介绍安装以及简单的配置。

Redis 安装

下载安装，进官网：https://redis.io/

建议将解压目录放到 /opt 下：

[root@AndyCentOS7Basic ~]# wget http://download.redis.io/releases/redis-5.0.5.tar.gz
[root@AndyCentOS7Basic ~]# tar xzf redis-5.0.5.tar.gz
[root@AndyCentOS7Basic ~]# mv redis-5.0.5 /opt/

参照官网，安装步骤：

1 2	[root@AndyCentOS7Basic ~]# cd /opt/redis-5.0.5/ [root@AndyCentOS7Basic ~]# make

make test

[root@localhost redis-5.0.7]# make test
cd src && make test
make[1]: Entering directory `/root/redis-5.0.7/src'
    CC Makefile.dep
make[1]: Leaving directory `/root/redis-5.0.7/src'
make[1]: Entering directory `/root/redis-5.0.7/src'
You need tcl 8.5 or newer in order to run the Redis test
make[1]: *** [test] Error 1
make[1]: Leaving directory `/root/redis-5.0.7/src'
make: *** [test] Error 2

解决：

1	yum install -y tcl

以后台程序方式运行:

1	[root@AndyCentOS7Basic ~]# /opt/redis-5.0.5/src/redis-server &

检查后台进程是否正在运行

没有运行：

1 2	[root@AndyCentOS7Basic ~]# ps -ef \|grep redis root 1726 1707 0 09:01 pts/1 00:00:00 grep --color=auto redis

运行后：

[root@AndyCentOS7Basic ~]# ps -ef |grep redis
root      6105  1998  0 08:26 pts/2    00:00:00 /opt/redis-5.0.5/src/redis-server *:6379
root      6127  6109  0 08:27 pts/3    00:00:00 grep --color=auto redis

检测6379端口是否在监听

[root@AndyCentOS7Basic ~]# netstat -lntp | grep 6379
tcp        0      0 0.0.0.0:6379            0.0.0.0:*               LISTEN      6130/redis-server *

退出redis服务器

[root@AndyCentOS7Basic ~]# /opt/redis-5.0.5/src/redis-cli shutdown
6130:M 30 May 2019 09:14:18.481 # User requested shutdown...

6130:M 30 May 2019 09:14:18.548 # Redis is now ready to exit, bye bye...
[1]+  Done                    /opt/redis-5.0.5/src/redis-server

因为Redis可以妥善处理SIGTERM信号，所以直接 kill -9 PID 也是可以的。

[root@AndyCentOS7Basic ~]# ps -ef |grep redis
root      6199  1998  0 09:20 pts/2    00:00:00 /opt/redis-5.0.5/src/redis-server *:6379
root      6205  1998  0 09:22 pts/2    00:00:00 grep --color=auto redis
[root@AndyCentOS7Basic ~]# kill -9 6199
[root@AndyCentOS7Basic ~]# ps -ef |grep redis
root      6207  1998  0 09:22 pts/2    00:00:00 grep --color=auto redis
[1]+  Killed                  /opt/redis-5.0.5/src/redis-server

redis 设置密码登录后，要用 redis-cli 关闭 redis 服务器，需要 redis-cli -a 密码 shutdown

修改配置项

1	vim /opt/redis-5.0.5/redis.conf

设置访问需要密码：# requirepass foobared 改为：requirepass andyRedisPass，其中 andyRedisPass 为密码，改为你自己的密码。
bind 127.0.0.1 直接注释掉，改为：# bind 127.0.0.1
将 daemonize no 改为 daemonize yes，作用是默认启动时为后台启动。

protected-mode 属性

redis3.2 版本后新增 protected-mode 配置，默认是 protected-mode yes，即开启。
设置外部网络连接 redis 服务时，与该配置相关，如下：

关闭 protected-mode 模式，即改为：protected-mode no，此时外部网络可以直接访问（连接）。
开启 protected-mode 保护模式，需配置 bind ip 或者设置访问密码才能访问（连接）。

指定配置文件启动

[root@AndyCentOS7Basic ~]# /opt/redis-5.0.5/src/redis-server /opt/redis-5.0.5/redis.conf &
[1] 6209
[root@AndyCentOS7Basic ~]# 6209:C 30 May 2019 09:25:05.539 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
