10 Add system path
vim /etc/profile
Add: export PATH=/usr/local/mysql/bin:$PATH as follows:
source /etc/profile
11 Configure mysql to start automatically
chmod 755 /etc/init.d/mysql
> # chkconfig --add mysql
> # chkconfig --level 345 mysql on
The above is the installation tutorial of Mysql 5.7.13 in linux environment,
-View mysql status
#service mysql status
[root@oceadatabase ~]# ps -ef|grep mysqld
root 5748 1 0 20:41 pts/1 00:00:00 /bin/sh /mysql/bin/mysqld_safe --datadir=/mysql/data --pid-file=/mysql/data/oceadatabase.pid

-Stop mysql
#service mysql stop
-Start mysql
#service mysql start
Create an alias to connect to the mysql database
[root@oceadatabase ~]# alias mysql=‘mysql -uroot -pmysql#123’
ch
A way to add automatic start of the system
chmod 755 /etc/init.d/sh file
> # chkconfig --add sh file
> # chkconfig --level 345 mysql on
