      CentOS 7 RPM 安装 MySQL5.7


      本文操作系统: CentOS 7.2.1511 x86_64
      MySQL版本: 5.7.13

      1、卸载系统自带的 mariadb-lib

      [root@centos-linux ~]# rpm -qa|grep mariadbmariadb-libs-5.5.44-2.el7.centos.x86_64[root@centos-linux ~]# rpm -e mariadb-libs-5.5.44-2.el7.centos.x86_64 --nodeps

      #### 2、下载 rpm 安装包

      去官网找到最新的 rpm 集合包。现在最新的是mysql-5.7.13-1.el7.x86_64.rpm-bundle.tar

      复制其下载地址,在服务器下载 (或者本地下载了上传至服务器)。

      [root@centos-linux ~]# wget http://www.1click-soft.com/tfgjylgw/get/Downloads/MySQL-5.7/mysql-5.7.13-1.el7.x86_64.rpm-bundle.tar

      然后解压

      [root@centos-linux ~]# lsmysql-5.7.13-1.el7.x86_64.rpm-bundle.tar[root@centos-linux ~]# tar xvf mysql-5.7.13-1.el7.x86_64.rpm-bundle.tarmysql-community-test-5.7.13-1.el7.x86_64.rpmmysql-community-embedded-5.7.13-1.el7.x86_64.rpmmysql-community-embedded-compat-5.7.13-1.el7.x86_64.rpmmysql-community-server-5.7.13-1.el7.x86_64.rpmmysql-community-client-5.7.13-1.el7.x86_64.rpmmysql-community-common-5.7.13-1.el7.x86_64.rpmmysql-community-server-minimal-5.7.13-1.el7.x86_64.rpmmysql-community-embedded-devel-5.7.13-1.el7.x86_64.rpmmysql-community-devel-5.7.13-1.el7.x86_64.rpmmysql-community-libs-compat-5.7.13-1.el7.x86_64.rpmmysql-community-libs-5.7.13-1.el7.x86_64.rpmmysql-community-minimal-debuginfo-5.7.13-1.el7.x86_64.rpm

      3、安装

      依次执行(几个包有依赖关系,所以执行有先后)下面命令安装

      [root@centos-linux ~]# rpm -ivh mysql-community-common-5.7.13-1.el7.x86_64.rpm[root@centos-linux ~]# rpm -ivh mysql-community-libs-5.7.13-1.el7.x86_64.rpm[root@centos-linux ~]# rpm -ivh mysql-community-client-5.7.13-1.el7.x86_64.rpm[root@centos-linux ~]# rpm -ivh mysql-community-server-5.7.13-1.el7.x86_64.rpm

      4、数据库初始化

      在 *nix 系统中,为了保证数据库目录为与文件的所有者为 mysql 登陆用户,如果你是以 root 身份运行 mysql 服务,需要执行下面的命令初始化

      mysqld --initialize --user=mysql

      如果是以 mysql 身份运行,则可以去掉--user选项。

      另外--initialize选项默认以“安全”模式来初始化,则会为 root 用户生成一个密码并将该密码标记为过期,登陆后你需要设置一个新的密码,而使用--initialize-insecure命令则不使用安全模式,则不会为 root 用户生成一个密码。

      这里演示使用的--initialize初始化的,会生成一个 root 账户密码,密码在log文件里

      [root@centos-linux ~]# cat /var/log/mysqld.log2016-07-16T07:56:38.282824Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).2016-07-16T07:56:38.422114Z 0 [Warning] InnoDB: New log files created, LSN=457902016-07-16T07:56:38.449315Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.2016-07-16T07:56:38.457910Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: d3261dbf-4b2a-11e6-86ef-001c4260563f.2016-07-16T07:56:38.458976Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.2016-07-16T07:56:38.459524Z 1 [Note] A temporary password is generated for root@localhost: hm9dKgzQdm:W

      上图里的最后一行则给出了生成的密码,现在就可以启动数据库了,然后使用上面的密码登陆。

      [root@centos-linux ~]# systemctl start mysqld[root@centos-linux ~]# mysql -uroot -pEnter password:Welcome to the MySQL monitor.

Type '\c' to clear the current input statement.mysql>

      5、修改 root 密码

      该密码被标记为过期了,如果想正常使用还需要修改密码

      mysql> show databases;ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

      以前的password()函数将会被抛弃,官方建议使用下面的命令来修改密码

      mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';

      同时,如果你设置的密码过于简单也会报错。

      mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123';ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

      具体关于设置密码的规则,可以看这一篇文章。

      这里我们注意设置密码 长度要大于8,同时要有数字,大小写,特殊字符。
