redis ruby 监控 redmon 安装

1. 通过RVM(Ruby Version Manager)来安装配置Ruby On Rails

准备工作：

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo reboot

安装RVM：

bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

安装完成后会提示：

andy@ubuntu:~$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
Downloading RVM from wayneeseguin branch stable

Installing RVM to /home/andy/.rvm/
Adding rvm PATH line to /home/andy/.bashrc /home/andy/.zshrc.
Adding rvm loading line to /home/andy/.bash_login /home/andy/.zlogin.

# RVM: Shell scripts enabling management of multiple ruby environments.
# RTFM: https://rvm.beginrescueend.com/
# HELP: http://webchat.freenode.net/?channels=rvm (#rvm on irc.freenode.net)
# Screencast: http://screencasts.org/episodes/how-to-use-rvm

# In case of any issues read output of 'rvm requirements' and/or 'rvm notes'

Installation of RVM in /home/andy/.rvm/ is almost complete:

* To start using RVM you need to run `source /home/andy/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.

* Optionally you can run `rvm tools rvm-env ruby bash` which will generate
shebang wrappers for easier selecting ruby in scripts.

# andy,
#
# Thank you for using RVM!
# I sincerely hope that RVM helps to make your life easier and more enjoyable!!!
#
# ~Wayne

andy@ubuntu:~$ source /home/andy/.rvm/scripts/rvm
andy@ubuntu:~$ rvm tools rvm-env ruby bash

# use shebang: #!/usr/bin/ruby-rvm-env 1.9.3
There is no command/script 'ruby' in system.
Created link '/usr/bin/bash-rvm-env'.

通过下面的命令可以查看RVM是否正常工作：

andy@ubuntu:~$ source .bashrc
andy@ubuntu:~$ type rvm | head -1
rvm is a function

如果正常的话可以看到类似“rvm是函数”这样的内容，下面我们安装ruby以及rail

andy@ubuntu:~/baidu/lxb/apps/redmon$ bundle install

andy@ubuntu:~/baidu/lxb/apps/redmon$ gem install bundler

; 安装一些必要的软件包
sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev
; 列出可以安装的ruby版本
rvm list known
; 安装ruby，我选择的是版本1.9.3-p0
rvm install 1.9.3-p0
; 设定默认使用的ruby版本
rvm --default use 1.9.3-p0
; 查看版本看是否正确安装
ruby -v
gem -v
; 有必要可以手动更新一下
gem update --system
gem update
; 安装rails
gem install rails
; 查看版本看是否正确安装
rails -v

这样环境就安装好了，下面提一下安装过程中可能遇到的错误信息：

在安装ruby的时候会安装yaml，可能会在make的时候出现如下的错误信息：

Compiling yaml in /home/debugcool/.rvm/src/yaml-0.1.4.
ERROR: Error running 'make ', please read /home/debugcool/.rvm/log/ruby-1.9.3-p0/yaml/make.log

这是应为缺少yaml库的缘故，可以通过：

sudo apt-get install libyaml-0-2 libyaml-dev

执行这个命令来安装yaml库解决这个问题，如果还是报错，请看b错误信息

查看 /home/debugcool/.rvm/log/ruby-1.9.3-p0/yaml/make.log 日志信息：

src/Makefile.am:2: Libtool library used but `LIBTOOL' is undefined
src/Makefile.am:2:   The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'

缺少libtool库，可以通过：

sudo apt-get install libtool

执行这个命令来安装libtool库解决这个问题

2. 安装redmon监控redis

下载redmon源码：

git clone https://github.com/steelThread/redmon.git

安装运行：

bundle install
ruby sample/app.rb

注：如果前面不是通过RVM进行ruby、rails安装配置，而是通过源码编译、apt-get等方式安装，可能会遇到各种找不到相关gem等诡异的错误，我也是在各种百度、google无果之后才通过RVM来安装的。

运行之后可以打开在浏览器中打开http://localhost:4567来查看redis web监控页面。

redmon默认是监控本机的6379端口的redis服务器，这个是可以修改的，在redmon目录的lib目录下，可以查看redmon.rb的源码：

module Redmon
  extend self

  attr_reader :opts

  @opts = {
    :redis_url     => 'redis://127.0.0.1:6379',
    :namespace     => 'redmon',
    :web_interface => ['0.0.0.0', 4567],
    :worker        => true,
    :poll_interval => 10
  }

修改上面代码中redis_url内容即可监控自己执行的redis服务器。
