redhat7.4离线安装mysql5.7

由于项目需要，需要在rh7.4上安装mysql版本，之前6.8的环境直接挂载iso yum源安装，rh7以上的版本只有手工安装了

1.安装前准备

到mysql官网下载相应的rpm包

下载地址：https://dev.mysql.com/downloads/mysql/5.7.html#downloads

选择自己需要的版本

 官网下载速度较慢，有需要的可以到我的共享下载

2.通过scp上传至需要安装的服务器并解压

tar -xvf mysql-5.7.26-1.el7.x86_64.rpm-bundle.tar -C /opt/

解压后文件

mysql-community-embedded-devel-5.7.26-1.el7.x86_64.rpm mysql-community-libs-5.7.26-1.el7.x86_64.rpm mysql-community-embedded-5.7.26-1.el7.x86_64.rpm mysql-community-test-5.7.26-1.el7.x86_64.rpm mysql-community-embedded-compat-5.7.26-1.el7.x86_64.rpm mysql-community-common-5.7.26-1.el7.x86_64.rpm mysql-community-devel-5.7.26-1.el7.x86_64.rpm mysql-community-client-5.7.26-1.el7.x86_64.rpm mysql-community-server-5.7.26-1.el7.x86_64.rpm mysql-community-libs-compat-5.7.26-1.el7.x86_64.rpm

 

 

 

 

 

 

 

3.考虑到安装包依赖关系，通过rpm按照顺序安装

rpm -ivh mysql-community-common-5.7.26-1.el7.x86_64.rpm rpm -ivh mysql-community-libs-5.7.26-1.el7.x86_64.rpm rpm -ivh mysql-community-client-5.7.26-1.el7.x86_64.rpm rpm -ivh mysql-community-libs-compat-5.7.26-1.el7.x86_64.rpm rpm -ivh mysql-community-server-5.7.26-1.el7.x86_64.rpm

 

 

 

 

4.启动并查看mysql状态

systemctl start mysqld.service systemctl status mysqld.service

 

 

 

5.通过/var/log/mysqld.log查找mysql密码并登陆

[root@hadoop-2 log]# grep "pass"  mysqld.log 2019-06-19T00:59:58.620256Z 1 [Note] A temporary password is generated for root@localhost: Ve9vP 2019-06-19T01:00:20.364725Z 2 [Note] Access denied for user 'root'@'localhost' (using password: NO) [root@hadoop-2 opt]# mysql -uroot -p mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Abcde2008!';
