通过redmon监控管理Redis服务器的安装配置教程

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

准备工作:

sudo apt-get updatesudo apt-get upgradesudo apt-get dist-upgradesudo 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)

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

; 查看安装建议rvm notes; 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-p0rvm 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 -vgem -v; 有必要可以手动更新一下gem update --systemgem update; 安装railsgem 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 undefinedsrc/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 installruby 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。
