时间：2022-02-13 00:31:14

升级ruby版本，有时候安装ruby的版本过低，需要进行升级，例如安装在centos6.7安装fpm需要ruby版本在1.9以上。

0x00 主机环境如下

[root@test ~]# cat /etc/redhat-release 
CentOS release 6.7 (Final)

[root@test ~]# uname -r

2.6.32-573.el6.x86_64

0x01 使用yum安装ruby

[root@web ~]# yum install rubygems ruby-devel

0x02 查看ruby的版本

[root@web ~]# ruby -v

ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux]

0x03 升级ruby1.9.3版本

1）删除原来的rubygems仓库

[root@web ~]# gem sources --remove http://rubygems.org/

2）添加aliyun的rubygems仓库

[root@web ~]# gem sources -a http://mirrors.aliyun.com/rubygems/

3）查看rubygems仓库

[root@web ~]# gem sources -l

*** CURRENT SOURCES ***

http://mirrors.aliyun.com/rubygems/

4）使用RVM进行升级ruby

a:在rvm官方网址：https://rvm.io/执行如下命令：

[root@web ~]#  gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

gpg: requesting key D39DC0E3 from hkp server keys.gnupg.net

gpg: requesting key 39499BDB from hkp server keys.gnupg.net

gpg: key D39DC0E3: "Michal Papis (RVM signing) <mpapis@gmail.com>" not changed

gpg: key 39499BDB: public key "Piotr Kuczynski <piotr.kuczynski@gmail.com>" imported

gpg: no ultimately trusted keys found

gpg: Total number processed: 2

gpg:               imported: 1  (RSA: 1)

gpg:              unchanged: 1

b:接着执行如下命令：

[root@web ~]# \curl -sSL https://get.rvm.io | bash -s stable

Downloading https://github.com/rvm/rvm/archive/1.29.3.tar.gz

curl: (35) SSL connect error

Could not download 'https://github.com/rvm/rvm/archive/1.29.3.tar.gz'.

  curl returned status '35'.

Downloading https://bitbucket.org/mpapis/rvm/get/1.29.3.tar.gz

Downloading https://bitbucket.org/mpapis/rvm/downloads/1.29.3.tar.gz.asc

curl: (7) couldn't connect to host

Could not download 'https://bitbucket.org/mpapis/rvm/downloads/1.29.3.tar.gz.asc'.

  curl returned status '7'.

Creating group 'rvm'

Installing RVM to /usr/local/rvm/

Installation of RVM in /usr/local/rvm/ is almost complete:

  * First you need to add all users that will be using rvm to 'rvm' group,

    and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

  * To start using RVM you need to run `source /etc/profile.d/rvm.sh`

    in all your open shell windows, in rare cases you need to reopen all shell windows.

c:执行上述命令 * To start using RVM you need to run `source /etc/profile.d/rvm.sh`

[root@web ~]# source /etc/profile.d/rvm.sh
