Linux下安装MySQL5.7（使用rpm安装）

首先在 /usr/local/目录下新建一个文件夹 mysql
切换到mysql目录下

（1）下载

**//下载安装包**
[root@localhost mysql]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22-1.el7.x86_64.rpm-bundle.tar

//**解压在mysql文件夹内**
[root@localhost mysql]# tar -xf mysql-5.7.22-1.el7.x86_64.rpm-bundle.tar 

//**安装依赖包**
[root@localhost mysql]# yum -y install make gcc-c++ cmake bison-devel ncurses-devel libaio-devel net-tools

**由于Centos7开始自带的数据库是mariadb，所以需要卸载系统中的mariadb组件，才能安装mysql的组件**
[root@localhost mysql]# rpm -qa | grep mariadb
mariadb-libs-5.5.68-1.el7.x86_64
[root@localhost mysql]# yum -y remove mariadb-libs                  //卸载

（2）安装

[root@localhost mysql]# rpm -ivh mysql-community-common-5.7.22-1.el7.x86_64.rpm

（3）启动

[root@localhost mysql]# systemctl start mysqld
[root@localhost mysql]# systemctl enable mysqld
[root@localhost mysql]# systemctl status mysqld

（4）查找密码并登录

[root@localhost mysql]# grep "password" /var/log/mysqld.log    // 前往日志文件查找临时密码
2022-01-17T14:15:30.044799Z 1 [Note] A temporary password is generated for root@localhost: VihNdp7u+ff;
//密码用引号包住，因为有特殊符号
[root@localhost mysql]# mysql -uroot -p"VihNdp7u+ff;"

（5）重新设置密码格式

mysql> set global validate_password_policy=0;
Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password_length=1;
Query OK, 0 rows affected (0.00 sec)

mysql> set password for root@localhost=password('root');         //设置密码
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;             //刷新
Query OK, 0 rows affected (0.00 sec)

mysql> exit           //退出
Bye

（6）用新密码重新登录

[root@localhost mysql]# mysql -uroot -proot         
mysql: [Warning] Using a password on the command line interface can be insecure.
