8988:M 25 Jun 11:24:31.321 # 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.

指定配置启动

redis-server /etc/redis.conf 

redis-server ./redis.conf

后台运行

[root ~]#redis-server /etc/redis.conf --daemonize yes
[root ~]#
[root ~]#ps -ef | grep redis
root     20568     1  0 11:29 ?        00:00:00 redis-server *:6379
root     23088  8695  0 11:29 pts/0    00:00:00 grep --color=auto redis
[root ~]#

关闭redis

redis-cli shutdown

redis客户端

启动redis命令行

[root ~]#redis-cli -h 127.0.0.1 -p 6379
127.0.0.1:6379> ping
PONG

这里如果不指定-h 和-p的默认-h是127.0.0.1 -p是6379
我们除了在本机登陆也可以在其它机器远程访问：

远程登录redis

需要修改配置文件/etc/redis.conf，注释如下一行

bind 127.0.0.1

类似于mongo，默认监听的是本机，可以在nestat -anlp | grep redis中看到.

[root ~]#netstat -anlp | grep redis
tcp        0      0 0.0.0.0:6379            0.0.0.0:*               LISTEN      26444/redis-server
tcp6       0      0 :::6379                 :::*                    LISTEN      26444/redis-server
[root ~]#

修改配置：

protected-mode no

这个特性禁止外部访问redis ，加强redis的安全性。
放通端口：

[root ~]#firewall-cmd --zone=public --add-port=6379/tcp --permanent
success
[root ~]#
[root ~]#firewall-cmd --reload
success

在外部机器访问：

coder52@52coder ~ % redis-cli -h 192.168.31.103 -p 6379
192.168.31.103:6379> ping
PONG
192.168.31.103:6379>
