在 CentOS 5.8 上安装 Graphite

标签(空格分隔): 监控 monitor CentOS 5.8 Graphite


首先说一句,在 CentOS 5.8 上安装真的很坑爹。。。

基础环境

  • 操作系统内核
uname -a

Linux cloud-test-slave-001 2.6.18-308.el5 #1 SMP Tue Feb 21 20:06:06 EST 2012 x86_64 x86_64 x86_64 GNU/Linux
  • 操作系统版本
[[email protected] ~]# cat /etc/redhat-release 
CentOS release 5.8 (Final)
  • Python 版本
[[email protected] ~]# python  --version
Python 2.7

必备软件

按照 Graphite 官方文档的要求,需要如下软件:

python2.4 或者更高版本(必选)【建议 2.6 或 2.7 版本】
pycairo (需要 PNG 包支持,即 libpng)(必选)
mod_python(必选)
django(必选,需要 django 1.4 版本,为什么必须 django 1.4 在后面会说明)
python-ldap (可选 - needed for ldap-based webapp authentication)
python-memcached (可选 - needed for webapp caching, big performance boost)
python-sqlite2 (可选 - a django-supported database module is required)
bitmap and bitmap-fonts required on some systems, 尤其是在 Red Hat 系统上

下面是我目前安装的一些涉及到的软件的版本(可能有多余的,是因为我在虚拟环境安装,没有安装好,只好混装,所以拉出来的有点多)

执行命令 pip freeze 拉出如下清单:

Django==1.4
Dozer==0.4
Jinja2==2.7.3
MarkupSafe==0.23
PyYAML==3.10
SQLAlchemy==0.9.7
Twisted==14.0.2
WebOb==1.4
Werkzeug==0.9.6
alembic==0.6.5
configobj==5.0.6
croniter==0.3.3
cssselect==0.9.1
daemonize==2.3.1
dagobah==0.2.3
distribute==0.6.49
django-filter==0.7
django-tagging==0.3.1
lxml==3.3.5
micawber==0.3.0
paramiko==1.11.0
peewee==2.2.5
premailer==1.13
pycrypto==2.6.1
pysqlite==2.6.3
python-dateutil==2.2
python-memcached==1.53
txAMQP==0.6.2
uWSGI==2.0.7
virtualenv==1.11.6
whisper==0.9.12
wsgiref==0.1.2
zope.interface==4.1.1

开始安装

  1. 安装 yum EPEL 源

    wget "http://mirrors.ustc.edu.cn/fedora/epel/5/i386/epel-release-5-4.noarch.rpm"
    rpm -Uvh epel-release-5-4.noarch.rpm
    
  2. 安装依赖包

    yum install gcc bitmap bitmap-fonts zope
    
    yum install openldap openldap24-libs openldap-clients openldap-devel openssl-devel
    
    pip install pyOpenSSL python-memcached pycrypto  python-ldap  pysqlite uwsgi nginx
    

    注:因为我这个目前是测试,所以 nginx 就直接 yum 安装了,版本比较低,只有 0.8,如果是生产,建议源码安装最新的稳定版本。

    pip install django==1.4
    

    安装 django-tagging ,默认的 pip install tagging 的这个不行,版本是 0.2.1 ,会报错。

    pip install django-tagging==0.3.1 或 pip install tagging==0.3.1
    

    如果上面这个方法无法安装 django-tagging=0.3.1 那就用源码安装的方法。

    wget https://pypi.python.org/packages/source/d/django-tagging/django-tagging-0.3.1.tar.gz --no-check-certificate
    tar -zxvf django-tagging-0.3.1.tar.gz 
    cd django-tagging-0.3.1
    python setup.py install
    
  3. 安装 pycairo

    开始好几次就死在安装 pycairo 这个上面,python 2.7 版本的通过 pip install pycairo 命令安装的不行,对应 python 2.7 版本的 pycairo 包的名字叫做 py2cairo

    安装 py2cairo 包的方法如下:

    1)下载 py2cairo 包:

    wget http://www.cairographics.org/releases/py2cairo-1.10.0.tar.bz2
    tar -xvf py2cairo-1.10.0.tar.bz2
    

    如果上面的版本不行就用下面的方式获取源码包:

     git clone git://git.cairographics.org/git/py2cairo
    

    要安装 py2cairo 必须要 cairo 包,而且这个包的版本有规定,我这边下载的是 cairo-1.12.2。

    wget http://cairographics.org/releases/cairo-1.12.2.tar.xz
    
    

    cairo 依赖 libpngpixman,所以需要安装这两个

    yum -y install libpng*  pixman*
    

    注,有可能这样安装的 pixman 的版本不对,需要需要源码安装

    源码安装 pixman:

    wget http://cairographics.org/releases/pixman-0.22.0.tar.gz
    tar -zxvf pixman-0.22.0.tar.gz
    ./configure --prefix=/usr/local
    make && make install
    

