redis5.0.3安裝
參考redis 中文網 http://www.redis.cn/
下載、解壓、編譯Redis
$ wget http://download.redis.io/releases/redis-5.0.3.tar.gz
$ tar xzf redis-5.0.3.tar.gz
$ cd redis-5.0.3
$ make
簡單啓動
進入到解壓後的 src 目錄，通過如下命令啓動Redis:
$ src/redis-server
簡單交互
您可以使用內置的客戶端與Redis進行交互:
$ src/redis-cli
redis> set foo bar
OK
redis> get foo
"bar"
正常安裝
以下兩個選項任選其一進行 (推薦選擇默認安裝)
- 安裝命令 (默認安裝目錄是/usr/local/bin/)
[root@localhost redis-5.0.3]# make install #安裝
[root@localhost redis-5.0.3]# ll /usr/local/bin/redis* #查看目錄
-rwxr-xr-x. 1 root root 4367312 1月 25 02:54 /usr/local/bin/redis-benchmark
-rwxr-xr-x. 1 root root 8092014 1月 25 02:54 /usr/local/bin/redis-check-aof
-rwxr-xr-x. 1 root root 8092014 1月 25 02:54 /usr/local/bin/redis-check-rdb
-rwxr-xr-x. 1 root root 4802679 1月 25 02:54 /usr/local/bin/redis-cli
lrwxrwxrwx. 1 root root 12 1月 25 02:54 /usr/local/bin/redis-sentinel -> redis-server
-rwxr-xr-x. 1 root root 8092014 1月 25 02:54 /usr/local/bin/redis-server
- 指定redis安裝目錄
[root@localhost redis-5.0.3]# make install PREFIX=/usr/local/redis #安裝
配置文件
配置文件在redis-5.0.3目錄下,文件名是 redis.conf
根據你的安裝目錄,將配置文件拷貝至對應的目錄,比如拷貝到 /etc/目錄下,命令如下:
[root@localhost redis-5.0.3]# cp redis.conf /etc/
正常啓動
啓動redis命令和效果如下,默認是前臺啓動,按 ctrl+c 停止
[root@localhost ~]# redis-server /etc/redis.conf

後臺啓動
後臺啓動需要修改配置文件 (大概在136行 ),將daemonize no 改爲 daemonize yes
```
135 # Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
136 daemonize no
137
138 # If you run Redis from upstart or systemd, Redis can interact with your
```
重啓啓動,效果如下
[root@localhost ~]# redis-server /etc/redis.conf

遠程客戶端連接
直接使用客戶端加參數 redis-cli -h <ip> 進行遠程連接
[root@localhost ~]# redis-cli -h 192.168.25.254

默認配置會報錯,連接被拒絕,需要修改配置文件 redis.conf
默認配置,69行默認綁定了本機地址,註釋此配置
