Linux CentOS installation and configuration of MySQL database
Nothing to say, just straight to the front.
install mysql database
a) Download the mysql source installation package: wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
b) Install mysql source: yum localinstall mysql57-community-release-el7-8.noarch.rpm
If complete! appears at the end, the MySQL source installation is complete
c) Check whether the installation is complete: yum repolist enabled | grep "mysql.*-community.*"
d) Install mysql: yum install mysql-community-server
If Complete! appears at the end, the MySQL installation is complete
e) Set to start the mysql service: systemctl enable mysqld
f) Check the installed mysql version: rpm -aq | grep -i mysql
g) Start the MySQL service: systemctl restart mysqld
h) View MySQL initial password: grep 'A temporary password' /var/log/mysqld.log
i) Change MySQL password: mysqladmin -u root -p 'old password' password 'new password'
There is a problem with changing the password here, and the change fails because the password is too simple. There are two workarounds:
Method 1: Make the password complex (this is the most direct method)
Method 2: Turn off mysql password strength verification (validate_password)
Edit the configuration file: vim /etc/my.cnf, add such a line validate_password=off
编辑后重启mysql服务：systemctl restart mysqld
j)设置mysql能够远程访问:
登录进MySQL：mysql -uroot -p密码
增加一个用户给予访问权限：grant all privileges on *.* to 'root'@'ip地址' identified by '密码' with grant option; //可将ip改为%%,表示开启所有的
OK，我本地连接试下。
好了，到这里就结束了，祝大家别出BUG。
