安装mariadb

Posted 2022-04-14 xuqidong

 安装mariadb有两个源，一个是阿里云的yum源，可能版本较低，软件包很小，功能很少

二个是mariadb官方的yum源，配置方式

在/etc/yum.repos.d目录下，建立一个repo文件就是yum仓库

#创建一个mariadb.repo文件，写入以下内容
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

2安装mariadb，查看官方的版本号和软件包信息

 yum install MariaDB-server MariaDB-client -y

3在安装好mysql后，进行初始化

 mysql_secure_installation

4进行mysql数据库编码统一，修改/etc/my.cnf配置如下

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
character-set-server=utf8
collation-server=utf8_general_ci
log-error=/var/log/mysqld.log
# 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

[client]
default-character-set=utf8
[mysql]
default-character-set=utf8

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

5授权mysql进行远程登录
