3. 修改端口，
编辑/etc/my.cnf文件，早期版本有可能是my.conf文件名，增加端口参数，并且设定端口，注意该端口未被使用，保存退出。
[root@test etc]# vi my.cnf
[mysqld]
port=3506
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
"my.cnf" 11l, 261c written
[root@test etc]#
4. 重新启动mysql
[root@test ~]#systemctl restart mysqld
5.再次登录后检查端口已修改为’3506’.
[root@test etc]# mysql -u root -p
