1. Download Mysql package, here I use the mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz;
2. Use a script to create Mysql, with specific reference to https://blog.csdn.net/zfyy1989/article/details/88873438
Problems encountered:
1) reset the root password
1.1, vi /etc/my.cnf
add parameters to skip-grant-tables to save and exit [mysqld] Under;
1.2 mysql command line and no password to enter the password:
update user set authentication_string=password('root') where user='root';
1.3 The parameter commented out and restart the service:
2) Mysql default can not remotely connect, you need to modify:
2.1 update user set host = ’%’ where user = ’root’;
3) navicat remote connections newspaper Can not connect to MySQL server on '' (10038)
We need to modify the firewall:
Reload
firewall-cmd --reload
view
firewall-cmd --zone = public --query- port = 3306 / tcp
delete
firewall-cmd --zone = public --remove- port = 3306 / tcp --permanent
firewall-cmd --zone = public --add-port = 3306 / tcp --permanent (--permanent permanent, this parameter is not restarted after the failure)
firewall-cmd --zone=public --add-port=1000-2000/tcp --permanent
