安装mariadb并修改配置文件

实验环境：CentOS7

#安装mariadb-server包
#修改mariadb配置文件/etc/my.cnf.d/server.cnf
#添加 skip_name_resolve=ON　　#不执行将IP解析成主机名
#添加 innodb_file_per_table=ON　　#每个innodb表单独的表空间
[root@~ localhost]#yum -y install mariadb-server
[root@~ localhost]#vi /etc/my.cnf.d/server.cnf 

#
# These groups are read by MariaDB server.
# Use it for options that only the server (but not clients) should see
#
# See the examples of server my.cnf files in /usr/share/mysql/
#

# this is read by the standalone daemon and embedded servers
[server]

# this is only for the mysqld standalone daemon
[mysqld]
skip_name_resolve=ON
innodb_file_per_table=ON
log_bin=mysql-bin    #二进制日志

#查看服务的状态，mariadb.service监听端口3306
[root@~ localhost]#systemctl status mariadb.service
● mariadb.service - MariaDB database server
   Loaded: loaded (/usr/lib/systemd/system/mariadb.service; disabled; vendor preset: disabled)
   Active: active (running) since 星期六 2017-06-03 08:19:01 CST; 2h 1min ago
[root@~ localhost]#ss -ntl|grep "3306"
LISTEN     0      50           *:3306                     *:*    

首次安装完成mariadb-server包后，启动mariadb.service，必须加固数据库，执行

[root@~ localhost]#mysql_secure_installation
