MySQL 5.7安装最佳实践
1、环境准备
OS: CentOS Linux release 7.4.1708 (Core) for VMware
MySQL: mysql-5.7.24-linux-glibc2.12-x86_64
2、安装包准备，依赖检查
建议从官方下载，下载地址为：https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
也可以在linux系统中用wget命令下载：
[root@localhost ~]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
[root@localhost ~]# md5sum mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
[root@localhost ~]# mkdir /opt/mysql
[root@localhost ~]# tar -zxvf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz -C /opt/mysql/
[root@localhost ~]# cd /usr/local
[root@localhost local]# ln -s /opt/mysql/mysql-5.7.24-linux-glibc2.12-x86_64/ mysql
[root@localhost local]# ldd mysql/bin/mysqld

说明：在 ldd 命令打印的结果中，“=>”左边的表示该程序需要连接的共享库之 so 名称，右边表示由 Linux 的共享库系统找到的对应的共享库在文件系统中的具体位置，“=>”右边有值就可以了。
3、建立用户，目录规划，my.cnf文件配置
[root@localhost local]# groupadd mysql
[root@localhost local]# useradd -g mysql -d /usr/local/mysql -s /sbin/nologin -MN mysql
[root@localhost local]# chown -R mysql:mysql mysql
[root@localhost local]# mkdir -p /data/mysql/mysql3306/{data,tmp,logs}
[root@localhost local]# chown -R mysql:mysql /data/
[root@localhost local]# vim /etc/my.cnf