    注:这里 pixman 的安装必需要加个 prefix=/usr/local,不然的话,cairo 会找不到再次表示蛋疼。

    安装 cairo 的正确姿势:

    tar -zxvf cairo-1.12.2.tar.xz
    cd cairo-1.12.2
    ./configure
    make && make install
    

    安装 py2cairo 的正确姿势:

    安装的时候需要明确下 pkgconfig 的位置和 Python 的包路径:

    cd py2cairo
    export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH
    PYTHONPATH="/usr/local/lib/python2.7/site-packages/:$PYTHONPATH"
    LDFLAGS="-lm -ldl -lutil" ./waf configure --prefix=/usr/local
    ./waf build
    ./waf install
    

    经历九九八十一难,终于安装完成。

    注:真的是最麻烦的就是 py2cairo 这个家伙,开始折腾了我一天没有安装好,没有安装好就无法出图。。。

  4. 安装 Graphite 三大件

    pip install whisper carbon graphite-web
    
  5. 安装数据采集工具 Diamond

    git clone https://github.com/BrightcoveOS/Diamond
    cd Diamond
    

    修改 Diamond 的配置文件:

    cd Diamond
    cp conf/diamond.conf.example conf/diamond.conf
    

    diamond.conf 配置文件如下:

    #
    #Diamond Configuration File
    ### Options for the server
    [server]
    # Handlers for published metrics.
    handlers = diamond.handler.graphite.GraphiteHandler, diamond.handler.archive.ArchiveHandler
    # User diamond will run as
    # Leave empty to use the current user
    user =
    # Group diamond will run as
    # Leave empty to use the current group
    group =
    # Pid file
    pid_file = /var/run/diamond.pid
    # Directory to load collector modules from
    # 这个和你的 Diamond 安装路径有关
    collectors_path = /root/Diamond/src/collectors/
    # Directory to load collector configs from
    # 这个和你的 Diamond 安装路径有关
    collectors_config_path = /root/Diamond/src/collectors/
    # Directory to load handler configs from
    # 这个和你的 Diamond 安装路径有关
    handlers_config_path = /root/Diamond/src/diamond/handler
    handlers_path = /root/Diamond/src/diamond/handler
    # Interval to reload collectors
    collectors_reload_interval = 3600
    ### Options for handlers
    [handlers]
    # daemon logging handler(s)
    keys = rotated_file
    ### Defaults options for all Handlers
    [[default]]
    [[ArchiveHandler]]
    # File to write archive log files
    #需要创建 /var/log/diamond/ 目录
    log_file = /var/log/diamond/archive.log
    # Number of days to keep archive log files
    days = 7
    [[GraphiteHandler]]
    ### Options for GraphiteHandler
    # Graphite server host
    host = 127.0.0.1
    # Port to send metrics to
    port = 2003
    # Socket timeout (seconds)
    timeout = 15
    # Batch size for metrics
    batch = 1
    [[GraphitePickleHandler]]
    ## Options for GraphitePickleHandler
    # Graphite server host
    host = 127.0.0.1
    # Port to send metrics to
    port = 2004
    # Socket timeout (seconds)
    timeout = 15
    # Batch size for pickled metrics
    batch = 256
    [[MySQLHandler]]
    ### Options for MySQLHandler
    # MySQL Connection Info
    hostname    = 127.0.0.1
    port        = 3306
    username    = root
    password    =
    database    = diamond
    table       = metrics
    # INT UNSIGNED NOT NULL
    col_time    = timestamp
    # VARCHAR(255) NOT NULL
    col_metric  = metric
    # VARCHAR(255) NOT NULL
    col_value   = value
    [[StatsdHandler]]
    host = 127.0.0.1
    port = 8125
    [[TSDBHandler]]
    host = 127.0.0.1
    port = 4242
    timeout = 15
    [[LibratoHandler]]
    user = [email protected]
    apikey = abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz01
    [[HostedGraphiteHandler]]
    apikey = abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz01
    timeout = 15
    batch = 1
    # And any other config settings from GraphiteHandler are valid here
    [[HttpPostHandler]]
    ### Urp to post the metrics
    url = http://localhost:8888/
    ### Metrics batch size
    batch = 100
    ### Options for collectors
    [collectors]
    [[default]]
    ### Defaults options for all Collectors
    # Uncomment and set to hardcode a hostname for the collector path
    # Keep in mind, periods are seperators in graphite
    # hostname = my_custom_hostname
    # If you prefer to just use a different way of calculating the hostname
    # Uncomment and set this to one of these values:
    # smart             = Default. Tries fqdn_short. If that's
    localhost, uses hostname_short
    # fqdn_short        = Default. Similar to hostname -s
    # fqdn              = hostname output
    # fqdn_rev          = hostname in reverse (com.example.www)
    # uname_short       = Similar to uname -n, but only the first part
    # uname_rev         = uname -r in reverse (com.example.www)
    # hostname_short    = `hostname -s`
    # hostname          = `hostname`
    # hostname_rev      = `hostname` in reverse (com.example.www)
    # shell             = Run the string set in hostname as a shell command and use its
    #                     output(with spaces trimmed off from both ends) as the hostname.
    # hostname_method = smart
    # Path Prefix and Suffix
    # you can use one or both to craft the path where you want to put metrics
    # such as: %(path_prefix)s.$(hostname)s.$(path_suffix)s.$(metric)s
    # path_prefix = servers
    # path_suffix =
    # Path Prefix for Virtual Machines
    # If the host supports virtual machines, collectors may report per
    # VM metrics. Following OpenStack nomenclature, the prefix for
    # reporting per VM metrics is "instances", and metric foo for VM
    # bar will be reported as: instances.bar.foo...
    # instance_prefix = instances
    # Default Poll Interval (seconds)
    # interval = 300
    ### Options for logging
    # for more information on file format syntax:
    # http://docs.python.org/library/logging.config.html#configuration-file-format
    [loggers]
    keys = root
    # handlers are higher in this config file, in:
    # [handlers]
    # keys = ...
    [formatters]
    keys = default
    [logger_root]
    # to increase verbosity, set DEBUG
    level = INFO
    handlers = rotated_file
    propagate = 1
    [handler_rotated_file]
    class = handlers.TimedRotatingFileHandler
    level = DEBUG
    formatter = default
    # rotate at midnight, each day and keep 7 days
    args = ('/var/log/diamond/diamond.log', 'midnight', 1, 7)
    [formatter_default]
    format = [%(asctime)s] [%(threadName)s] %(message)s
    datefmt =
    ### Options for config merging
    # [configs]
    # path = "/etc/diamond/configs/"
    # extension = ".conf"
    #Example:
    # /etc/diamond/configs/net.conf
    # [collectors]
    #
    # [[NetworkCollector]]
    # enabled = True
    

