2.mysql安装5.7以下
下载mysql选择source code。需要下载gcc-c++ ，ncurses， ncurses-devel， cmake，
增加程序用户：
Useradd –M –s /sbin/nologin mysql
编译安装
Cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql 主程序安装目录
-DSYSCONFDIR=/etc
-DDEFAULT_CHARSET=utf8 默认字符集为utf-8
-DDEFAULT_COLLATION=utf8_general_ci 默认的字符校对规则
-DWITH_EXTRA_CHARSETS=all 安装所有字符集
修改mysql安装目录的属猪
chown –R mysql:mysql /usr/local/mysql
添加系统服务
cp support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
mysqld –-add
mysqld –list
添加mysql命令执行的路径到PATH环境变量
echo “export PATH=$PATH:/usr/local/mysql/bin”>>/etc/profile
执行mysql_install_db脚本初始化数据库
/usr/local/mysql/scripts/mysql_install_db
–user=mysql 指定用户身份
–basedir=/usr/local/mysql 指定安装目录
–datadir=/usr/local/mysql/data/ 指定数据目录
一定要保证data目录的属主是mysql：mysql
chown –R mysql:mysql mysql

–with-libxml-dir=/usr/local/libxml2/
–with-png-dir=/usr/local/libpng/
–with-jpeg-dir=/usr/local/jpeg/
–with-freetype-dir=/usr/local/freetype/
–with-gd=/usr/local/gd/
–with-zlib-dir=/usr/local/zlib/
–with-mcrypt=/usr/local/libmcrypt/
–with-mysqli=/usr/local/mysql/bin/mysql_config
–enable-soap 变量激活soap和web service支持
–enable-mbstring=all 使多字节字符串知识
–enable-sockets 变量激活socket通信特性
1、#vim /etc/httpd/httpd.conf
找到：AddType application/x-gzip .gz .tgz
在该行下面添加：AddType application/x-httpd-php .php
2、找到:

将该行改为:
DirectoryIndex index.html index.htm index.php
3、找到：ServerName www.example.com:80
修改为：ServerName localhost:80
4、不改会出现403错误
