1. 安裝時可能遇到的問題

    問題1：make[3]: gcc: Command not found  
    解決： Centos系統執行yum install gcc；
          Ubuntu系統執行apt-get install gcc；

    問題2：zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory 
          zmalloc.h:55:2: error: #error “Newer version of jemalloc required” 
          make[1]: * [adlist.o] Error 1 
    解決：輸入make MALLOC=libc，然後重新編譯
 

2. 安裝完成之後進入redis安裝目錄執行

    [[email protected] src]# ./redis-server

3. Redis服務已經可以成功啟動了，介面一直停留在Redis服務視窗中，按Ctrl+C雖然可以遮蔽服務視窗，但同時也會結束Redis服務

4. Redis服務預設是前臺執行，需要修改為後臺執行；返回上一層目錄，修改redis.conf配置檔案。找到daemonize（守護程序）配置，預設no。

    修改前 daemonize no

    修改後 daemonize yes

5. 啟動服務的同時讀取最新的配置檔案

    [[email protected] src]# ./redis-server ../redis.conf

6. 使用RedisDesktopManager客戶端，輸入伺服器IP地址，埠，點選測試:

成功？over!———————-失敗，繼續往下看

7. Redis預設只支援本地連結，修改預設配置

    [[email protected] src]# ps -ef | grep redis 
    root 5239 1 0 10:37 ? 00:00:00 ./redis-server 127.0.0.1:6379 
    root 5244 2321 0 10:37 pts/0 00:00:00 grep redis

    問題解決：編輯redis.conf配置檔案；註釋掉61行本地連結限制以及80行配置修改為no
    56 # bind 127.0.0.1 
    70 protected-mode no

    讀取最新配置檔案並重啟，檢視Redis程序情況，還是127.0.0.1:6379

    [[email protected] src]# ./redis-server ../redis.conf 
    [[email protected] src]# ps -ef | grep redis 
    root 5352 1 0 10:59 ? 00:00:00 ./redis-server 127.0.0.1:6379 
    root 5367 2321 0 11:00 pts/0 00:00:00 grep redis

    殺掉Redis程序，再讀取最新配置檔案並重啟

    [[email protected] src]# redis-cli shutdown 
    [[email protected] src]# ./redis-server ../redis.conf

    再檢視程序情況：

    [[email protected] src]# ps -ef | grep redis 
    root 5391 1 0 11:05 ? 00:00:00 ./redis-server *:6379 
    root 5395 2321 0 11:05 pts/0 00:00:00 grep redis

8. 防火牆設定

    [[email protected] src]# service iptables status
    表格：filter
    Chain INPUT (policy ACCEPT)
    num  target     prot opt source               destination         
    1    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           state RELATED,ESTABLISHED 
    2    ACCEPT     icmp --  0.0.0.0/0            0.0.0.0/0           
    3    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           
    4    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:22 
    5    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:8080 
    6    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:80 
    7    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:3306 
    8    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:15672  
    9   REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited

    編輯Linux防火牆 
    [[email protected] src]# vi /etc/sysconfig/iptables 
    加入防火牆規則：-A INPUT -m state –state NEW -m tcp -p tcp –dport 6379 -j ACCEPT

    重啟Linux防火牆 
    [[email protected] src]# service iptables restart

    點選Test Connection按鈕測試連線，連線成功！！！
