Linux利用rpm包安装mysql5.7.15

Mysql安装的三种模式：rpm包安装、二进制安装和源码安装三种，其中rpm包安装最为简单，本文档只讲述该安装方式

1.mysql用户创建

groupaddmysql; useradd–g mysqlmysql

2.mysql安装包的上传与解压

利用ftp工具将mysql的安装包上传

利用tar工具进行解压

3.mysql安装

可根据实际需要选择进行相应rpm包的安装，本手册主要安装server和client两个rpm包，该包以来common和libs包，具体的安装顺序如下：

4.配置文件位置及查看

安装完毕后会自动在/etc目录下面生成一个my.cnf的配置文件 cat /etc/my.cnf

5.生成的root的密码通过查看日志

根据上述的my.cnf查看知悉mysql的日志为mysqld.log，位置在/var/log/，可打开直接搜索A temporary password is generated for root@localhost:查看初始化密码，一般在日志的前几行比较考前，如下红色框即为root的初始化密码

6、启动及系统初始化

（1）启动 Service mysqld start （2）初始化

使用mysql_secure_installation进行初始化的设置mysql_secure_installation命令的地址为/usr/bin,执行如下

/usr/bin/mysql_secure_installation New password: --更换root用户密码 Re-enter new password:

Estimated strength of the password: 100

Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y

By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y—删除自带用户

Success.

Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y—是否只在mysql服务器上使用root用户登录

Success.

By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing,
