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

CentOS 7下使用RPM安装mysql5.7.13,centosmysql5.7.13

0、环境

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

[[email protected] ~]# rpm -qa|grep mariadb
mariadb-libs-5.5.44-2.el7.centos.x86_64
[[email protected] ~]# 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)。

复制代码
代码如下:[[email protected]
~]# wget

然后解压

[[email protected] ~]# ls
mysql-5.7.13-1.el7.x86_64.rpm-bundle.tar
[[email protected] ~]# tar xvf mysql-5.7.13-1.el7.x86_64.rpm-bundle.tar
mysql-community-test-5.7.13-1.el7.x86_64.rpm
mysql-community-embedded-5.7.13-1.el7.x86_64.rpm
mysql-community-embedded-compat-5.7.13-1.el7.x86_64.rpm
mysql-community-server-5.7.13-1.el7.x86_64.rpm
mysql-community-client-5.7.13-1.el7.x86_64.rpm
mysql-community-common-5.7.13-1.el7.x86_64.rpm
mysql-community-server-minimal-5.7.13-1.el7.x86_64.rpm
mysql-community-embedded-devel-5.7.13-1.el7.x86_64.rpm
mysql-community-devel-5.7.13-1.el7.x86_64.rpm
mysql-community-libs-compat-5.7.13-1.el7.x86_64.rpm
mysql-community-libs-5.7.13-1.el7.x86_64.rpm
mysql-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

[[email protected] ~]# rpm -ivh mysql-community-common-5.7.13-1.el7.x86_64.rpm
[[email protected] ~]# rpm -ivh mysql-community-libs-5.7.13-1.el7.x86_64.rpm
[[email protected] ~]# rpm -ivh mysql-community-client-5.7.13-1.el7.x86_64.rpm
[[email protected] ~]# 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

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。

[[email protected] ~]# systemctl start mysqld
[[email protected] ~]# mysql -uroot -p
Enter password:

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。
