centos 7.3二进制安装mariadb10.2.8完美步骤

centos7安装MariaDB教程,分享给大家

 (1)在centos7系统上,yum info mariadb可以找到提供mariadb包的官方网站,在到官方网站下载最新的mariadb包,然后rz到linux系统上去

1.centos7现状:

 (2)准备用户

1.useradd -r -d /app/mysqldb -m -s /sbin/nologin mysql //-r创建系统用户,-d指定家目录,-m强制创建家目录,-s指定shell不允许这个用户登录

新系统无法再使用yum install
mysql-server来安装mysql,因为已使用mariadb代替mysql。

463.com,(3)准备数据库目录

2.安装mariadb:

创建mysql用户指定的家目录就是数据库目录,但是建议使用逻辑卷,因为这个目录是存放数据库的,会逐渐增大,而逻辑卷能够扩展。

(4)准备二进制程序

1.tar xvf mariadb-10.2.8-linux-x86_64.tar.gz -C /usr/local  //默认是放在/usr/local目录下
2.cd  /usr/local
3.ln -s mariadb-10.2.8-linux-x86_64.tar.gz/ mysq  //在/usr/local下, mariadb的数据库的目录已经生成,但是这个目录不符合要求,要求mariadb数据库必须放在mysql目录下,所以有两种方法解决,一是改名,将生成的mariadb数据库目录改为mysql,二是创建软链接,我们就选择创建软链接的方式

 

 

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。

(5)准备配置文件

1.cd /usr/local/mysql/support-files  //这个目录下的一些文件可以当mysql的配置文件,我们就选my-huge.cnf作为mysql的配置文件
2.mkdir /etc/mysql/  //建立mysql配置文件的目录
3.cp my-huge.cnf  /etc/mysql/my.cnf //mysql的配置文件名也是有要求的,所以要改名为my.cnf
4.vim  /etc/mysql/my.cnf   //复制过来之后还要修改一下配置文件
[mysqld]
datadir = /app/mysqldb //数据库的数据放在哪,关键的一行,必须加,下面两行可以不加
innodb_file_per_table = on//数据库中有很多表,加上这一行就可以使每个表单独生成一个文件
skip_name_resolve = on  //为了加速访问速度,忽略名字的反向解析
这样配置文件就编辑好了

 

(6)创建数据库文件

1.cd /usr/local/mysql/
2.scripts/mysql_install_db  --user=mysql --datadir=/app/mysqldb //创建mysql的数据库,指定数据库的路径以及用户名身份,执行完之后就会在/app/mysqldb下生成了数据库文件。
注意:创建mysql的系统数据库,系统提供了一个脚本,我们直接可以利用它来生成mysql的系统数据库,这个脚本就在scripts下,但是不要进去运行脚本,否则会报错,必须在/usr/local/mysql/下运行脚本
3.ls /app/mysqldb //查看一下生成的数据库文件
