如何升级ruby的版本
如何升级ruby的版本
升级ruby版本，在配置Redis集群时有提示报错，提示安装ruby的版本过低，需要进行升级，例如安装在centos7.5安装需要ruby版本在 2.2.2以上。
1、主机环境如下：
[root@localhost bin]# cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core) [root@localhost bin]# uname -r 3.10.0-862.el7.x86_64
2、使用yum安装ruby
[root@localhost ~]# yum install rubygems ruby-devel
已加载插件：fastestmirror, langpacks

完毕！
3、查看ruby的版本
[root@localhost ~]# ruby -v ruby 2.0.0p648 (2015-12-16) [x86_64-linux]
4、升级ruby 2.0.0 到2.2.2以上版本
1）删除原来的rubygems仓库
[root@localhost ~]# gem sources --remove http://rubygems.org/
2）添加aliyun的rubygems仓库
[root@localhost ~]# gem sources -a http://mirrors.aliyun.com/rubygems/
3）查看rubygems仓库
1 [root@localhost ~]# gem sources -l 2 *** CURRENT SOURCES *** 3 4 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@localhost ~]# 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@localhost ~]# \curl -sSL https://get.rvm.io | bash -s stable
Downloading https://github.com/rvm/rvm/archive/1.29.6.tar.gz
Downloading https://github.com/rvm/rvm/releases/download/1.29.6/1.29.6.tar.gz.asc
gpg: 于 2018年12月13日 星期四 23时09分53秒 CST 创建的签名，使用 RSA，钥匙号 39499BDB
gpg: 完好的签名，来自于“Piotr Kuczynski <piotr.kuczynski@gmail.com>”
gpg: 警告：这把密钥未经受信任的签名认证！
gpg: 没有证据表明这个签名属于它所声称的持有者。

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.
* Please do NOT forget to add your users to the rvm group.
The installer no longer auto-adds root or users to the rvm group. Admins must do this.
Also, please note that group memberships are ONLY evaluated at login time.
This means that users must log out then back in before group membership takes effect!
c:执行上述命令 * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
[root@localhost ~]# source /etc/profile.d/rvm.sh
5、查看RVM可安装的ruby的版本
[root@localhost ~]# rvm list known
Warning, new version of rvm available '1.29.7', you are using older version '1.29.6'.
You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc
You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc

6、安装ruby 2.4.1版本
[root@localhost ~]# rvm install ruby 2.4.1
Warning, new version of rvm available '1.29.7', you are using older version '1.29.6'.
You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc

7、查看ruby是否升级成功
[root@localhost ~]# ruby -v
ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]
至此，ruby版本升级成功
如果有错误，欢迎各位网友指导。
