1、下载软件安装包
服务器：118.190.152.60 mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz
2、创建mysql用户
useradd mysql passwd mysql_123456 创建用户使其不允许登录： 请注意要在root用户下进行 修改已经存在的用户使其不允许登录： usermod -s /sbin/nologin 新建用户不允许登录： useradd -s /sbin/nologin
3、创建mysql5.7版本需要的目录
mkdir -pv /data/mysql/mysql9571/{conf,data,logs,run,tmp}
4、创建MySQL5.7需要的配置文件
[root@iZm5eckxl2tqyk76wy33pkZ ~

[root@iZm5eckxl2tqyk76wy33pkZ conf
]

[root@iZm5eckxl2tqyk76wy33pkZ conf
]
解压mysql二进制包 [root@VM_0_8_centos opt]# tar -zxvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz 修改目录权限 chown -R mysql.mysql /opt/mysql-5.7.11-linux-glibc2.5-x86_64/ chown -R mysql.mysql /data/mysql/mysql9571/ 配置环境变量 echo ‘export PATH=/opt/mysql-5.7.11-linux-glibc2.5-x86_64/bin:$PATH’ >> /etc/profile source /etc/profile
5、初始化mysql5.7版本数据库

查看my9571.cnf的权限
[root@ttlsa ~]# ls -l my9571.cnf -rwxrwxrwx 1 root root 4878 Jul 30 11:31 my9571.cnf 权限777，任何一个用户都可以改my9571.cnf，存在很大的安全隐患. 修复MySQL问题 [root@VM_0_8_centos conf]# chmod 644 my9571.cnf
6、启动mysql5.7版本数据库
[root@iZm5eckxl2tqyk76wy33pkZ mysql-5.7.11-linux-glibc2.5-x86_64
]
[root@iZm5eckxl2tqyk76wy33pkZ conf
]
注意这样不是后台进程启动，终端断开数据库会kill掉。 停止mysql的方法 [root@VM_0_2_centos logs]# mysqladmin -uroot -p shutdown -S /data/mysql/9571/run/mysql9571.sock Enter password:
7、登陆数据库
[root@iZm5eckxl2tqyk76wy33pkZ mysql-5.7.11-linux-glibc2.5-x86_64
