[root@rhel6 scripts]# cp /opt/mysql/mysql5.6.18/support-files/mysql.server /etc/init.d/mysqld
[root@rhel6 scripts]# cp /opt/mysql/mysql5.6.18/support-files/my-default.cnf /etc/my.cnf
cp: overwrite `/etc/my.cnf'? yes
注意不要使用系统自带的/etc/my.cnf文件，否则启动mysql服务时会报错。
Starting MySql.. ERROR! The server quit without updating PID file(/var/mysql/data/rhel6.pid).
5、修改参数
[root@rhel6 scripts]# vi /etc/init.d/mysqld
##修改下面两个参数如下
basedir=/opt/mysql/mysql5.6.18
datadir=/mysqldata
6、加入开机启动
[root@rhel6 scripts]# chkconfig --levels 235 mysqld on
[root@rhel6 scripts]# chkconfig --list mysqld
mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
7、启动mysql服务
[root@rhel6 scripts]# service mysqld start
Starting MySQL. SUCCESS!
8、连接mysql
[root@rhel6 scripts]# mysql -uroot
