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 libssh2-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

config 文件

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 “[e-mail]”

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。
