1.redis-stat介绍

一个用ruby写成的监控redis的程序，基于info命令获取信息，不会像基于MONITOR命令的监控工具一样，对Redis本身有性能上的影响。

github项目地址：https://github.com/junegunn/redis-stat

必要的linux库安装

yum -y install zlib-devel  openssl-devel  cmake build-essential autoconf automake libtool zlib1g-dev pkg-config libssl-dev

2.redis-stat在线安装(官网推荐方式，服务器需要可以连接外网)

2.1 在官网下载redis-stat,下载截图如下：

下载后得到redis-stat-master.zip,下载完后解压如下：

cd /opt
wget https://github.com/junegunn/redis-stat/archive/redis-stat-master.zip
unzip redis-stat-master.zip -d redis-stat-0.4.14

2.2 redis-stat安装(机器必须联网，不然无法正常安装)

(1)必要的linux库安装

yum -y install zlib-devel  openssl-devel  cmake build-essential autoconf automake libtool zlib1g-dev pkg-config libssl-dev

(2)ruby安装

cd /opt
wget https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.1.tar.gz
tar -zxvf ruby-2.3.1.tar.gz
cd /opt/ruby-2.3.1
./configure
make
make install

#检测ruby环境

#检测rubygems
3RubyGems（简称 gems）是一个用于对 Ruby组件进行打包的 Ruby 打包系统。 
#它提供一个分发 Ruby 程序和库的标准格式，还提供一个管理程序包安装的工具。 
#Ruby1.9.2之后版本版本默认自带RubyGems，如果低于这个版本的话，需要自行安装RubyGems， 
#参照这里安装http://storysky.blog.51cto.com/628458/1155353/ 
#因为我是ruby2.3.1所以不需要安装此组件，已经自带了 
#检查RubyGems是否安装好的方法如下： 
gem -v
2.5.1

(3)ruby的扩展库zlib安装

cd /opt/ruby-2.3.1/ext/zlib
ruby ./extconf.rb
make
make install

(4)ruby的扩展库openssl安装

cd /opt/ruby-2.3.1/ext/openssl
ruby ./extconf.rb
#如果遇到报错make: *** No rule to make target `/include/ruby.h', needed by `ossl_ssl_session.o'.  Stop.
#在文件/opt/ruby-2.3.1/ext/openssl/Makefile里添加如下变量top_srcdir，值为ruby源代码的根路径/opt/ruby-2.3.1
#top_srcdir=/opt/ruby-2.3.1
make
make install

(5)redis-stat在线安装 这种方式必须能联网，默认会从https://rubygems.org/下载ruby相关库

gem install redis-stat

3.redis-stat离线安装

3.1 在官网下载redis-stat,下载截图如下：

cd /opt
wget https://github.com/junegunn/redis-stat/archive/redis-stat-master.zip
unzip redis-stat-master.zip -d redis-stat-0.4.14

3.2 离线安装redis-stat

redis-stat的核心是需要在安装了ruby、rubygems以及redis后，只要成功安装redis-stat-0.4.14.gem就可以了，而安装redis-stat-0.4.14.gem的前提是需要安装redis-stat-0.4.14.gem相关的依赖，这些依赖都可以在https://rubygems.org/一一找到，https://rubygems.org/网站截图如下：

(1)必要的linux库安装

yum -y install zlib-devel  openssl-devel  cmake build-essential autoconf automake libtool zlib1g-dev pkg-config libssl-dev

(2)ruby安装

cd /opt
wget https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.1.tar.gz
tar -zxvf ruby-2.3.1.tar.gz
cd /opt/ruby-2.3.1
./configure
make
make install

#检测ruby环境
ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]

(3)ruby的扩展库zlib安装

cd /opt/ruby-2.3.1/ext/zlib
ruby ./extconf.rb
make
make install

(4)ruby的扩展库openssl安装

cd /opt/ruby-2.3.1/ext/openssl
ruby ./extconf.rb
#如果遇到报错make: *** No rule to make target `/include/ruby.h', needed by `ossl_ssl_session.o'.  Stop.
#在文件/opt/ruby-2.3.1/ext/openssl/Makefile里添加如下变量top_srcdir，值为ruby源代码的根路径/opt/ruby-2.3.1
#top_srcdir=/opt/ruby-2.3.1
make
make install

