mariadb安装操作

Posted 2022-06-25 hanbinglengxie

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

 以后再优化
