   1:MySQL-server           ########################################### [100%]

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h GZSB-CJB-SHH1-13-MAEGIS-0.130 password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

Please report any problems with the /usr/bin/mysqlbug script!

配置

配置文件

mysql 配置文件是 /etc/my.cnf，但是 rpm 方式安装的话，这个文件并不存在，这时只需要将 /usr/share/mysql/my-medium.cnf
复制到 /etc下并更名为 my.cnf 即可

默认字符集

编辑 /etc/my.cnf，将默认字符集修改为utf8mb4

在 [client] 小节，增加 default-character-set=utf8mb4
在 [mysqld] 小节，增加 character-set_server=utf8mb4，注意不要用default-character-set=utf8mb4，
否则 mysql 无法启动

修改文件路径

关闭MySql

service mysql stop

转移数据

cd /var/lib
cp -a mysql /data/mysqldata/

修改配置文件

 [client]
  #socket         = /var/lib/mysql/mysql.sock
  socket          = /data/mysqldata/mysql/mysql.sock
  
 [mysqld]
  #socket         = /var/lib/mysql/mysql.sock
  socket          = /data/mysqldata/mysql/mysql.sock
  datadir=/data/mysqldata/mysql

启动MySql

service mysql start

这样以后mysql文件全部转移到 /data/mysqldata/mysql 目录
