RedisDesktopManager连接远程Linux系统的Redis服务（图文）

Linux环境：Centos 6.8
Redis服务端版本：3.2.6
Redis客户端下载链接：https://redisdesktop.com/download

省略Linux系统安装Redis教程，网上安装教程很多；建议用tar.gz包安装
Redis官网tar.gz下载地址：wget http://download.redis.io/releases/redis-3.2.6.tar.gz

安装时可能遇到的问题

问题1：make[3]: gcc: Command not found
解决：Centos系统执行yum install gcc；Ubuntu系统执行apt-get install gcc

问题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
解决：输入make MALLOC=libc，然后重新编译

安装完之后，进入Redis安装目录

此时Redis服务已经可以成功启动了；但问题来了，界面一直停留在Redis服务窗口中，按Ctrl+C虽然可以屏蔽服务窗口，但同时也会结束Redis服务。

2745:M 10 Sep 10:23:04.765 # User requested shutdown…

2745:M 10 Sep 10:23:04.765 * Saving the final RDB snapshot before exiting.

2745:M 10 Sep 10:23:04.767 * DB saved on disk
2745:M 10 Sep 10:23:04.767 # Redis is now ready to exit, bye bye…

Redis服务默认是前台运行，需要修改为后台运行；返回上一层目录，修改redis.conf配置文件。找到daemonize（守护进程）配置，默认false。
修改后：

daemonize yes

此时满脸自信地回到src目录执行

[root@Karle src]# ./redis-server

擦，还是前台运行；咋回事？什么毛病？这是咱们修改了配置文件，但没告诉Redis读取最新的配置文件。启动服务的同时读取最新的配置文件

[root@Karle src]# ./redis-server ../redis.conf

下载RedisDesktopManager客户端，输入服务器IP地址，端口（缺省值：6379）；点击Test Connection按钮测试连接，噢，My God，连接失败！

什么问题呢？原因是Redis默认只支持本地链接，输入进程命令查看得知（127.0.0.1:6379）

[root@Karle 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

问题解决：编辑redis.conf配置文件；注释掉61行本地链接限制以及80行配置修改为no

61 # bind 127.0.0.1
80 protected-mode no

读取最新配置文件并重启，查看Redis进程情况！我再擦，什么鬼，都开放IP链接权限了，怎么还是127.0.0.1:6379！！

[root@Karle src]# ./redis-server ../redis.conf
[root@Karle 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

问题解决：先杀掉Redis进程，src目录下依次执行

[root@Karle src]# redis-cli shutdown
[root@Karle src]# ./redis-server ../redis.conf

再查看进程情况：

[root@Karle 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

哇塞，.6379，这意味着已经成功开放IP访问权限了。万事俱备，只欠点击RedisDesktopManager客户端测试链接按钮了。好，走起。
当你充满自信的时候，现实总是给你泼冷水，让你醒过来！链接失败，链接失败，不好意思上传截图！这里发生了什么事？你会不会让我活下去？

左思右想，突然，我想到一个词——防火墙

[root@Karle src]# service iptables status
表格：filter
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination
<span class="hljs-number">1    ACCEPT     <span class="hljs-keyword">all  </span></span>

编辑Linux防火墙
[root@Karle src]# vi /etc/sysconfig/iptables
加入防火墙规则：-A INPUT -m state –state NEW -m tcp -p tcp –dport 6379 -j ACCEPT

[root@Karle src]# service iptables status
表格：filter
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination
<span class="hljs-number">1    ACCEPT     <span class="hljs-keyword">all  </span></span>

重启Linux防火墙
[root@Karle src]# service iptables restart

点击Test Connection按钮测试连接，连接成功，大功告成
