# rpm -ivh MySQL-client-5.6.20-1.sles11.x86_64.rpm
# rpm -ivh MySQL-devel-5.6.20-1.sles11.x86_64.rpm
# rpm -ivh MySQL-shared-5.6.20-1.sles11.x86_64.rpm

3. view the MySQL Service

# /etc/init.d/mysql status

The MySQL service is not started.

4. Start the MySQL Service

# /etc/init.d/mysql start
redirecting to systemctl start mysql

An error is reported, and the MySQL service cannot be started.

Use systemctl

# systemctl start mysql.service

The following error is still reported:
Failed to issue method call: Unit mysql. service failed to load: No such file or directory. See system logs and 'systemctl status mysql. service' for details.

5. Solution

# systemctl enable mysql.service

6. Start MySQL again

# systemctl start mysql
# ps -ef | grep mysql
root     27930     1  0 16:30 ?        00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/173-168-58-139.pid
mysql    28045 27930  0 16:30 ?        00:00:00 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/173-168-58-139.err --pid-file=/var/lib/mysql/173-168-58-139.pid
root     28074 25545  0 16:30 pts/1    00:00:00 grep --color=auto mysql

It can be seen that MySQL is running normally.
