MySQL5.7.18 for Linux7.2如何实现二进制安装
这篇文章主要为大家展示了"MySQL5.7.18 for Linux7.2如何实现二进制安装"，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下"MySQL5.7.18 for Linux7.2如何实现二进制安装"这篇文章吧。
具体的做法如下：
1、下载二进制软件包：
mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
2、添加MySQL用户和组：
[root@localhost ~]# userdel mysql （因为是新系统，所以就把现有的MySQL用户给删除了）
[root@localhost ~]# groupadd mysql
[root@localhost ~]# useradd -g mysql mysql
[root@localhost ~]# passwd mysql （MySQL密码要设置的复杂一点，或者在创建用户的时候设置不让登陆系统）
3、创建安装MySQL目标，并解压软件到指定目录
[root@localhost ~]# mkdir -p /mysql/data
[root@localhost ~]# chown -R mysql.mysql /mysql
[root@localhost ~]# tar zxvf mysql-5.7.18-linux-glibc2.5-x86_64 -C /mysql
[root@localhost ~]# cd /mysql
[root@localhost ~]# mv mysql-5.7.18-linux-glibc2.5-x86_64/ mysql5718
[root@localhost ~]# chown -R mysql.mysql /mysql
4、切换MySQL用户，并初始化数据库
[root@localhost ~]# su - mysql
[mysql@localhost ~]$ /mysql/mysql5718/bin/mysqld --initialize --user=mysql --basedir=/mysql/mysql5718/ --datadir=/mysql/data/
-----注意，初始化数据库会生成登录MySQL数据库的root密码，一定要记住，一会登录数据库要用
5、编辑my.cnf配置文件，启动数据库
[mysql@localhost ~]$ vim my.cnf （该配置文件仅供参考）

default_character_set = utf8
[mysql]

[mysql@localhost ~]$ /mysql/mysql5718/bin/mysqld_safe --defaults-file=/mysql/data/my.cnf --user=mysql &
6、进入数据库检查：
[mysql@localhost ~]$ /mysql/mysql5718/bin/mysql -u root -p --socket=/mysql/data/mysql.sock
Enter password:
