[root@localhost ~]# rpm -q libaio
libaio-0.3.109-13.el7.x86_64

2. Use wget command to download mysql-5.7.24 package

[root@localhost mysql]# chown -R mysql:mysql ./

8. Initialize mysql database (set up default database and table). The command is as follows:

[root@localhost mysql]# ./bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize

9. Open mysqld service. The command is as follows

[root@localhost mysql]# vim /etc/my.cnf
[mysqld]
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
[mysqld_safe]
log-error=/usr/local/mysql/data/mysql.log

[root@localhost mysql]# ls -l /etc/init.d/mysqld
-rwxr-xr-x 1 root root 10576 12 month  7 16:12 /etc/init.d/mysqld

[root@localhost mysql]# ./bin/mysqladmin -u root -p'e9iIEYBa9t!f' password '123456'

13. Add mysql command to the system command execution path for easy use.

[root@localhost mysql]# ln -s /usr/local/mysql/bin/* /usr/local/bin/
[root@localhost mysql]# cd
[root@localhost ~]# mysql -u root -p123456
