网络设备自动备份

参考链接：https://github.com/ytti/oxidized
测试环境：CentOS Linux release 7.3.1611 (Core)
主要组件：oxidized oxidized-script oxidized-web
注意：oxidized-web需要ruby2.3以上支持，如不安装oxidized-web，配置文件里rest 修改为false

安装依赖组件

• yum 源修改：本测试环境为办公网测试机，需要修改yum源，通常建议修改为公司线上或测试环境yum源（可找业务运维帮忙倒出上传到/etc/yum.repos.d）
  yum install make cmake which sqlite-devel openssl-devel libssh3-devel ruby gcc ruby-devel libicu-devel gcc-c++

  安装ruby

  centos7默认ruby为2.0版本，需要单独安装。
  yum install centos-release-scl
  yum-config-manager --enable rhel-server-rhscl-7-rpms
  yum install -y rh-ruby25-ruby-devel
  yum install rh-ruby25
  scl enable rh-ruby25 bash
  ruby -v
  ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-linux]
  cp /opt/rh/rh-ruby25/root/usr/lib64/libruby.so.2.5 /usr/lib/
  设置登录时自动启动ruby2.5：
  vim /etc/profile.d/rh-ruby25.sh
  #!/bin/bash
  source /opt/rh/rh-ruby25/enable
  export X_SCLS="scl enable rh-ruby25 'echo $X_SCLS'"
  export PATH=$PATH:/opt/rh/rh-ruby25/root/usr/local/bin

  安装oxidized

  gem install oxidized
  gem install oxidized-script oxidized-web
  useradd -m -d /home/oxidized oxidized
  cp /opt/rh/rh-ruby25/root/usr/local/share/gems/gems/oxidized-0.24.0/extra/oxidized.service /lib/systemd/system
  mkdir -p /home/oxidized/.config/oxidized
  mkdir /home/oxidized/.config/oxidized/logs/
  mkdir /home/oxidized/.config/oxidized/configs
  chown oxidized:oxidized /home/oxidized/.config/oxidized

  router.db 文件

  vim home/oxidized/.config/oxidized/router.db
  172.18.31.11:comware:user:passwd

  启动服务

  systemctl restart oxidized.service
  systemctl status oxidized.service
  至此，自动备份基础功能已完成，可在目录里查看备份的配置文件，接下来配置可用web页面查看比较直观。

  安装nginx

yum install nginx
vim /etc/nginx/conf.d/oxidized.conf
cat /etc/nginx/conf.d/oxidized.conf

server {
listen 80;
server_name 172.18.34.45;
location / {
proxy_pass http://127.0.0.1:8888/;
}

access_log /var/log/nginx/access_oxidized.log;
error_log /var/log/nginx/error_oxidized.log;
}
systemctl restart nginx.service

• 浏览器打开：http://172.18.34.45/nodes
• Actions 下有3个图标，第一个点开可看到配置文件。
• 第二个versions可查看每个版本的配置差异。（需要git支持，安装步骤见下文）
• 第三个为强制备份。
  默认显示时间不对，需要修改以下配置文件。
  vim /opt/rh/rh-ruby25/root/usr/local/share/gems/gems/oxidized-web-0.11.1/lib/oxidized/web/public/scripts/oxidized.js

  git 安装

  yum -y install git
  yum install libgit2
  git config user.name Oxidized
  git config user.email "o@example.com"

  修改配置文件为git输出

  systemctl restart oxidized.service
  systemctl status oxidized.service
  通过区域按钮可查看每个版本配置差异。
