The following main references Zhang Shanyu's article (http://www.cnblogs.com/shanyou/archive/2012/10/11/2720597.html)

安装脚本将Mono安装到了/opt/mono-20150520032320/，需要将Mono的目录加入系统$PATH变量

Method One: Add the variable "to all users (permanent)" in the/etc/profile file
Using VI to add a variable to the file/etc/profile file, the variable will be valid for all users under Linux and is "permanent".

Vi/etc/profile

Add the following two lines of code at the end of the file

Path=/opt/mono-20150520032320/bin:$PATH  export PATH

The modification takes effect and requires executing the following code (otherwise restarting reboot)

Source/etc/profile

Method Two: Create a mono configuration in the/etc/profile.d/directory

cd/etc/profile.d/

Create a new mono.sh

VI mono.sh

Write something inside this file

Export path=$PATH:/opt/mono-20150520032320/bin

The "mono-20150520032320" in the path is shown above, and if you need to configure the update version then the path is available.

The modification takes effect and requires the following code to be executed

SOURCE mono.sh

Now you can execute Mono's command directly.

Mono-4.1.0 (tarball Tue may 23:45:50 EDT2002-2014 Novell, INC, Xamarin Inc and Contributors. WW w.mono-project.com        TLS:           __thread        SIGSEGV:       altstack        notifications:epoll        Architecture:  amd64        Disabled:      none        Misc:          softdebug        LLVM:          supported, not Enabled.        GC:            sgen

The execution results are consistent. Mono installation is complete.
