centos7源码glib包安装mysql５.7.30
ENV:
[root@lnmp ~]# uname -r

[root@lnmp ~]# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core) 安装过程：
一：上传或下载mysql５.7.30的glib安装包
下载地址：https://dev.mysql.com/downloads/mysql/
我下载的是完整包
https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.31-linux-glibc2.12-x86_64.tar
[root@lnmp ~]# cd Downloads/
[root@lnmp Downloads]# ls

mysql-5.7.30-linux-glibc2.12-x86_64.tar.gz mysql.sh二：编写mysql.sh直接使用安装脚本安装，使过程更简单
/usr/lib/systemd/system/mysqld.service 这个文件是systemctl命令所需文件，很多的文章中并没有写这一类的，我只是采用自己电脑上的文件直接套用的，效果还不错，因有英文注解，这里不解释。
mysql的安装目录为/usr/local/mysql data目录为 /usr/local/mysql/data 用户 mysql
mysql的安装设置可参考mysql官方文档进行设置，我这里只是简单操作过程。不要照搬！！！
bin/mysqld --initialize --datadir=/usr/local/mysql/data --user=mysql --basedir=/usr/local/mysql[root@lnmp Downloads]# vim mysql.sh

四：查看启动状态并使用
如需要加入开机启动列表 systemctl enable mysqld 实现开机启动
[root@lnmp mysql]# systemctl status mysqld

Bye五：修改密码并使用mysql
mysql５.7之后的版本的安全考虑，第一次进入后需重新设置密码才能进行正常操作，修改一个新的密码吧。
