Binary deployment is relatively simple. You can go to mysql official website without installing dependent environment download MySQL binary package. Or through the link of my network disk download , there are auto deployment scripts in the network disk link.

Note: the latest MySQL version 8.0 is completely consistent with the deployment process of this version 5.7, except that the binary package files used are different.

1. Uninstall mariadb

[root@mysql01 ~]# yum -y erase mariadb
[root@mysql01 ~]# rpm -e qt-mysql-4.8.7-2.el7.x86_64 --nodeps

2. Deploy mysql 5.7

[root@mysql01 src]# tar zxf mysql-5.7.28-linux-glibc2.12-x86_64.tar.gz 
[root@mysql01 src]# mv mysql-5.7.28-linux-glibc2.12-x86_64 /usr/local/mysql
[root@mysql01 src]#  ln -sf /usr/local/mysql/bin/* /usr/local/bin/

3. Edit the configuration file and initialize MySQL

[root@mysql01 src]# rm -rf /etc/my.cnf
[root@mysql01 src]# vim /etc/my.cnf      #Edit MySQL main profile
[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
pid-file=/usr/local/mysql/data/mysqld.pid
log-error=/usr/local/mysql/data/mysql.err
socket=/tmp/mysql.sock
[client]
socket=/tmp/mysql.sock
#Create the required directory and users and change the owner
[root@mysql01 src]#  mkdir /usr/local/mysql/data
[root@mysql01 src]# useradd -M -s /sbin/nologin mysql
[root@mysql01 src]# chown -R mysql.mysql /usr/local/mysql/
#Initialize MySQL
[root@mysql01 src]# mysqld --initialize --user mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data
#Add as system service
[root@mysql01 src]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@mysql01 src]# chkconfig --add mysqld
#Start and set to start automatically
[root@mysql01 src]# systemctl enable mysqld
[root@mysql01 src]# systemctl start mysqld
#Make sure port 3306 is listening
[root@mysql01 src]# netstat -anpt | grep 3306
tcp6       0      0 :::3306                 :::*                    LISTEN      2589/mysqld         

4. Modify the initial password of MySQL root

#Get the initial password of root
[root@mysql01 src]# mysqlpwd=`cat /usr/local/mysql/data/mysql.err | grep password |awk -F'root@localhost: ' '{print $2}'`
#Reset password to 123.com
[root@mysql01 src]# mysql -uroot -p${mysqlpwd} -e 'alter user root@localhost identified by "123.com"' --connect-expired-password
#Login test with new password
[root@mysql01 src]# mysql -uroot -p123.com
#Additional: help command in MySQL
mysql> help show;          #This command can check the syntax of all show commands and help + any command word
