LInux安装MySQL5.7.24详情

安装包下载

MySQL 的官网下载地址：http://www.mysql.com/downloads/

我安装的是5.7版本

第二步：

选择：TAR

(mysql-5.7.24-el7-x86_64.tar)   点击下载

然后点击 No thanks, just start my download. 进行下载。

检查是否安装过mysql

[root@master mysql]# rpm -qa|grep mysql
mysql-community-common-5.7.10-1.el7.x86_64
mysql-community-libs-5.7.10-1.el7.x86_64
mysql-community-server-5.7.10-1.el7.x86_64
qt-mysql-4.8.5-13.el7.x86_64
mysql-community-client-5.7.10-1.el7.x86_64

下载已经安装

[root@master mysql]# rpm -e --nodeps mysql-community-common-5.7.10-1.el7.x86_64
[root@master mysql]# rpm -e --nodeps mysql-community-common-5.7.10-1.el7.x86_64
[root@master mysql]# rpm -e --nodeps mysql-community-libs-5.7.10-1.el7.x86_64
[root@master mysql]# rpm -e --nodeps mysql-community-server-5.7.10-1.el7.x86_64
[root@master mysql]# rpm -e --nodeps qt-mysql-4.8.5-13.el7.x86_64
[root@master mysql]# rpm -e --nodeps mysql-community-client-5.7.10-1.el7.x86_64
再次查看
[root@master mysql]#  rpm -qa|grep mysql
[root@master mysql]#

查看是否按照自带的mariadb数据库

[root@master mysql]# rpm -qa|grep -i mariadb
5.MySQL的server端需要Perl支持，安装一下
[root@master mysql]# yum install perl -y

检查mysql组和用户

是否存在，如无创建：
[root@master mysql]# cat /etc/group | grep mysql
[root@master mysql]# cat /etc/passwd |grep mysql
[root@master mysql]# groupadd mysql
[root@master mysql]# useradd -r -g mysql mysql

放置安装包

从官网下载mysql安装包，解压后移动到/usr/local/mysql下
[root@master mysql]# ls
bin  COPYING  COPYING-test  data  docs  include  lib  man  mysql-test  README  README-test  share  support-files

创建数据目录data

mkdir -p  /usr/local/mysql/data

cd /usr/local

chown -R mysql:mysql mysql/

chmod -R 755 mysql/

安装初始化MySQL

[root@master bin]# /usr/local/mysql/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql
