mysql安装方法一

4.检查系统是否安装有mysql的安装包，如果有使用rpm -e 移除

[root@OperationsAnalysis ~]# rpm -qa| grep mysql

或者

1	[root@localhost ~]# rpm -qa | grep -i mysql

2	mysql-libs-5.1.66-2.el6_3.x86_64

3	[root@localhost ~]# yum -y remove mysql-libs*

5.下载mysql5.6的安装包，并上传到服务器上

[root@OperationsAnalysis mysql]# ll
total 236180
-rw-r--r-- 1 root root 20278972 Sep 22 15:41 MySQL-client-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root  3529244 Sep 22 15:40 MySQL-devel-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root 92246408 Sep 22 15:44 MySQL-embedded-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root 61732192 Sep 22 15:42 MySQL-server-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root  2101912 Sep 22 15:42 MySQL-shared-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root  2299648 Sep 22 15:40 MySQL-shared-compat-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root 59644132 Sep 22 15:40 MySQL-test-5.6.31-1.el7.x86_64.rpm

6.安装mysql 的安装包

[root@OperationsAnalysis mysql]# rpm -ivh MySQL-server-5.6.31-1.el7.x86_64.rpm 
[root@OperationsAnalysis mysql]# rpm -ivh MySQL-devel-5.6.31-1.el7.x86_64.rpm 
[root@OperationsAnalysis mysql]# rpm -ivh MySQL-client-5.6.31-1.el7.x86_64.rpm

rpm安装默认目录：
数据文件：/var/lib/mysql/
配置文件模板：/usr/share/mysql
mysql客户端工具目录：/usr/bin
日志目录：/var/log/
pid，sock文件目录：/tmp/

一般配置文件会放置在/etc下
