转载:http://blog.csdn.net/qq_19260029/article/details/77920423
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

Redis must be restarted after THP is disabled.

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。

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!

RedisDesktopManager连接远程Linux系统的Redis服务(<a href=图文)" src="http://img.blog.csdn.net/20170910104503324?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvcXFfMTkyNjAwMjk=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast" alt="链接失败" title="">

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。
当你信心满满的时候,现实总泼你一盆冷水来清醒!链接失败,链接失败,我都不好意思截图上传了!!这又是闹哪样啊?还让我活不???

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         
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

8    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:15672

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         
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    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:6379 
10   REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited

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
