默认开启的 redis 是一个前台的进程，窗口必须一直开着，一旦关闭，redis 服务端就会关闭，设置redis 以后台进程的方式启动

1.备份redis.conf
先Ctrl+c停掉

cp redis.conf redis.conf.backup

[root@lrz redis]# cp redis.conf redis.conf.backup
[root@lrz redis]# ll
total 340
......
-rw-rw-r--  1 root root  61797 Nov 20 01:05 redis.conf
-rw-r--r--  1 root root  61797 Jan  8 11:57 redis.conf.backup
......

2.修改redis.conf配置

vim redis.conf

搜索

:/daemonize

......
################################# GENERAL #####################################

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize no

......

把daemonize no改为daemonize yes
保存退出

3.重新启动
让 redis 运行时加载我们指定的配置文件，而不是它默认的：

./src/redis-server redis.conf

[root@lrz redis]# ./src/redis-server redis.conf
23735:C 08 Jan 2020 13:14:23.192 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
23735:C 08 Jan 2020 13:14:23.192 # Redis version=5.0.7, bits=64, commit=00000000, modified=0, pid=23735, just started
23735:C 08 Jan 2020 13:14:23.192 # Configuration loaded

查看

ps -ef|grep redis

[root@lrz redis]# ps -ef|grep redis
root     23736     1  0 13:14 ?        00:00:01 ./src/redis-server 127.0.0.1:6379
root     26100 22684  0 13:32 pts/1    00:00:00 ./src/redis-cli
root     26210  3993  0 13:33 pts/0    00:00:00 grep --color=auto redis

客户端

启动 redis 客户端

./src/redis-cli

[root@lrz redis]# ./src/redis-cli
127.0.0.1:6379>

校验是否连通

127.0.0.1:6379> ping
PONG

说明成功

查看版本

./src/redis-server -v

或

./src/redis-cli -v

严格上说：通过　redis-cli 得到的结果应该是redis-cli 的版本，但是 redis-cli 和redis-server　一般都是从同一套源码编译出的。所以应该是一样的。

或

./src/redis-cli info | grep 'redis_version'

[root@lrz redis]# ./src/redis-cli info | grep 'redis_version'
redis_version:5.0.7

关闭redis

./src/redis-cli shutdown

或

./src/redis-cli -p 6379 shutdown

[root@lrz redis]# ps -ef|grep redis
root     29832  3993  0 14:01 pts/0    00:00:00 grep --color=auto redis
