啟動時報的警告：
1、Warning: no config file specified, using the default config. In order to specify a config file use ./src/redis-server /path/to/redis.conf
就因為這個原因，無法連接到遠程redis：Unable to connect to 192.168.163.131:6379
解決：
[root@cent7-zuoys src]# ./redis-server ../redis.conf
2、
WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
解決：
編輯/etc/sysctl.conf ，改vm.overcommit_memory=1，然后sysctl -p 使配置文件生效
3、The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
解決：
在/etc/sysctl.conf中添加:net.core.somaxconn = 2048，然后在終端中執行sysctl -p
4、
you have Transparent Huge Pages (THP) support enabled in your kernel.?This will create latency and memory usage issues with Redis.?To fix thisissue run the?command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root,?and add it to your /etc/rc.local in order to retain thesetting after a reboot.?Redis must be restarted after THP is disabled.
解決：
臨時解決方法： echo never > /sys/kernel/mm/transparent_hugepage/enabled。 永久解決方法： 將其寫入/etc/rc.local文件中。

1、注釋掉 bind 127.0.0.1，即可讓所有ip訪問 2、protected-mode no
