redis4.0 安裝

本地環境：Centos 7.6

 

https://redis.io/download

在官網找了半天只有5.0  6.0的下載地址，沒有找到4.0的下載址，

http://www.redis.cn/download.html

在redis中文網上才找到下載地址。

 

wget http://download.redis.io/releases/redis-4.0.11.tar.gz

tar xvf redis-4.0.11.tar.gz -C /usr/local/

cd /usr/local/redis-4.0.11/

make

 

 

提示這些表示安裝完成：

Hint: It's a good idea to run 'make test' ;)

make[1]: Leaving directory `/usr/local/redis-4.0.11/src'

[root@iZ8vbdjpjvhsbz4w10d7rhZ redis-4.0.11]# src/redis-server    #啟動數據庫

 

新開一個窗口，連接寫入查詢數據庫

[root@iZ8vbdjpjvhsbz4w10d7rhZ redis-4.0.11]# /usr/local/redis-4.0.11/src/redis-cli 
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> set a 1
OK
127.0.0.1:6379> get a
"1"
127.0.0.1:6379>

 

將  /usr/local/redis-4.0.11/src/ 目錄添加到PATH環境變量中

vi ~/.bash_profile 

PATH=$PATH:/usr/local/redis-4.0.11/src/

source  ~/.bash_profile 

 

看下redis-server 命令行參數

[root@iZ8vbdjpjvhsbz4w10d7rhZ redis-4.0.11]# src/redis-server --help
Usage: ./redis-server [/path/to/redis.conf] [options]
       ./redis-server - (read config from stdin)
       ./redis-server -v or --version
       ./redis-server -h or --help
       ./redis-server --test-memory <megabytes>

Examples:
       ./redis-server (run the server with default conf)  #不加參數會加載默認的conf配置文件
       ./redis-server /etc/redis/6379.conf　　　　　　　　　　#指定某個conf配置文件
       ./redis-server --port 7777　　　　　　　　　　　　　　　　#指定端口號，這個參數在conf配置文件中也有
       ./redis-server --port 7777 --slaveof 127.0.0.1 8888　　#指定端口號和主庫的IP地址、端口號
       ./redis-server /etc/myredis.conf --loglevel verbose　　 #指定配置文件，同時指定loglevel參數值為 verbose

Sentinel mode: ./redis-server /etc/sentinel.conf --sentinel　　 #以哨兵的模式啟動，后續會寫

可以看到，參數可以顯式的在運行redis-server時指定，如果顯式指定的參數與配置文件中的參數值不同，則以顯式指定的參數值為准。

 

編輯配置文件，修改如下幾個參數

 

vi /usr/local/redis-4.0.11/redis.conf



bind 0.0.0.0　　　　#允許所有IP連接redis數據庫

appendonly yes　　　　#開啟aof日志

dir /usr/local/redis-4.0.11　　#指定rdb生成的文件目錄，這個參數默認值是./ 意味着rdb文件會生成在redis-server運行時的目錄下。

保存退出，再次啟動，可以看到啟動執行
