Red Hat7.2 上安装 MySQL5.5.58

Posted 2020-10-11 dy9776

 

1、首先查看linux版本：cat /etc/redhat-release

Red Hat Enterprise Linux Server release 7.2 (Maipo)

2.Linux查看版本说明当前CPU运行在32bit模式下， 但不代表CPU不支持64bit）:

getconf LONG_BIT

64.

3.关闭防护墙
查看：
chkconfig --list | grep iptables

chkconfig iptables off （设置自动启动为关闭）

(# chkconfig --del iptables （移除开机自动启动）)

 

4.当官方网站上下载对应的mysql, 根据上面信息

https://dev.mysql.com/downloads/mysql/5.5.html?os=31&version=5.1

下载(mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar)  

bundle版本的 是要安装的全部包括了，方便

 

5.用 ssh 工具上次的linux 上对应一个文件

[root@node04 Downloads]# ll
total 235312
-rw-r--r-- 1 root root 172994560 Oct 21 15:33 MySQL-5.5.58-1.el7.x86_64.rpm-bundle.tar

 

6. 注意：的是要切换的root用户  使用 su root切换用户

解压之后就是出现了好多的rpm文件

解压mysql5.5的安装包

tar -xvf MySQL-5.5.39-2.el6.x86_64.rpm-bundle.tar

 

但是安装只需要需要如下几个文件：

[root@node04 Downloads]# ll
-rw-r--r-- 1 7155 31415 16025016 Sep 14 14:24 MySQL-client-5.5.58-1.el7.x86_64.rpm
-rw-r--r-- 1 7155 31415 4394260 Sep 14 14:24 MySQL-devel-5.5.58-1.el7.x86_64.rpm
-rw-r--r-- 1 7155 31415 47529380 Sep 14 14:24 MySQL-server-5.5.58-1.el7.x86_64.rpm

 

7. 利用 rpm  安装 文件

rpm  -ivh   MySQL-client-5.5.58-1.el7.x86_64.rpm

rpm  -ivh   MySQL-devel-5.5.58-1.el7.x86_64.rpm

rpm  -ivh  MySQL-server-5.5.58-1.el7.x86_64.rpm

 

8. 接着就是初始化数据库。十分简单

/usr/bin/mysql_install_db

如图：

 

9.接下来就是查看mysql的状态

 service mysql status

 

可能是应为 有进程在占用 ，或者 磁盘已满 （查看命令df -h）

查看进程：netstat -anp | grep mysql

将里面 启动的进程杀死 。  kill -9  进程id 

 

11. 启动一下

/etc/init.d/mysql start

[root@node04 Downloads]# /etc/init.d/mysql start
Starting MySQL SUCCESS!

 

12.进入mysql 

[root@node04 Downloads]# mysql
