    8877:M 30 Oct 14:38:25.733 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue 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 the setting after a reboot. Redis must be restarted after THP is disabled.

# 二.停止redis #

# 停止Redis命令
    redis-cli shutdown

[root@10-31-1-123 ~]# redis-cli shutdown

    6266:M 30 Oct 14:45:36.186 # Redis is now ready to exit, bye bye...
    [1]+  完成                  redis-server /usr/local/redis/redis.conf
    [root@10-31-1-123 ~]# ps -ef | grep redis
    root      6346  3051  0 14:45 pts/0    00:00:00 grep --color=auto redis

# 三.登陆redis #

备注:  
10.31.1.123 redis.conf文件，bind 为 127.0.0.1 所以可以直接用redis-cli命令来登陆，不然得使用 -h -p -a的方式登陆  
10.31.1.123这台是不能被别的主机远程登陆

10.31.1.124 redis.conf文件，bind为 10.31.1.124 不能使用redis-cli命令来登陆，只能使用 -h -p -a的方式来登陆  
10.31.1.124这台可以被别的主机远程登陆

## 3.1 登陆本机redis ##

redis-cli

测试记录:

[root@10-31-1-123 ~]# redis-cli
    127.0.0.1:6379> exit

## 3.2 登陆远程主机的redis ##

-h  主机名
    -p  端口
    -a  密码
    
    redis-cli -h 10.31.1.124 -p 6379 -a "123456"

测试记录:

[root@10-31-1-123 ~]# redis-cli -h 10.31.1.124 -p 6379 -a "123456"
    10.31.1.124:6379>
