CentOS7安装MariaDB10.1.14

1、下载MariaDB

下载地址：https://downloads.mariadb.org/mariadb/10.1.14/

这里选择mariadb-10.1.14-linux-x86_64.tar.gz，下载过程中如果出现404错误，可以在网站右下角选择其他镜像地址，下载完成后，使用pscp工具将其传送到CentOS中

2、解压缩

[root@localhost ~]# cd /usr/local/
[root@localhost local]# tar -zxvf mariadb-10.1.14-linux-x86_64.tar.gz
[root@localhost local]# mv mariadb-10.1.14-linux-x86_64 mysql

3、初始化数据库

[root@localhost local]# groupadd mysql

[root@localhost local]# useradd -r -g mysql -s /bin/false mysql

[root@localhost local]# cd mysql

[root@localhost mysql]# chown -R root:root .

[root@localhost mysql]# chown -R mysql:mysql data

[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --datadir=./data

4、修改配置文件，并设置utf8编码格式、启动慢查询日志

[root@localhost mysql]# cp ./support-files/my-huge.cnf /etc/my.cnf

[root@localhost mysql]# vim /etc/my.cnf

[mysql]

default-character-set=utf8

...

[mysqld]

character-set-server=utf8

collation-server=utf8_general_ci

slow_query_log = 1

...

5、启动mysql服务、设置root密码

[root@localhost mysql]# ./bin/mysqld_safe --user=mysql &

[root@localhost mysql]# ./bin/mysqladmin -uroot password 'root'

6、使用mysql客户端

[root@localhost mysql]# mysql -uroot -proot

7、注册系统服务
[root@localhost mysql]# cp ./support-files/mysql.server /etc/init.d/mysqld

[root@localhost mysql]#  chkconfig --add mysqld # 加入开机自动启动

[root@localhost mysql]# systemctl start mysqld

8、遇到的问题

启动mysql服务时候，提示错误

/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

安装libaio-devl开发库即可

[root@localhost mysql]# yum install -y libaio-devel
