1. 基础软件包安装
yum -y install libcurl libcurl-devel rrdtool rrdtool-devel perl-rrdtool rrdtool-prel libgcrypt-devel gcc make gcc-c++ liboping liboping-devel perl-CPAN net-snmp net-snmp-devel python-devel

yum install python-pip 
（若安装不成功，首先安装epel扩展源：

sudo yum -y install epel-release

然后再安装pip）

#安装java 1.8

#for mysql
yum install mysql-devel.x86_64
pip install MySQL-python
pip install DBUtils


#for redis
pip install redis

#for memcache
pip install python-memcached

#for rabbit
pip install pika
pip install requests




2.collectd 安装
./configure --with-data-max-name-len=512 --enable-debug
make; make install


3.自定义python插件安装
将python脚本与jar包 放到指定目录
python: /opt/collectd/include/python
jar: /opt/collectd/share/collectd/java/jmx-monitor.jar

4.配置自定义插件
LoadPlugin python (启用python插件模块)

<Plugin python>

        <Module PyZK>
               hosts '192.168.102.76,192.168.102.45'
               port 2181
        </Module>

        	# memcached采集
