1. Check whether the network port is open
Open the command line and enter: telnet 192.168.1.106 6379
(If it returns "telnet is not an internal or external command", see: What to do if telnet is not an internal or external command )
If it is found that the port is not open:
a. Open the port method in CentOS 7.x:
~:# firewall-cmd --query-port=6379/tcp
~:# firewall-cmd --add-port=6379/tcp
~:# firewall-cmd --query-port=6379/tcp
b. Open the port method in CentOs 6.x:
~:# /sbin/iptables -I INPUT -p tcp --dport 6379 -j DROP write modification
~:# /etc/init.d/iptables save save changes
~:# service iptables restart restart the firewall, the modification will take effect
2. Open the "redis installation directory/redis.conf" file,
a. Find the line "bind 127.0.0.1" and comment it with #
b. Find the line "# requirepass", remove the # comment, and add the password you set
3. Restart redis
~:# src/redis-server redis.conf
