cd /usr/local/wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.21-linux-glibc2.12-x86_64.tar.gztar xzvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gzmv mysql-5.7.21-linux-glibc2.12-x86_64 mysql

2. Initializing MySQL Basic environment information

vim /etc/profilePATH=/home/mysql/bin:/home/mysql/lib:$PATHexport PATHexport MYSQL_HOME="/usr/local/mysql"export ms="/usr/local/mysql"

3. Initializing the configuration instance configuration file

mkdir -p /usr/local/mysql/data/mcdbvi /usr/local/mysql/data/mcdb/my.cnf

[client]port = 3310socket = /usr/local/mysql/data/mcdb/mysql.sock[mysql]no-auto-rehash[mysqld]user = mysqlport = 3310socket = /usr/local/mysql/data/mcdb/mysql.sockbasedir = /usr/local/mysqldatadir = /usr/local/mysql/datapid-file = /usr/local/mysql/data/mcdb/mysql.pidrelay-log = /usr/local/mysql/data/mcdb/relay-binrelay-log-info-file = /usr/local/mysql/data/mcdb/relay-log.infoserver-id = 12[mysqld_safe]log-error = /usr/local/mysql/data/mcdb/mysql.errpid-file = /usr/local/mysql/data/mcdb/mysql.pid

4. Create a new user

groupadd mysqluseradd mysql -g mysqlchown mysql:mysql /usr/loca/mysql -R

5. Initializing MySQL instance
mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/mcdb --user=mysql --ldata=/usr/local/mysql
Get the password from the last line of the return message, for a chestnut:
Yulta1lw*uwf

6. Start the instance MySQL
mysqld_safe --defaults-file=/usr/local/mysql/data/mcdb/my.cnf --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/mcdb &

7. Log in to MySQL
mysql -uroot -pyUlta1lw*uwF -S /usr/local/mysql/data/mcdb/mysql.sock

8. Set the password

mysql> SET PASSWORD = PASSWORD(‘sonyw320‘); mysql> flush privileges;
