cenotos 卸载mysql_CentOS 6.2编译安装Nginx1.0.12+MySQL5.5.21+PHP5.3.10 | 系统运维
說明：
操作系統：CentOS 6.2 32位
系統安裝教程：CentOS 6.2安裝(超級詳細圖解教程)準備篇：
一、配置好IP、DNS 、網關，確保使用遠程連接工具能夠連接服務器
CentOS 設置IP地址、網關、DNS教程：http://www.osyunwei.com/archives/423.html
二、配置防火墻，開啟80端口、3306端口
vi /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT(允許80端口通過防火墻)
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT(允許3306端口通過防火墻)
特別提示：很多網友把這兩條規則添加到防火墻配置的最后一行，導致防火墻啟動失敗，正確的應該是添加到默認的22端口這條規則的下面
添加好之后防火墻規則如下所示：

-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
#########################################################
/etc/init.d/iptables restart? #最后重啟防火墻使配置生效
三、關閉SELINUX
vi /etc/selinux/config
#SELINUX=enforcing?????? #注釋掉
#SELINUXTYPE=targeted??? #注釋掉
SELINUX=disabled???????? #增加
:wq? 保存，關閉
shutdown -r now?? #重啟系統
四 、系統約定
軟件源代碼包存放位置：/usr/local/src
源碼包編譯安裝位置：/usr/local/軟件名字
五、下載軟件包
1、下載nginx(目前穩定版)
http://nginx.org/download/nginx-1.0.12.tar.gz
2、下載pcre? (支持nginx偽靜態)
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.30.tar.gz
3、下載MySQL
http://mysql.mirror.kangaroot.net/Downloads/MySQL-5.5/mysql-5.5.21.tar.gz
4、下載php
http://cn.php.net/distributions/php-5.3.10.tar.gz
5、下載cmake(MySQL編譯工具)
http://www.cmake.org/files/v2.8/cmake-2.8.7.tar.gz
6、下載libmcrypt(PHPlibmcrypt模塊)
ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/libmcrypt/libmcrypt-2.5.7.tar.gz
7、下載Zend Guard
http://downloads.zend.com/guard/5.5.0/ZendGuardLoader-php-5.3-linux-glibc23-i386.tar.gz
六、安裝編譯工具及庫文件(使用CentOS yum命令安裝)
yum install make apr* autoconf automake curl curl-devel?gcc gcc-c++ zlib-devel openssl openssl-devel pcre-devel gd? kernel keyutils? patch? perl kernel-headers compat* mpfr cpp glibc libgomp libstdc++-devel ppl cloog-ppl keyutils-libs-devel libcom_err-devel libsepol-devel libselinux-devel krb5-devel zlib-devel libXpm* freetype libjpeg* libpng* php-common php-gd ncurses* libtool* libxml2 libxml2-devel patch
安裝篇
以下是用putty工具遠程登錄到服務器，在命令行下面操作的
一、安裝libmcrypt
cd /usr/local/src
tar zxvf? libmcrypt-2.5.7.tar.gz?? #解壓
cd? libmcrypt-2.5.7 #進入目錄
./configure??? #配置
make?????????? #編譯
make install?? #安裝
二、安裝cmake
cd /usr/local/src
tar zxvf cmake-2.8.7.tar.gz
cd cmake-2.8.7
./configure
make?????????? #編譯
make install?? #安裝
三、安裝pcre
cd /usr/local/src
mkdir /usr/local/pcre? #創建安裝目錄
tar? zxvf pcre-8.30.tar.gz
cd pcre-8.30
./configure? --prefix=/usr/local/pcre? #配置
make
make install
四、安裝mysql
groupadd mysql? #添加mysql組
useradd -g mysql mysql -s /bin/false? #創建用戶mysql并加入到mysql組，不允許mysql用戶直接登錄系統
mkdir -p /data/mysql? #創建MySQL數據庫存放目錄
chown -R mysql:mysql /data/mysql?? #設置MySQL數據庫目錄權限
mkdir -p /usr/local/mysql #創建MySQL安裝目錄
cd /usr/local/src
tar zxvf mysql-5.5.21.tar.gz? #解壓
cd mysql-5.5.21
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql? -DMYSQL_DATADIR=/data/mysql? -DSYSCONFDIR=/etc?? #配置
make #編譯
make install? #安裝
cd /usr/local/mysql
cp ./support-files/my-huge.cnf? /etc/my.cnf?? #拷貝配置文件(注意：如果/etc目錄下面默認有一個my.cnf，直接覆蓋即可)
vi /etc/my.cnf?? #編輯配置文件,在 [mysqld] 部分增加
datadir = /data/mysql? #添加MySQL數據庫路徑
./scripts/mysql_install_db --user=mysql? #生成mysql系統數據庫
cp ./support-files/mysql.server? /etc/rc.d/init.d/mysqld? #把Mysql加入系統啟動
chmod 755 /etc/init.d/mysqld?? #增加執行權限
chkconfig mysqld on? #加入開機啟動
vi /etc/rc.d/init.d/mysqld? #編輯
basedir = /usr/local/mysql?? #MySQL程序安裝路徑
datadir = /data/mysql? #MySQl數據庫存放目錄
service mysqld start? #啟動
vi /etc/profile?? #把mysql服務加入系統環境變量：在最后添加下面這一行
export PATH=$PATH:/usr/local/mysql/bin
下面這兩行把myslq的庫文件鏈接到系統默認的位置，這樣你在編譯類似PHP等軟件時可以不用指定mysql的庫文件地址。
ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql
ln -s /usr/local/mysql/include/mysql /usr/include/mysql
shutdown -r now???? #需要重啟系統，等待系統重新啟動之后繼續在終端命令行下面操作
mysql_secure_installation??? #設置Mysql密碼
根據提示按Y 回車輸入2次密碼
或者直接修改密碼/usr/local/mysql/bin/mysqladmin -u root -p password "123456" #修改密碼
service mysqld restart? #重啟
到此，mysql安裝完成！
五、安裝 nginx
groupadd? www? #添加www組
useradd -g? www www -s /bin/false? #創建nginx運行賬戶www并加入到www組，不允許www用戶直接登錄系統cd /usr/local/src
tar? zxvf nginx-1.0.12.tar.gz
cd nginx-1.0.12
./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-openssl=/usr/ --with-pcre=/usr/local/src/pcre-8.30
注意:--with-pcre=/usr/local/src/pcre-8.30指向的是源碼包解壓的路徑，而不是安裝的路徑，否則會報錯
make
make install
/usr/local/nginx/sbin/nginx?? #啟動nginx
設置nginx開啟啟動
vi /etc/rc.d/init.d/nginx??? #編輯啟動文件添加下面內容
=======================================================
#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
