0、环境

本文操作系统: CentOS 7.2.1511 x86\_64  
MySQL 版本: 5.7.16

1、卸载系统自带的 mariadb-lib

\[root@centos-linux ~\]\# rpm -qa|grep mariadb  
mariadb-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mysql5.7.16 rpm安装包，官网最新的mysql安装包是mysql-5.7.16-1.el7.x86\_64.rpm-bundle.tar下载地址

\[root@centos-linux ~\]\# wget [http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.16-1.el7.x86\_64.rpm-bundle.tar][http_dev.mysql.com_get_Downloads_MySQL-5.7_mysql-5.7.16-1.el7.x86_64.rpm-bundle.tar]

然后解压  
　\[root@linux\_node\_1 src\]\# tar -xvf mysql-5.7.16-1.el7.x86\_64.rpm-bundle.tar  
mysql-community-libs-compat-5.7.16-1.el7.x86\_64.rpm  
mysql-community-devel-5.7.16-1.el7.x86\_64.rpm  
mysql-community-minimal-debuginfo-5.7.16-1.el7.x86\_64.rpm  
mysql-community-libs-5.7.16-1.el7.x86\_64.rpm  
mysql-community-common-5.7.16-1.el7.x86\_64.rpm  
mysql-community-embedded-compat-5.7.16-1.el7.x86\_64.rpm  
mysql-community-test-5.7.16-1.el7.x86\_64.rpm  
mysql-community-embedded-devel-5.7.16-1.el7.x86\_64.rpm  
mysql-community-server-minimal-5.7.16-1.el7.x86\_64.rpm  
mysql-community-server-5.7.16-1.el7.x86\_64.rpm  
mysql-community-client-5.7.16-1.el7.x86\_64.rpm  
mysql-community-embedded-5.7.16-1.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-5.7.16-1.el7.x86\_64.rpm  
\[root@centos-linux ~\]\# rpm -ivh mysql-community-libs-5.7.16-1.el7.x86\_64.rpm  
\[root@centos-linux ~\]\# rpm -ivh mysql-community-client-5.7.16-1.el7.x86\_64.rpm  
\[root@centos-linux ~\]\# rpm -ivh mysql-community-server-5.7.16-1.el7.x86\_64.rpm  
在安装rpm -ivh mysql-community-server-5.7.16-1.el7.x86\_64.rpm的时候报错如下：  
\[root@linux\_node\_1 src\]\# rpm -ivh mysql-community-server-5.7.16-1.el7.x86\_64.rpm  
warning: mysql-community-server-5.7.16-1.el7.x86\_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY  
error: Failed dependencies:  
libaio.so.1()(64bit) is needed by mysql-community-server-5.7.16-1.el7.x86\_64  
libaio.so.1(LIBAIO\_0.1)(64bit) is needed by mysql-community-server-5.7.16-1.el7.x86\_64  
libaio.so.1(LIBAIO\_0.4)(64bit) is needed by mysql-community-server-5.7.16-1.el7.x86\_64  
net-tools is needed by mysql-community-server-5.7.16-1.el7.x86\_64

这个报错的意思是需要安装libaio包和net-tools包：可以yum安装一下，安装 libaio-0.3.107-10.el6.x86\_64.rpm，下载地址：

wget [http://mirror.centos.org/centos/6/os/x86\_64/Packages/libaio-0.3.107-10.el6.x86\_64.rpm][http_mirror.centos.org_centos_6_os_x86_64_Packages_libaio-0.3.107-10.el6.x86_64.rpm]  
然后yum安装net-tools yum install net-tools 完成之后就可以顺利安装  
4、数据库初始化

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，红色区域的就是自动生成的密码

\[root@linux\_node\_1 src\]\# cat /var/log/mysqld.log  
2016-12-07T04:41:58.028558Z 0 \[Warning\] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit\_defaults\_for\_timestamp server option (see documentation for more details).  
2016-12-07T04:41:58.315188Z 0 \[Warning\] InnoDB: New log files created, LSN=45790  
2016-12-07T04:41:58.355114Z 0 \[Warning\] InnoDB: Creating foreign key constraint system tables.  
2016-12-07T04:41:58.418448Z 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: 7cc98831-bc37-11e6-a263-000c29f902dc.  
2016-12-07T04:41:58.419935Z 0 \[Warning\] Gtid table is not ready to be used. Table 'mysql.gtid\_executed' cannot be opened.  
2016-12-07T04:41:58.420558Z 1 \[Note\] A temporary password is generated for root@localhost: )1r3gi,hjgQa

现在启动mysql数据库systemctl start mysqld.service

\[root@linux\_node\_1 src\]\# systemctl start mysqld.service

\[root@linux\_node\_1 src\]\# mysql -uroot -p

Enter password:  
Welcome to the MySQL monitor. Commands end with ; or \\g.  
Your MySQL connection id is 2  
Server version: 5.7.16

5、修改密码

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

语法：mysql> GRANT <权限> ON <库>.<表> TO ‘用户’@’主机名’ identified by “密码”;

mysql> grant select,insert,update,delete on book.\* to test2@localhost identified by “abc”; \#增加test2用户，密码为abc。并只能在localhost这台主机上登录，并且只能访问book这个库中的表，具有查询，插入，更新，删除权限；
