Psdash主机监控面板搭建
官方发布地址： https://github.com/wenguonideshou/psdash_HTTPBasicAuth
简介：在psdash的基础上添加httpbasicauth（也就是打开页面弹出提示框，要输入用户名密码），界面翻译为中文，增加展示所有节点基本状态的主界面，可以理解为psdash的中文版分支
功能：psdash是基于psutil、zerorpc的python语言开发的主机监控面板，本分支包含psdash的所有功能—支持多节点/集群部署，所有数据每3秒自动更新，无需手动刷新页面；
总览页：支持查看 cpu, disks, network, users, memory, swap , network
进程：进程列表，并展示每个进程详情，包括打开的文件数、打开的连接数、内存占用、子进程、资源限制
硬盘：所有硬盘和分区
网络：所有网络接口和使用的流量，以及当前的网络连接
日志：展现自定义的日志文件详情，并支持搜索文件内容
Debian/Ubuntu:
apt-get install build-essential python-dev -y
apt-get install python-setuptools -y
pip install psdash --allow-external argparse
如果上面的命令安装不成功则执行下面的命令
git clone https://github.com/Jahaja/psdash.git
cd psdash
pip install -U setuptools 若报错 先执行 apt-get install python-pip
python setup.py install
RHEL (Fedora, CentOS):
节点和agent节点都执行下面的命令(安装psdash)
yum groupinstall "Development Tools" -y
yum install python-devel -y
yum install python-setuptools -y
git clone https://github.com/Jahaja/psdash.git
cd psdash
pip install -U setuptools 若报错 先执行 yum install -y python-pip
pip install -U setuptools
python setup.py install
pip install flask-httpauth
git clone https://github.com/wenguonideshou/psdash_HTTPBasicAuth.git
cd psdash_HTTPBasicAuth
python run.py -l '/var/log/**/*.log'
在run.py的app=Flask(name)下面添加如下语句：
app.config.xxx = yyy
xxx为下面的参数，yyy为值，比如：
app.config.PSDASH_ALLOWED_REMOTE_ADDRESSES = "10.0.0.2, 192.29.20.2"
app.config.PSDASH_URL_PREFIX = "/psdash"
app.config.PSDASH_LOG_LEVEL = logging.INFO
app.config.PSDASH_LOG_LEVEL = "%(levelname)s"
app.config.PSDASH_NODES = [{'name': 'mywebnode', 'host': '10.0.0.2', 'port': 5000}]
app.config.PSDASH_NET_IO_COUNTER_INTERVAL = 3
app.config.PSDASH_LOGS_INTERVAL = 60
app.config.PSDASH_REGISTER_INTERVAL = 60
app.config.PSDASH_LOGS = ['/var/log/*.log']
app.config.PSDASH_REGISTER_TO = 'http://10.0.20.2:5000'
app.config.PSDASH_REGISTER_AS = 'myvps'
app.config.PSDASH_HTTPS_KEYFILE = '/home/user/private.key'
app.config.PSDASH_HTTPS_CERTFILE = '/home/user/certificate.crt'
app.config.PSDASH_ENVIRON_WHITELIST = ['HOME']
本次主节点为192.168.2.3，添加内容如下
app.config.PSDASH_URL_PREFIX = "/psdash"
app.config.PSDASH_LOG_LEVEL = logging.INFO
app.config.PSDASH_LOG_LEVEL = "%(levelname)s"
app.config.PSDASH_NODES = [{'HOME': 'mywebnode', 'host': '192.168.2.3', 'port': 5000}]
app.config.PSDASH_NET_IO_COUNTER_INTERVAL = 3
app.config.PSDASH_LOGS_INTERVAL = 60
app.config.PSDASH_REGISTER_INTERVAL = 60
app.config.PSDASH_LOGS = ['/var/log/*.log']
app.config.PSDASH_REGISTER_TO = 'http://192.168.2.3:5000'
app.config.PSDASH_REGISTER_AS = 'myvps'
详细参数详见：https://github.com/Jahaja/psdash#configuration
#创建screen.sh
#!/bin/bash
cd /root/psdash_HTTPBasicAuth
screen -dmS psdash python run.py -l '/var/log/**/*.log'
chmod +x screen.sh
#添加开机启动
vi /etc/rc.d/rc.local
#在最后一行添加如下字段
sh /root/psdash/psdash_HTTPBasicAuth/screen.sh
#赋予可执行权限
chmod +x /etc/rc.d/rc.local
#然后重启
reboot
修改web.py里的users = {“admin”: “admin”,} 前面是用户名后面是密码，可以添加多个用户
#在psdash目录下创建screen.sh
#!/bin/bash
cd /root/psdash
screen -dmS psdash psdash -a --register-as woniu -l '/var/log/**/*.log' --register-to http://192.168.2.3:5000
chmod +x screen.sh
#添加开机启动
vi /etc/rc.d/rc.local
在最后一行添加如下字段
sh /root/psdash/screen.sh
#赋予可执行权限
chmod +x /etc/rc.d/rc.local
#然后重启
reboot
