设置为开机启动(2、3、4都是on代表开机自动启动)

[[email protected] ~]# chkconfig --list | grep mysqld
mysqld         	0:off	1:off	2:off	3:on	4:on	5:on	6:off
[[email protected] ~]# chkconfig mysqld on
[[email protected] ~]# chkconfig --list | grep mysqld
mysqld         	0:off	1:off	2:on	3:on	4:on	5:on	6:off

三、设置远程root
启动mysql

# service mysqld start

设置root密码

# mysql_secure_installation

登陆root账号

# mysql -uroot -p

建立远程root用户

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '你设置的密码' WITH GRANT OPTION;
mysql> flush privileges;

四、设置utf-8编码

查看mysql原本编码：

mysql> show variables like 'character%';

设置编码

# vi /etc/my.cnf

如下(少补)：

[mysqld]
character-set-server=utf8 
collation-server=utf8_general_ci 
sql_mode='NO_ENGINE_SUBSTITUTION'
[mysql]
default-character-set = utf8

[mysql.server]
default-character-set = utf8


[mysqld_safe]
default-character-set = utf8


[client]
default-character-set = utf8

重启mysql

# service mysqld restart

再次查看编码：

     # mysql -uroot -p
mysql> show variables like 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
