更改mysql安装目录的属主属组并添加mysql环境变量
[root@server1 mysql]# chown -R mysql.mysql . [root@server1 mysql]# vim /etc/profile.d/mysql.sh export PATH=$PATH:/usr/local/mysql/bin加入服务列表并设置为开机自启
[root@server1 ~]# cd /usr/local/mysql/support-files/ [root@server1 support-files]# cp mysql.server /etc/init.d/mysqld [root@server1 support-files]# chmod +x /etc/init.d/mysqld # 添加一个执行权限 [root@server1 support-files]# chkconfig mysqld on [root@server1 support-files]# chkconfig mysqld --level 2345 on [root@server1 support-files]# chkconfig --list mysqld [root@server1 support-files]# chkconfig --list mysqld mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off修改mysql的配置文件，以下内容为自选
