Installation and configuration of RABBITMQ under Linux

a Erlang installation

1.RabbitMQ is based on Erlang, so you must first configure the Erlang environment.

Download the latest Erlang installation package from Erlang's official website http://www.erlang.org/download.html, the version of Linux and MacOSX download is http://www.erlang.org/download.html

2. Then unzip the downloaded GZ package TAR-ZXVF *.tar.gz

3.cd into the extracted folder

4. Execute./configure--prefix=/opt/erlang will start compiling the installation will be compiled to/opt/erlang if you do not error, execute make and make install

5. If you have an error:

6.[[email protected] ~]# Yum install gcc

Continue to Error

Redhat The default comes with the Yum source need to register, to update, error:
This system isn't registered to Red hatsubscription Management. You can use the Subscription-manager to register.
Can be replaced with centos corresponding source. The operation is as follows:

1. Check if the Yum package is installed. To see if Rhel is installed with Yum, and if so, what Yum packages are available:
Rpm-qa |grep Yum

2 Delete Redhat's own Yum pack
Rpm-qa|grep Yum|xargs rpm-e--nodeps (without checking dependencies, delete rpm packages directly)
Rpm-qa |grep Yum (query confirmation)
[Email protected] ~]#

3. Download the new Yum package. Yum Package with Centos6.5
1) View the version number and system category:
Cat/etc/redhat-release
Arch

2) Follow the previous step to find the corresponding Yum package and download it. My server corresponds to the following:
wget http://mirrors.163.com/centos/6/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

wget http://mirrors.163.com/centos/6/yum-3.2.29-40.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

3) Execution:
rpm-ivhyum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-3.2.29-40.el6.centos.noarch.rpmyum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
If this step is an error, the outsole is as follows:
Libc.so.6 is needed by yum-metadata-parser-1.1.2-16.el6.i686
Libc.so.6 (glibc_2.0) is needed by yum-metadata-parser-1.1.2-16.el6.i686
Libc.so.6 (glibc_2.1.3) is needed by yum-metadata-parser-1.1.2-16.el6.i686
Libglib-2.0.so.0 is needed by yum-metadata-parser-1.1.2-16.el6.i686
Libpthread.so.0 is needed by yum-metadata-parser-1.1.2-16.el6.i686
libpython2.6.so.1.0 is needed by yum-metadata-parser-1.1.2-16.el6.i686
Libsqlite3.so.0 is needed by yum-metadata-parser-1.1.2-16.el6.i686
Libxml2.so.2 is needed by yum-metadata-parser-1.1.2-16.el6.i686
Libxml2.so.2 (libxml2_2.4.30) is needed byyum-metadata-parser-1.1.2-16.el6.i686
The Yum package downloaded and installed does not match the system version and requires a re-download of the installation. In addition, 163 mirror sites are merged into the 6 directory for 6.0~6.5 resources.

4) Replace the Yum source, delete or back up the original source under another:
cd/etc/yum.repos.d/
wgetHttp://mirrors.163.com/.help/CentOS6-Base-163.repo
Vicentos6-base-163.repo
Edit the file and replace all the $releasever in the file with the version number: 6 (note, not 6.5!) ) Last Save!

4. Clear the original cache and rebuild the cache:
Clean all
Yum Makecache

5. Update the system:
Yum Update

6. [Email protected]~]# yum Install gcc

at this point, if no error description GCC Installation Successful

start the installation again Erlang

Reference http://blog.csdn.net/chszs/article/details/28638305

Erlang is now part of the Fedora and Debian/ubuntu software repositories.

The most current version of Erlang is OTP 18.2. Erlang is a programming language used to build a programming language for large-scale, highly scalable, high-availability soft real-time systems. It has been used in telecommunications, finance, e-commerce, VoIP, and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution, and fault tolerance.

OTP is a collection of Erlang libraries and design principles that provide middleware for developing various systems. It contains its own distributed database, interfaces for other programming languages, Debug and release processing tools, and so on.

Beam is the virtual machine required for Erlang code execution. The Erlang code is compiled with a. beam extension. ERTs is an Erlang runtime system that includes components such as beam, kernels, and standard libraries.

The official recommendation is to install Erlang from the source code, so the following begins installing OTP 18.2 from the source.

Download OTP 18.2 Source: http://www.

There are several ways to exit the Erlang shell

Command mode 1: Execute Init:stop ().
Command mode 2: Execute Halt ().
Shortcut key mode 1:control+c then select a
Shortcut key mode 2:control+g then press Q

1. After the compilation is complete, enter/opt/erlang and the ERL test Erlang is installed successfully.
2. Modify the/etc/profile file to add the following environment variables:
3. #set Erlang Environment
4. Export path= $PATH:/opt/erlang/bin
5. Source profile makes the file effective
6. Ken will be unable to find the package, just go directly to yum install.

Modify the/etc/profile file to add the following environment variable

Erl_home=/opt/erlang

Path= $ERL _home/bin: $PATH

Exporterl_home PATH

"Installation Summary"

To install Erlang from source code, there are two libraries or tools that are required:

One is the full GCC compiler environment
Second, the Ncurses Development library

There are also libraries or tools that, if they are not present, will have a warning message when compiling the configuration, and may not be configured. These libraries are:

1) OpenSSL Development Library

2) ODBC Development Library

3) Java compiler

two. Installing RabbitMQ

1. RPM--IMPORTHTTPS://WWW.RABBITMQ.COM/RABBITMQ-SIGNING-KEY-PUBLIC.ASC

Yum installrabbitmq-server-3.6.0-1.noarch.rpm

1. Wget-c http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.0/rabbitmq-server-3.6.0-1.noarch.rpm

Yum installrabbitmq-server-3.6.0-1.noarch.rpm

The above two statements can be successfully installed on any one of the following lines:

But I encountered a problem in installing Rabbitmq-server:

Error:package:rabbitmq-server-3.6.0-1.noarch (/rabbitmq-server-3.6.0-1.noarch)
Requires:erlang >= r16b-3
You could try using--skip-broken to work around the problem
You could try Running:rpm-va--nofiles--nodigest

This is due to the version problem of Erlang, in fact there is no impact, you can use Rpm-ivh--nodeps rabbitmq-server-3.6.0-1.noarch.rpm installation.

If the installation is not successful: use the following trick

three RABBITMQ Installation Configuration

1. There are many versions of RABBITMQ installed, and we use the generic UNIX version.
2. CD/
3. wget http://www.rabbitmq.com/releases/rabbitmq-server/v2.7.1/rabbitmq-server-generic-unix-2.7.1.tar.gz Download RABBITMQ
4. Tar zxvf rabbitmq-server-generic-unix-2.7.1.tar.gz-c/opt unzip to the specified folder
5. Cd/opt, establishing a soft link ln-s rabbitmq-server-generic-unix rabbitmq
6. CD rabbitmq/sbin,./rabbitmq-server-detached to enable background startup
7. modifying/etc/profile, adding environment variables
8. #set RABBITMQ Environment
9. Export path= $PATH:/opt/rabbitmq/sbin
10. Source profile makes the file effective
11. Cd/opt/rabbitmq/sbin,./rabbitmqctl Stop shutdown RABBITMQ
12. This completes the installation
13. Enable Admin mode (manage MQ with Web page) cd/opt/rabbitmq/sbin/
14. Execution./rabbitmq-pluginenable rabbitmq-management
15. Then visit http://localhost:55672

a . if it's installed as a service, start with this.

[Email protected] ~]# service Rabbitmq-server restart

Warning:ignoring/etc/rabbitmq/rabbitmq.conf--location has moved to/etc/rabbitmq/rabbitmq-env.conf
