MariaDB部署

系统：CentOS Linux release 7.8.2003 (Core)

内核：3.10.0-693.el7.x86_64

1.安装启动MariaDB

安装mariadb 和 mariadb-server

 yum install -y mariadb mariadb-server

配置开机自启动并启动服务

 systemctl enable --now mariadb

2.配置MariaDB

备份原有配置文件

 cp /etc/my.cnf{,.bak}

 cp /etc/my.cnf.d/client.cnf{,.bak}

 cp /etc/my.cnf.d/mysql-clients.cnf{,.bak}

修改配置文件

  cat /etc/my.cnf

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

# 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

    init_connect="SET collation_connection = utf8_unicode_ci"

    init_connect="SET NAMES utf8"

    character-set-server=utf8

    collation-server=utf8_unicode_ci

    skip-character-set-client-handshake

    transaction-isolation=READ-COMMITTED

[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

 cat /etc/my.cnf.d/mysql-clients.cnf

#

# These groups are read by MariaDB command-line tools

# Use it for options that affect only one utility

#

[mysql]

    default-character-set=utf8

[mysql_upgrade]

[mysqladmin]

[mysqlbinlog]

[mysqlcheck]

[mysqldump]

[mysqlimport]

[mysqlshow]

[mysqlslap]

 cat /etc/my.cnf.d/client.cnf
#
# These two groups are read by the client library
# Use it for options that affect all clients, but not the server
#
[client]
    default-character-set=utf8
# This group is not read by mysql client library,
# If you use the same .cnf file for MySQL and MariaDB,
# use it for MariaDB-only client options
[client-mariadb]

重启mariadb服务

 systemctl restart mariadb.service
 systemctl status mariadb.service

3.设置密码

 mysql_secure_installation

重启mariadb服务

 systemctl restart mariadb.service

4.验证部署结果

  mysql -u root -p

Enter password:

MariaDB [(none)]> show variables like "%character%";

MariaDB [(none)]> show variables like "%collation%";

5.常用SQL--创建数据库并授权远程访问

MariaDB [(none)]> create database confluence default character set utf8 collate utf8_bin;

MariaDB [(none)]> grant all on confluence.* to "admin"@"%" identified by "admin";

MariaDB[(none)]> grant all on confluence.* to "admin"@"localhost" identified by"admin";

MariaDB [(none)]> flush privileges;

至此，MariaDB部署完毕。
