Redis监控之redis-stat
监控的界面比较简单，也没有邮件报警之类的功能。
命令行界面：
web界面（记得关闭防火墙）：
安装的方式有3种
1.java -jar启动jar包
2.安装ruby后使用gem install redis-stat在线联网安装
3.安装ruby后，gem离线安装
其中，第1种最简单，这里先介绍第1种方式。
java -jar启动jar包
下载链接：https://github.com/junegunn/redis-stat/releases
安装java环境：rpm -ivh jdk-8u301-linux-x64.rpm
启动：java -jar redis-stat-0.4.14.jar 192.168.1.214:6380 192.168.1.214:6379 192.168.1.214:6381 --server=8090 --verbose
这样就完成了。
web访问使用192.168.1.179:8090即可。
也可以使用nohup java -jar redis-stat-0.4.14.jar 192.168.1.214:6380 192.168.1.214:6379 192.168.1.214:6381 --server=8090 --verbose &放后台执行，但是要立刻exit推出SecureCRT会话。不然会报如下错误：
[root@node3 redis-stat]# nohup java -jar redis-stat-0.4.14.jar 192.168.1.214:6380 192.168.1.214:6379 192.168.1.214:6381 --server=8090 --verbose & [1] 12387 [root@node3 redis-stat]# nohup: ignoring input and appending output to ‘nohup.out’ [root@node3 redis-stat]# [1]+ Stopped nohup java -jar redis-stat-0.4.14.jar 192.168.1.214:6380 192.168.1.214:6379 192.168.1.214:6381 --server=8090 --verbose [root@node3 redis-stat]# jobs [1]+ Stopped nohup java -jar redis-stat-0.4.14.jar 192.168.1.214:6380 192.168.1.214:6379 192.168.1.214:6381 --server=8090 --verbose
搞不懂。
另外两种方式均需要安装ruby功能。
参考我的另外一篇博客：ruby安装指南
安装ruby后使用gem install redis-stat在线联网安装
使用gem install redis-stat安装即可。
如果是通过yum安装的ruby，在CentOS Linux 7下，有ruby版本过低的问题。
[root@node1 ~]# ruby -v ruby 2.0.0p648 (2015-12-16) [x86_64-linux] [root@node1 ~]# gem install redis-stat ERROR: Error installing redis-stat: faraday-em_http requires Ruby version >= 2.4.0.
估计是redis-stat版本过高，但是安装指定的redis-stat又报错另外的。
[root@node1 ~]# gem install redis-stat --version 0.3.9 Building native extensions. This could take a while... ERROR: Error installing redis-stat: ERROR: Failed to build gem native extension. /usr/bin/ruby extconf.rb mkmf.rb can't find header files for ruby at /usr/share/include/ruby.h Gem files will remain installed in /usr/local/share/gems/gems/eventmachine-1.2.7 for inspection. Results logged to /usr/local/share/gems/gems/eventmachine-1.2.7/ext/gem_make.out
通过编译安装的ruby，版本比较高则不会有问题。

就是使用redis-stat报错。。。

目前尚未找到解决方法。
感觉是ruby版本过高导致的，有时间试试2.4.0版本的ruby。
安装ruby后，gem离线安装
待补充。
