安装

yum install -y mariadb mariadb-server

systemctl start mariadb

mysql -u root

set password=password('密码')

设置权限

use mysql

delete from user where password=''

update user set host='%' \#设置远程可以访问

flush privileges;

如果远程访问不了，请检查防火墙

查看方式 systemctl status firewalld

停止及取消开机自动启动

systemctl disable firewalld

systemctl stop firewalld

安装完毕

修改数据库存放位置

分三个步骤

1、配置my.cnf 位置/etc/my.cnf

\[mysqld\]  
datadir=/vdata/mysql\_data/  
socket=/vdata/mysql\_data/mysql.sock  
wait\_timeout=2880000  \#优化  
max\_allowed\_packet=128M   \#优化  
interactive\_time=280000  \#优化  
thread\_concurrency=20  \#优化  
max\_connections=1500  \#优化  
max\_connect\_errors=30  \#优化  
table\_open\_cache=1024  \#优化  
myisam\_sort\_buffer\_size=32M  \#优化  
bulk\_insert\_buffer\_size=32M  \#优化

\# 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

2、配置server.cnf  位置/etc/my.cnf.d/server.cnf

\[mysqld\]  
datadir=/vdata/mysql\_data/  
socket=/vdata/mysql\_data/mysql.sock

3、配置client /etc/my.cnf.d/client.cnf

\[mysqld\]  
socket=/vdata/mysql\_data/mysql.sock

配置数据库到/vdata/mysql\_data 完毕。

重新启动mariadb

systemctl restart mariadb

如果启动不了

请检查/etc/selinux/config，enforinng是否是disable，如果不是改为disable

chmod -R mysql:mysql /vdata/mysql\_data \#为mysql数据库目录设置权限