    启动 Diamond:

    python diamond -c ../conf/diamond.conf
    

启动 Grapgite 三大件

初始化 Graphite 数据库:

cd /opt/graphite/webapp/graphite
mv local_settings.py.example local_settings.py

修改 local_settings.py 里面的数据库配置,把下面一段的注释取消:

DATABASES = {
    'default': {
        'NAME': '/opt/graphite/storage/graphite.db',
        'ENGINE': 'django.db.backends.sqlite3',
        'USER': 'root',
        'PASSWORD': '123456',
        'HOST': '',
        'PORT': ''
    }
}

初始化 Graphite 数据库:

python manage.py syncdb

注:在这个初始化的过程中就可能遇到的错误是 tagging 版本太低,或者是 django 的版本问题,所以才有前面的 django 的版本必须为 1.4,tagging 的版本必须为 0.3.1

启动 carbon-cache:

cd /opt/graphite/bin
./carbon-cache.py start

注:这个在启动过程中,可能遇到如下错误:

from carbon.util import run_twistd_plugin
File “/opt/graphite/lib/carbon/util.py”, line 19, in <module>
from twisted.scripts._twistd_unix import daemonize
ImportError: cannot import name daemonize

解决方法是修改 /opt/graphite/lib/carbon/util.py 文件,把其 from twisted.scripts._twistd_unix import daemonize 替换成 import daemonize

注:需要安装 daemonize,pip install daemonize

然后再次启动即可

启动 graphite,使用 wsgi 启动,在 /opt/graphite/webapp 下新建一个文件 wsgi.py 和一个配置文件 django.xml

wsgi.py

import os,sys

if not os.path.dirname(__file__) in sys.path[:1]:
    sys.path.insert(0, os.path.dirname(__file__))
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

from django.core.handlers.wsgi import WSGIHandler
application = WSGIHandler()

django.xml

<uwsgi>
    <socket>ip:port</socket>
        <chdir>/opt/graphite/webapp/graphite</chdir> 
        <pythonpath>..</pythonpath>
    <module>wsgi</module>
</uwsgi>

启动:

uwsgi -x django.xml

现在可以愉快的访问了 http://ip:port

建议:不作死就不会死,要安装这个还是不要用 CentOS 5.8 了,太痛苦。。使用 Python 的 virtualenv 环境也会遇到很多问题。

比如使用 virtualenv 最新版本的时候,会遇到这个错误:

  OSError: Command /Users/bgbb/Developer/django/vnv/bin/python -c "import sys, pip;   sys...d\"] + sys.argv[1:]))" setuptools pip failed with error code 2

解决办法是降级到 virtualenv 1.10.1 版本:

  pip uninstall virtualenv
  wget  https://pypi.python.org/packages/source/v/virtualenv/virtualenv-1.10.1.tar.gz --no-check-certificate
  python setup.py install

如果大家安装过程中遇到问题,欢迎交流!

注:该安装方法适用于 CentOS 5.8,其他的版本应该不会遇到我这么多问题。
