Preface

After trying to install mono on the Internet, this installation process went through about two weeks and tried various versions and all the installation methods described by the blogs. You can try different versions of mono by installing the following content. And standard installation in informal environments.

1. install the required Library

yum -y install wget glib2-devel libtiff libtiff-devel libjpeg libjpeg-devel giflib giflib-devel libpng libpng-devel libX11 libX11-devel freetype freetype-devel fontconfig fontconfig-devel libexif libexif-devel gcc-c++ gettext unzip zip bzip2 bzip2-devel curl-devel gtk2-devel boost-devel

2. add an rpm source

rpm --import "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF"yum-config-manager --add-repo http://jenkins.mono-project.com/repo/centos/

3. search for available versions

yum search mono-snapshot

4. select to install the latest snapshot.

yum -y install mono-snapshot-latest

Ps: If you want to install a snapshot of a certain version, the command is

yum -y install mono-snapshot-XXXXXXXXX

5. View available Mono snapshots

mono-snapshot

The result is as follows:

This script will help you to set up your environment to use asnapshot package of Mono. To use it, run:        . mono-snapshot APP/VERYou have the following possible combinations of APP/VER:        mono/20150520032320Calling APP without specifying VER will load the latest version

 

6. execute the specified snapshot

Mono-snapshot mono or mono-snapshot mono/XXXXXXXXX

Display result:

[Mono-20150520032320] [root @ localhost ~] # Mono-20150520032320 indicates the snapshot used by mono

7. check whether Mono is successfully installed.

mono --version

Display result:

Mono JIT compiler version 4.1.0 (tarball Tue May 19 23:45:50 EDT 2015)Copyright (C) 2002-2014 Novell, Inc, Xamarin Inc and Contributors. www.mono-project.com        TLS:           __thread        SIGSEGV:       altstack        Notifications: epoll        Architecture:  amd64        Disabled:      none        Misc:          softdebug        LLVM:          supported, not enabled.        GC:            sgen

8. set Mono environment variables on CentOS

Use the find/-name 'libmonoposixhelper. so' command to find the installation address of the version;

find / -name 'libMonoPosixHelper.so'/opt/mono-20150520032320/lib/libMonoPosixHelper.so

Write down/opt/mono-20150520032320 (used below)

If multiple versions are installed, multiple records are generated.

The following content mainly refer to the article (http://www.cnblogs.com/shanyou/archive/2012/10/11/2720597.html)

The installation script installs Mono/Opt/mono-20150520032320/, you need to add the Mono directory to the system $ PATH variable

Method 1: add a variable to the/etc/profile file [effective for all users (permanent )]
Use VI to add a variable to the/etc/profile File. this variable will be valid for all users in Linux and will be "permanent ".

vi /etc/profile
Add the following two lines of code to the end of the file:
PATH=/opt/mono-20150520032320/bin:$PATH export PATH

The modification takes effect. run the following code (otherwise restart reboot)

source /etc/profile

Method 2: Create a Mono configuration under the/etc/profile. d/directory.

cd /etc/profile.d/

Create a new mono. sh

vi mono.sh

Write the following content into this file:

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

The "mono-20150520032320" in the path is shown above. if you need to configure an updated version, you can configure the path.

The modification takes effect. you need to execute the following code:

source mono.sh

Now you can directly execute the Mono command.
