' stdout and stderr into main error log.

If not set, they will be redirected to /dev/null, according to FastCGI specs

yes

How much requests each process should execute before respawn.

Useful to work around memory leaks in 3rd party libraries.

For endless request processing please specify 0

Equivalent to PHP_FCGI_MAX_REQUESTS

1024

Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.

Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)

Makes sense only with AF_INET listening socket.

127.0.0.1

Pass environment variables like LD_LIBRARY_PATH

All $VARIABLEs are taken from current environment

$HOSTNAME

/usr/local/bin:/usr/bin:/bin

/tmp

/tmp

/tmp

$OSTYPE

$MACHTYPE

2

啟動php-cgi進程，監聽127.0.0.1的9000端口，進程數為128(如果服務器內存小于3GB，可以只開啟64個進程)，用戶為www：

ulimit -SHn 65535

/usr/local/webserver/php/sbin/php-fpm start

注：/usr/local/webserver/php/sbin/php-fpm還有其他參數，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。

nginx包

安裝Nginx所需的pcre庫：

tar zxvf pcre-8.10.tar.gz

cd pcre-8.10/

./configure

make && make install

cd ../

安裝Nginx

tar zxvf nginx-1.0.12.tar.gz

cd nginx-1.0.12/

./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module
