centos7安装oxidized备份软件

首先需要提前下载ruby，因为默认yum安装的版本太低

https://cache.ruby-lang.org/pub/ruby/3.1/ruby-3.1.0.tar.gz

1、yum remove ruby ruby-devel（有就卸载，没有则忽略）

2、将下载好的ruby包解压到/opt下

复制代码

[root@oxidized ruby-3.1.0]# pwd
/opt/ruby-3.1.0

3、安装依赖

复制代码

[root@oxidized ruby-3.1.0] yum install make cmake which sqlite-devel openssl-devel libssh2-devel  gcc  libicu-devel gcc-c++  -y

4、进入ruby安装目录编译安装

复制代码

[root@oxidized ruby-3.1.0]# ./configure
[root@oxidized ruby-3.1.0]# make
[root@oxidized ruby-3.1.0]# make install
[root@oxidized ruby-3.1.0]# which ruby
/usr/local/bin/ruby
检查ruby版本：
[root@oxidized ruby-3.1.0]# ruby -v
ruby 3.1.0p0 (2021-12-25 revision fb4df44d16) [x86_64-linux]
[root@oxidized ruby-3.1.0]# yum install rubygems -y
[root@oxidized ~]# gem -v
2.0.14.1

5、安装oxidized

复制代码

[root@oxidized ruby-3.1.0]# gem install oxidized
报错没有源，添加源
[root@oxidized ~]# gem sources --add https://mirrors.tuna.tsinghua.edu.cn/rubygems/
Error fetching https://mirrors.tuna.tsinghua.edu.cn/rubygems/:
        SSL_connect returned=1 errno=0 state=error: certificate verify failed (https://mirrors.tuna.tsinghua.edu.cn/rubygems/specs.4.8.gz)
[root@oxidized ~]# gem sources -l
*** CURRENT SOURCES ***

[root@oxidized ~]# gem sources -a https://rubygems.org/
Error fetching https://rubygems.org/:
        SSL_connect returned=1 errno=0 state=error: certificate verify failed (https://rubygems.org/specs.4.8.gz)
[root@oxidized ~]# gem sources -a http://rubygems.org/
https://rubygems.org is recommended for security over http://rubygems.org/

Do you want to add this insecure source? [yn]  y
Error fetching http://rubygems.org/:
        server did not return a valid file (http://rubygems.org/specs.4.8.gz)

试了几种源都是不行的(部署时环境的网络有问题，后来切换了网段就好了)

解决方法：

复制代码

找到.gemrc文件，添加源
[root@oxidized ~]# find /* -name '*gemrc*'
/root/.config/gem/gemrc
/root/.gemrc

[root@oxidized ~]# vim /root/.gemrc
---
:backtrace: false
:bulk_threshold: 1000
:sources:
- http://mirrors.tuna.tsinghua.edu.cn/rubygems/
:update_sources: true
:verbose: true
保存退出，再次查看就能看到添加上了
[root@oxidized ~]# gem sources
*** CURRENT SOURCES ***

http://mirrors.tuna.tsinghua.edu.cn/rubygems/

再次尝试安装，报错：

CMake 3.5.1 or higher is required. You are running version 2.8.12.2

6、升级cmake

复制代码

1、移除老版本，并下载依赖
[root@oxidized cmake-3.7.2]#  yum remove cmake -y ; yum install -y gcc gcc-c++ make automake openssl openssl-devel
2、下载安装包并解压
[root@oxidized cmake-3.7.2]# wget https://cmake.org/files/v3.7/cmake-3.7.2.tar.gz ; tar -zxf cmake*.tar.gz
3、编译、安装
[root@oxidized cmake-3.7.2]# cd cmake* ; ./bootstrap ; gmake -j `grep 'processor' /proc/cpuinfo | wc -l` ; gmake install
4、查看编译后的cmake版本并创建连接，最后查看cmake版本
[root@oxidized cmake-3.7.2]# /usr/local/bin/cmake --version
[root@oxidized cmake-3.7.2]# ln -s /usr/local/bin/cmake /usr/bin/
[root@oxidized cmake-3.7.2]# cmake --version
cmake version 3.7.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

再次执行安装oxidized

成功了，再安装oxidized-script，oxidized-web

OK了~！

复制代码

[root@oxidized cmake-3.7.2]# oxidized
edit ~/.config/oxidized/config
查看默认配置文件
[root@oxidized cmake-3.7.2]# cat ~/.config/oxidized/config
