安装前查看有无旧mysql文件影响，若有删除
[root@localhost ~]# find / -name mysql /usr/lib64/mysql /usr/share/mysql [root@localhost ~]# rm -rf /usr/lib64/mysql /usr/share/mysql [root@localhost ~]# find / -name mysql
安装文件传输工具
[root@localhost ~]# yum install -y lrzsz
已经在在电脑本地下载好安装包，用文件传输工具传到虚拟机，/usr/local/src下
[root@localhost ~]# rz rz waiting to receive. zmodem trl+C ȡ 100% 638679 KB 15577 KB/s 00:00:41 0 Errorsc2.5-x86_64.tar.gz... [root@localhost src]# ls mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
解压，并移命令到/usr/local/mysql目录下
[root@localhost src]# tar -zxf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz [root@localhost src]# mv mysql-5.7.17-linux-glibc2.5-x86_64 /usr/local/mysql
创建mysql数据库
[root@localhost mysql]# mkdir -p /data/mysql
创建mysql用户、组、目录
[root@localhost mysql]# groupadd mysql
[root@localhost mysql]# useradd -s /sbin/nologin -g mysql -d /usr/local/mysql/ mysql #指定shell，组，目录
更改所需目录的属性
[root@localhost mysql]# chown -R mysql:mysql /usr/local/mysql/
[root@localhost mysql]# chown -R mysql:mysql /data/mysql/
