安装
1 yum -y install mariadb mariadb-server
这是centos的命令，ubuntu不用安装。
启动
1 systemctl start mariadb #启动MariaDB 2 3 systemctl enable mariadb #设置开机启动 4 5 #ubuntu 6 update-rc.d mysql defaults 7 systemctl start mysql
设置密码
1 mysql_secure_installation
修改字符集
centos
1 vi /etc/my.cnf 2 3 #在[mysqld]标签下添加 4 init_connect='SET collation_connection = utf8_unicode_ci' 5 init_connect='SET NAMES utf8' 6 character-set-server=utf8 7 collation-server=utf8_unicode_ci 8 skip-character-set-client-handshake 9 10 vi /etc/my.cnf.d/client.cnf 11 12 #在[client]中添加 13 default-character-set=utf8 14 15 vi /etc/my.cnf.d/mysql-clients.cnf 16 17 #在[mysql]中添加 18 default-character-set=utf8 19 20 systemctl restart mariadb #重启mariadb
ubuntu
1 vim /etc/mysql/mariadb.conf.d/50-server.cnf 2 3 #bind-address = 127.0.0.1 注释掉这行 4 5 #在[mysqld]标签下添加 6 skip-character-set-client-handshake
ubuntu自带的mariadb的字符集为utf8bm4,添加skip-character-set-client-handshake设置会忽略client的字符集，始终与server保持一致。
1 mysql -uroot -p123456 2 #查看字符集 3 show variables like "%character%"; 4 show variables like "%collation%";
创建用户，授权
