1.3- 初始化数据库

#初始化数据库
/usr/local/mysql/bin/mysqld –initialize

1.4- 添加配置文件

cp /usr/local/support-files/my-default.cnf /etc/my.cnf
vim /etc/my.cnf

socket=/usr/local/mysql/mysql.sock

1.5- 配置mysql服务

cp support-files/mysql.server /etc/init.d/mysqld
chkconfig --add mysqld     # 添加到系统服务
chkconfig mysqld on        # 开机启动

1.6- 启动服务

service mysqld start

故障处理：



/usr/local/mysql 里面没有mysql.pid文件

解决办法：

vim  /etc/selinux/config，把SELINUX=enforcing改为SELINUX=disabled后存盘退出重启机器试试。
service mysqld stop        # 停止mysql服务
service mysqld restart     # 重新启动mysql服务
