zabbix的MariaDB数据库改变存储位置

#创建

mkdir /公司缩写/mysql

#停止数据库服务

systemctl status mariadb.service
systemctl stop mariadb.service

#把数据库文件移动到新的存储位置

cp -rp /var/lib/mysql/ /公司缩写/mysql/

#修改后的数据库配置文件

[root@iZkdZ ~]# cat /etc/my.cnf
[mysqld]
datadir=/公司缩写/mysql
socket=/公司缩写/mysql/mysql.sock
lower_case_table_names         = 1
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd 
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

#启动数据库

systemctl start mariadb.service
systemctl status mariadb.service

#新的登录数据库的命令，需要指定mysql.sock

mysql -uzabbix -p123456 -S /公司缩写/mysql/mysql.sock

#创建软链接，否则，zabbix页面无法打开

mkdir /var/lib/mysql
ln -s /公司缩写/mysql/mysql.sock /var/lib/mysql/mysql.sock

　　在这一步之前，我是把原始的/var/lib/mysql目录改名为/var/lib/mysql_ori。所以，会有创建/var/lib/mysql的命令。在下面确认重启zabbix服务端没有问题，web界面可以正常打开。我才把原始的/var/lib/mysql目录移动到/tmp目录，后来又移动到公司默认的目录，作为备份存放。

#重启zabbix

systemctl restart zabbix-server.service
