CentOS7通過持續整合包安裝最新的Mono

Mono 3.6.0 釋出，此版本從上一個版本開始，總共提交了 878 個commits。自2014 年 3 月 10 日開始，共有66 位貢獻者參與開發； 其中有22位首次提交的貢獻值，他們修復了 112 個 bug，具體請看《Mono 3.6釋出，支援在Mac系統使用Nuget》。 Mono的官方網站也進行了更新，介面清新。其中在下載頁面只有OSX下的框架是最新的，其他平臺的包還在測試中，可以通過原始碼安裝，也可以通過官方的持續整合包進行安裝，可參考文件 Continuous Integration packages。

Linux 平臺包分兩個發行版系列： Debian 系（支援 Debian 7+, Ubuntu 11.04+, Mint 11+, Elementary 0.2+ 等）和 Red Hat（支援CentOS 7+, Mageia 3+, Fedora 19+, openSUSE 12.3+等）。

下面介紹CentOS 7上安裝最新的Mono 3.8.1:

1、新增Mono的 包庫源：

把Mono Project public Jenkins GPG signing  匯入系統：

wget http://jenkins.mono-project.com/repo/xamarin.gpg

rpm --import xamarin.gpg

yum-config-manager --add-repo http://jenkins.mono-project.com/repo/centos/

2、通過包管理器查詢mono-snapshot找到可以安裝最新的包

yum search mono-snapshot

[mono-20140816130953][root@localhost jexus-5.6.1]#yum search mono-snapshot

mono-snapshot-latest.noarch : Mono runtime snapshot - latest version metapackage

mono-snapshot-XXXXXXXXX 表示特定版本的包, mono-snapshot-latest 是最新版本的包，安裝 mono-snapshot-latest，包管理器可以把包更新到最新. 所有的安裝包裡都帶了一個工具mono-snapshot

[root@localhost ~]# mono-snapshot 

This script will help you to set up your environment to use a 

snapshot package of Mono. To use it, run:

        . mono-snapshot APP/VER

You have the following possible combinations of APP/VER:

        mono/20140816130953

Calling APP without specifying VER will load the latest version

我們看到系統裡安裝了一個版本20140816130953， 

3、yum -y install mono-snapshot-latest 

[root@localhost src]# yum -y install mono-snapshot-latest

使用mono-snapshot 工具看下我們安裝好的Mono的最新版本是3.8.1：

[root@localhost ~]# . mono-snapshot mono
[mono-20140816130953][root@localhost ~]# mono --version
Mono JIT compiler version 3.8.1 (tarball Sat Aug 16 16:20:35 EDT 2014)

請注意mono-snapshot 前邊的 “.”.

4、讓Jexus 使用最新的Mono 

修改Jexus指令碼把最新的mono 路徑加入進去，如下圖

[mono-20140816130953][root@localhost ~]# cd /usr/jexus/
[mono-20140816130953][root@localhost jexus]# vi jws
[mono-20140816130953][root@localhost jexus]# service jws restart
Restarting jws (via systemctl):                            [  確定  ]
[mono-20140816130953][root@localhost jexus]#

將Jexus 新增為系統服務的指令碼參見《Centos 7.0 安裝Mono 3.4 和 Jexus 5.6》。
