–添加用户：
groupadd mysql
useradd -r -g mysql -s /bin/false mysql
—
或者直接：
useradd mysql
cp -a /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
–创建数据目录：
mkdir -p /app/data/log
mkdir -p /app/data/log/binlog
mkdir -p /app/data/run
mkdir -p /app/data/tmp
mkdir -p /app/data/log/iblog
chown -R mysql:mysql /app/data/
–初始化数据库：
[root@test1 ~]# su – mysql
[mysql@test1 ~]$ /usr/local/mysql/bin/mysqld –defaults-file=/etc/my.cnf –initialize –user=mysql
2.1 通脚本启动：
启动数据库：
[mysql@test1 log]$ /etc/init.d/mysqld start
Starting MySQL.. [ OK ]
关闭数据库：
[mysql@test1 log]$ /etc/init.d/mysqld stop
Shutting down MySQL.. [ OK ]
登录数据库：
[mysql@test1 log]$ /usr/local/mysql/bin/mysql -uroot -p
修改密码：
mysql> alter user root@’localhost’ identified by ‘MYsql#123’;
Query OK, 0 rows affected (0.00 sec)
2.2 自定义配置文件启动：
启动数据库：
[mysql@test1 log]$ /usr/local/mysql/bin/mysqld_safe –defaults-file=/etc/my.cnf –user=mysql &
关闭数据库：
[mysql@test1 log]$ /usr/local/mysql/bin/mysqladmin –port=3306 shutdown -p
Enter password:
3.开机自动启动：
[root@test1 ~]# chkconfig mysqld on
