Install mysql (rpm version) on Linux system

RPM (Red-Hat Package Manager) RPM package manager is a tool used by Red Hat Linux to manage and install software.

1. Check whether the MySQL database is installed in the current system

rpm -qa                    查询当前系统中安装的所有软件
rpm -qa | grep mysql       查询当前系统中安装的名称带mysql的软件
rpm -qa | grep mariadb     查询当前系统中安装的名称带mariadb的软件

Note: If the MySQL database is already installed in the current system, the installation will fail. Cento57 comes with mariadb and MySQL

Database conflict

The system’s own database

rpm -e --nodeps 软件名称        卸载软件

rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64

2. Upload the mysql installation package to Linux and decompress it

Here I uploaded it to the opt directory, created a mysql folder, and uploaded it to it.

 Unzip the file and enter the command in the current folder

tar -zxvf mysql-5.7.25-1.el7.x86_64.rpm-bundle.tar.gz

After decompression, you will get 6 rpm installation package files.

3. Install rpm packages in order

rpm -ivh mysql-community-common-5.7.25-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.25-1.el7.x86_64.rpm

rpm -ivh mysql-community-devel-5.7.25-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-compat-5.7.25-1.el7.x86_64.rpm

rpm -ivh mysql-community-client-5.7.25-1.el7.x86_64.rpm

yum install net-tools

rpm -ivh mysql-community-server-5.7.25-1.el7.x86_64.rpm

Note: If the installation process prompts that the net-tools dependency is missing, use yum to install it.

Existing software and system kernel can be upgraded through commands:

yum update

4. Start mysql

systemctl status mysqld       查看mysql服务状态
systemctl start mysqld        启动mysql服务

 

5. Set up auto-start at boot

systemctl enable mysqld

6. View started services

netstat -tunlp                查看已经启动的服务

netstat -tunlp | grep mysql     
ps -ef | grep mysql            查看mysql进程

7. View temporary password

cat /var/log/mysqld.log             查看文件内容

cat /var/log/mysqld.log | grep password        查看指定文件内容

8. Log in to mysql and enter the temporary password

mysql -uroot -p

9. Change password

set global validate_password_length=4;        设置密码长度最低位数

set global validate_password_policy=LOW;      设置密码安全等级低，便于密码可以修改成root

set password = password('root');              设置密码为root

 

10. Enable access permissions

grant all on *.* to 'root'@'%' identified by 'root';

 

11. Refresh files

flush privileges;

12. Log in to the database again

mysql -uroot -proot

13. View the database

show databases;

14. Remote connection, turn off the firewall before connecting

systemctl disable firewalld
