CentOS7安装mysql5.7解压缩版简明教程

2019-01-16 22:14:18丽君

本文实例讲述了CentOS7安装mysql5.7解压缩版的方法。，具体如下：

1.下载安装包

http://dev.mysql.com/downloads/mysql/#downloads
推荐下载通用安装方法的TAR包

2.检查库文件是否存在，如有删除。

[root@localhost Desktop]$ rpm -qa | grep mysql mysql-libs-5.1.52-1.el6_0.1.x86_64 [root@localhost ~]$ rpm -e mysql-libs-5.1.52.x86_64 --nodeps [root@localhost ~]$

3.检查mysql组和用户是否存在，如无创建。

[root@localhost ~]$ cat /etc/group | grep mysql mysql:x:490: [root@localhost ~]$ cat /etc/passwd | grep mysql mysql:x:496:490::/home/mysql:/bin/bash 以上为默认存在的情况，如无，执行添加命令： [root@localhost ~]$groupadd mysql [root@localhost ~]$useradd -r -g mysql mysql //useradd -r参数表示mysql用户是系统用户，不可用于登录系统。

4.解压TAR包，更改所属的组和用户

[root@localhost ~]$ cd /usr/local/ [root@localhost local]$ tar xvf mysql-5.7.12-linux-glibc2.5-x86_64.tar [root@localhost local]$ ls -l total 1306432 -rwxr--r--. 1 root root 668866560 Jun 1 15:07 mysql-5.7.12-linux-glibc2.5-x86_64.tar -rw-r--r--. 1 7161 wheel 638960236 Mar 28 12:54 mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz -rw-r--r--. 1 7161 wheel 29903372 Mar 28 12:48 mysql-test-5.7.12-linux-glibc2.5-x86_64.tar.gz [root@localhost local]$ tar xvfz mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz [root@localhost local]$ mv mysql-5.7.12-linux-glibc2.5-x86_64 mysql [root@localhost local]$ ls -l total 1306436 drwxr-xr-x. 2 root root 4096 Dec 4 2009 bin drwxr-xr-x. 2 root root 4096 Dec 4 2009 etc drwxr-xr-x. 2 root root 4096 Dec 4 2009 games drwxr-xr-x. 2 root root 4096 Dec 4 2009 include drwxr-xr-x. 2 root root 4096 Dec 4 2009 lib drwxr-xr-x. 3 root root 4096 Dec 2 14:36 lib64 drwxr-xr-x. 2 root root 4096 Dec 4 2009 libexec drwxr-xr-x. 9 7161 wheel 4096 Mar 28 12:51 mysql -rwxr--r--. 1 root root 668866560 Jun 1 15:07 mysql-5.7.12-linux-glibc2.5-x86_64.tar -rw-r--r--. 1 7161 wheel 638960236 Mar 28 12:54 mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz -rw-r--r--. 1 7161 wheel 29903372 Mar 28 12:48 mysql-test-5.7.12-linux-glibc2.5-x86_64.tar.gz drwxr-xr-x. 2 root root 4096 Dec 4 2009 sbin drwxr-xr-x. 6 root root 4096 Dec 2 14:36 share drwxr-xr-x. 2 root root 4096 Dec 4 2009 src [root@localhost local]$ chown -R mysql mysql/ [root@localhost local]$ chgrp -R mysql mysql/ [root@localhost local]$ cd mysql/
