Centos6 通过RPM部署Mysql5.7

1.下载对应版本的mysql  rpm安装包

本人用的是centos6.8 64位系统，[mysql安装包官方下载地址 ][mysql]

2.安装mysql5.7

###    安装步骤如下 ###

①.查看系统已经安装过其他版本的mysql

yum list installed | grep mysql  查看是否有安装过mysql  通过yum remove 卸载  
  
  
    rpm -qa | grep -i mysql 查看是否有rpm包  通过rpm -e --nodeps移除

②. 安装依赖(Mysql5.7 需要安装)

yum -y install numactl

③.安装mysql rpm包

只需要安装其中的四个

rpm -ivh  mysql-community-common-5.7.19-1.el6.x86_64.rpm
        rpm -ivh mysql-community-libs-5.7.19-1.el6.x86_64.rpm
        rpm -ivh mysql-community-client-5.7.19-1.el6.x86_64.rpm
        rpm -ivh  mysql-community-server-5.7.19-1.el6.x86_64.rpm

④.修改mysql配置文件my.cnf

[client]  
        default-character-set=utf8
      
        [mysqld]  
        character_set_server=utf8

⑤.启动mysql并查看mysql初始化的随机密码

service mysqld start

grep 'temporary password' /var/log/mysqld.log

![Center][]

⑥.修改初始密码

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';

需要注意是的 5.7中 设置的密码安全度有点高，需要有大小写字母数字特殊字符，可以更改后，再去my.cnf中加入validate\_password=OFF 去除密码安全度验证。

最后附上 自用的生产环境Mysql配置(部分配置用于主从同步可以忽略，具体参数根据服务器配置设置)
