CentOS6.5安装MySql、Apache、PHP

一、安装MySql

1、卸载CentOS自带的MySql

获取root权限先，卸载CentOS自带的MySql

yum remove mysql

2、安装cmake

下载cmake

wget http://www.cmake.org/files/v2.8/cmake-2.8.5.tar.gz

安装

cd cmake-2.8.5
./configure  --prefix=/usr/local/cmake
make
make install

3、安装MySql

下载mysql.tar.gz包，这里用的是mysql-5.6.17.tar.gz

所以在这里我们要建一个msyql的用户和组

/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql

创建目录

mkdir /usr/local/mysql   
mkdir /usr/local/mysql/data 

解压mysql-5.6.17.tar.gz并进行安装

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql
make
make install

加权限

chmod +w /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql

进入/usr/local/mysql目录

scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql  //初始化MySql数据库
cp support-files/my-medium.cnf /usr/local/mysql/my.cnf     //copy配置文件

修改配置文件/usr/local/mysql/my.cnf

[mysqld]   
basedir = /usr/local/mysql   
datadir = /usr/local/mysql/data    
port = 3306
user = mysql 

启动MySql

cd /usr/local/mysql/support-files/
cp ./mysql.server /etc/init.d/mysqld
/etc/init.d/mysqld start

关闭MySql

/etc/init.d/mysqld stop

二、安装apache server

1、卸载系统自带的httpd

rpm -qa|grep httpd
rpm -e  xxx

2、下载apache-server

在安装之前还得先安装APR、APR-util（两者下载地址http://apr.apache.org/download.cgi）、以及pcre（http://ftp.exim.llorien.org/pcre/）

1）安装apr，否则./configure httpd时，会发生error: APR not found. 

mkdir /usr/local/apr
tar -zxf apr-1.5.1.tar.gz
./configure --prefix=/usr/local/apr
make
make install

2）安装apr-util，否则./configure httpd时，会发生error: APR-util not found. 

mkdir /usr/local/apr
tar -zxf apr-util-1.5.3.tar.gz
./configure --prefix=/usr/local/apr-util
make
make install

3）安装pcre，否则./configure httpd时，会发生error:pcre-config for libpcre not found.

mkdir /usr/local/pcre
unzip -o pcre-8.35.zip
cd pcre-8.35
/configure --prefix=/usr/local/pcre
make
make install

4）最后安装httpd

mkdir /usr/local/apache
tar zxvf httpd-2.4.9.tar.gz
cd httpd-2.4.9
./configure --prefix=/usr/local/apache --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre/
make
make install

5）启动

/usr/local/apache/bin/apachectl start

浏览器访问http://localhost

显示It works！，OK apache server配置好了

三、安装PHP

1、下载php，这里用的是php-5.5.12.tar.gz

2、准备工作

yum install libxml2
yum install libxml2-devel -y

错过这一步，会报待会./configure php时候，会报xml2-config not found.

详情可以参考这里http://www.jsjtt.com/xitongyingyong/linux/17.html

yum install libjpeg-devel

错过这一步，待会./configure php时候，会报error: jpeglib.h not found.

要是在下文./configure php时候发生错误，可以参考这里解决方案http://www.cnlvzi.com/index.php/Index/article/id/143

3、安装PHP

1）安装

tar zxvf php-5.5.12.tar.gz
cd php-5.5.12
./configure --with-apxs2=/usr/local/apache/bin/apxs --with-zlib-dir --with-libxml-dir --with-jpeg-dir --with-png-dir --with-gd --with-mysql=/usr/local/mysql --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mbstring 
make 
make install

2）配置php.ini文件，操作位于解压目录下

cp php.ini-development /usr/local/php/lib/php.ini 

3）配置apache支持php

修改vi  /usr/lcoal/apache/conf/httpd.conf

通过“/”来查找到AddType application/x-gzip .tgz，这里需要注意的是，不是带有的注意标记的#，在找到AddType application/x-gzip .tgz的后面添加：

AddType application/x-httpd-php .php .phtml
AddType application/x-httpd-php-source .phps

表示apache服务中可以解析php格式文件 

重启apache

/usr/local/apache/bin/apachectrl start