(5)redis-stat离线安装

在https://rubygems.org/下载redis-stat-0.4.14.gem以及其相关依赖的gem文件，这里我下载的相关gem如下：

ansi256-0.2.5.gem
daemons-1.1.9.gem
elasticsearch-1.0.0.gem
elasticsearch-api-1.0.0.gem
elasticsearch-transport-1.0.0.gem
eventmachine-1.2.0.1.gem
faraday-0.9.2.gem
insensitive_hash-0.3.0.gem
lps-0.2.0.gem
multipart-post-1.2.0.gem
multi_json-1.12.1.gem
openssl-0.2.0.gem
option_initializer-1.5.0.gem
parallelize-0.4.0.gem
rack-1.3.6.gem
rack-protection-1.2.0.gem
rb-readline-0.5.3.gem
redis-3.0.7.gem
redis-3.2.1.gem
redis-stat-0.4.14.gem
si-0.1.4.gem
sinatra-1.3.3.gem
tabularize-0.2.9.gem
thin-1.5.0.gem
tilt-1.3.3.gem
unicode-display_width-0.1.1.gem

下载完后，依次安装顺序如下：

gem install --local daemons-1.1.9.gem
gem install --local rack-1.3.6.gem
gem install --local eventmachine-1.2.0.1.gem
gem install --local thin-1.5.0.gem

gem install --local multi_json-1.12.1.gem
gem install --local faraday-0.9.2.gem
gem install --local elasticsearch-api-1.0.0.gem
gem install --local elasticsearch-transport-1.0.0.gem
gem install --local elasticsearch-1.0.0.gem

gem install --local multipart-post-1.2.0.gem
gem install --local option_initializer-1.5.0.gem
gem install --local lps-0.2.0.gem

gem install --local tilt-1.3.3.gem
gem install --local rack-protection-1.2.0.gem
gem install --local sinatra-1.3.3.gem

gem install --local si-0.1.4.gem

gem install --local parallelize-0.4.0.gem

gem install --local insensitive_hash-0.3.0.gem

gem install --local unicode-display_width-0.1.1.gem
gem install --local tabularize-0.2.9.gem

gem install --local redis-3.0.7.gem

gem install --local ansi256-0.2.5.gem

gem install --local rb-readline-0.5.3.gem

gem install --local redis-stat-0.4.14.gem

安装完成后基本就可以去检测redis-stat是否可用了，检测方法是：

cd /opt
wget https://github.com/junegunn/redis-stat/archive/redis-stat-master.zip
unzip redis-stat-master.zip -d redis-stat-0.4.14
cd /opt/redis-stat-0.4.14/bin
./redis-stat -help
#正确显示帮助信息就代表安装成功

遇到错误的话别紧张，一般还是缺少相关gem，只需要在https://rubygems.org下载相应gem本地化安装就行，例如如下错误信息：

/usr/local/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- readline (LoadError)
from /usr/local/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from /usr/local/lib/ruby/gems/2.3.0/gems/redis-stat-0.4.14/lib/redis-stat.rb:17:in `<top (required)>'
from /usr/local/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:127:in `require'
from /usr/local/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:127:in `rescue in require'
from /usr/local/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:40:in `require'
from ./redis-stat:4:in `<main>'

解决办法是，去https://rubygems.org下载rb-readline-0.5.3.gem,然后通过gem install --local rb-readline-0.5.3.gem进行安装就能解决，一切安装就绪后，redis-stat能用的正确提示如下：

cd /opt/redis-stat-0.4.14/bin
./redis-stat -help

usage: redis-stat [HOST[:PORT] ...] [INTERVAL [COUNT]]

-a, --auth=PASSWORD Password
-v, --verbose Show more info

4.redis-stat使用

参见官网：https://github.com/junegunn/redis-stat

参见：http://www.ohcoder.com/blog/2015/02/15/redis-stat/

后台启动方式如下：

cd /opt/redis-stat-0.4.14/bin
./redis-stat 192.168.173.23:6379 192.168.173.23:6380 192.168.173.23:6381 192.168.173.24:6379 192.168.173.24:6380 192.168.173.24:6381 --server --daemon
