夜莺监控v5版本

夜莺监控v5

1.单机夜莺

官网提供了一键部署的脚本 前题是root权限和centos系统

# 安装脚本做了3件事情
# 1. 安装promethues作为存储，夜莺支持对接多种存储，我们选择单机版Prometheus来快速开始
# 2. 安装mysql，root默认密码为1234
# 3. 安装n9e-server
curl -s http://116.85.64.82/install_n9e_server.sh|bash

# 进程如果启动了，理论上会监听2个端口，一个http端口一个rpc端口
# 通过下面命令可以查看端口是否在监听，如果端口都在监听，就说明启动成功
ss -tlnp|grep n9e-server

2.脚本内容

脚本的内容 如果没有外网根据脚本自行调节

#!/bin/bash

# 1.安装promethues作为存储，夜莺支持对接多种存储，我们选择单机版Prometheus来快速开始
#yum install wget -y &>/dev/null  
mkdir -p /opt/prometheus
wget https://s3-gz01.didistatic.com/n9e-pub/prome/prometheus-2.28.0.linux-amd64.tar.gz -O prometheus-2.28.0.linux-amd64.tar.gz
tar xf prometheus-2.28.0.linux-amd64.tar.gz
cp -far prometheus-2.28.0.linux-amd64/*  /opt/prometheus/

# service

systemctl daemon-reload
systemctl enable prometheus
systemctl restart prometheus
systemctl status prometheus

# 2.安装mysql，root默认密码为1234
yum -y install mariadb*
# 假设机器的/home分区是个SSD的大分区，datadir设置为/home/mysql
# mkdir -p /home/mysql
# chown mysql:mysql /home/mysql
# sed -i '/^datadir/s/^.*$/datadir=\/home\/mysql/g' /etc/my.cnf
# 启动mysql进程
systemctl start mariadb.service
# 将mysql设置为开机自启动
systemctl enable mariadb.service
# 设置mysql root密码
mysql -e "SET PASSWORD FOR 'root'@'localhost' = PASSWORD('1234');"

# 3.安装n9e-server
mkdir -p /opt/n9e
cd /opt/n9e
wget 116.85.64.82/n9e-server-5.0.0-rc3.tar.gz
tar zxvf n9e-server-5.0.0-rc3.tar.gz
mysql -uroot -p1234 < /opt/n9e/server/sql/n9e.sql

cp /opt/n9e/server/etc/service/n9e-server.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable n9e-server
systemctl restart n9e-server
systemctl status n9e-server

3.安装完成

安装成功之后，就可以用浏览器访问服务端的端口（在服务端的yml配置中可以看到http的监听端口，默认是8000）进入系统了，系统启动的时候会默认初始化一个`root`账号，密码是`root.2020` 登录之后没啥数据，毕竟我们还没有部署采集程序，下一小节开始部署客户端采集程序。

4.部署客户端

# 一键安装n9e-agentd
curl -s http://116.85.64.82/install_n9e_agentd.sh|bash

# 通过下面命令查看n9e-agentd的进程，如果进程存在，说明启动成功
# 如果启动失败，可通过 journalctl -u n9e-agentd -f 查看日志
ps -ef|grep n9e-agentd|grep -v grep

修改/opt/n9e/agentd/etc/agentd.yaml中的服务端连接地址（搜索endpoint关键字），然后重启n9e-agentd即可，重启命令 systemctl restart n9e-agentd  

5.安装客户端代码内容

#!/bin/bash

# install n9e-agentd
#yum install wget -y &>/dev/null  
mkdir -p /opt/n9e
cd /opt/n9e
wget 116.85.64.82/n9e-agentd-344a75d.tar.gz
tar zxvf n9e-agentd-344a75d.tar.gz

cp /opt/n9e/agentd/systemd/n9e-agentd.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable n9e-agentd
systemctl restart n9e-agentd
systemctl status n9e-agentd
