CentOS7 install RabbitMQ test

Use yum install erlangthe command to install erlang, and then download RabbitMQ rabbitmq-server-3.7.4-1.el7.noarch.rpmWhen executing the rpm -ivh rabbitmq-server-3.7.4-1.el7.noarch.rpmcommand, an error is reported

warning: rabbitmq-server-3.7.4-1.el7.noarch.rpm: Header V4 RSA/SHA1 Signature, key ID 6026dfca: NOKEY
error: Failed dependencies:
    erlang >= 19.3 is needed by rabbitmq-server-3.7.4-1.el7.noarch
    socat is needed by rabbitmq-server-3.7.4-1.el7.noarch

There are two problems here: Problem 1, erlang >= 19.3 is needed by rabbitmq-server-3.7.4-1.el7.noarchProblem 2, and socat is needed by rabbitmq-server-3.7.4-1.el7.noarchthen around these two problems.

Prepare

RabbitMQ: rpm -ivh rabbitmq-server-3.7.4-1.el7.noarch.rpm Download please click here ; erlang: Download please click here

Question two,`socat is needed by rabbitmq-server-3.7.4-1.el7.noarch`

Solution: use the command yum -y install socatto install, I see that some bloggers will encounter another problem at this step 会报错没有socat包或是找不到socat包，解决方法安装centos的epel的扩展源, the solution to this problem: yum -y install epel-releaseexecute this command and then execute the previous socat installation command

Question one,`erlang >= 19.3 is needed by rabbitmq-server-3.7.4-1.el7.noarch`

Since we yum install erlanginstalled erlang using the command, its version is not supported, rabbitmq-server-3.7.4-1.el7.noarchso we reinstall the 19.3 version given by the prompt.

Preparing to install Erlang

First we need to prepare the installation environment

Installation of dependent environment - if you need to compile and install the erlang language environment, you need to install C++ to compile. yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel unixODBC unixODBC-devel httpd python-simplejson I re-install these things with the yum command and then compile, and then compile without error. Execute the install command again.

Get Erlang (the 19.3 version is indicated above, but I can't install it, so I try to download a version that is not the latest)

[root@izbp1e0h5tks006vnlaro4z tool]# wget http://erlang.org/download/otp_src_20.2.tar.gz

Unzip the erlang installation package, there will be a lot of things

# tar -xzvf otp_src_20.2.tar.gz

Then we enter the unzipped directory

# cd otp_src_20.2

Compile and install erlang language environment prefix=/usr/local/erlang is the installation directory

./configure  --prefix=/usr/local/erlang --enable-smp-support  --enable-threads  --enable-sctp --enable-kernel-poll --enable-hipe  --with-ssl --without-javac

If the installation environment is not ready, an error will be reported when compiling here

configure: error: No curses library functions found
configure: error: /bin/sh '/usr/local/tool/otp_src_19.3/erts/configure' failed for erts

Start installing and compiling:

make && make install

Configure erlang environment variables:

vim /etc/profile

export PATH=$PATH:/usr/local/erlang/bin
//执行下面命令修改配置文件立即生效
source /etc/profil

Verify that the installation was successful:

//注释：输入erl Erlang/OTP 17 [erts-6.2] [source] [smp:2:2] [async-threads:10] [kernel-poll:false]，会输出版本号信息

# erl Erlang/OTP 17 [erts-6.2] [source] [smp:2:2] [async-threads:10] [kernel-poll:false]

Erlang R16B03-1 (erts-5.10.4) [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V5.10.4  (abort with ^G)

Start installing the rabbitmq rpm package

You need to go back to the rabbitmq installation package directory

Execute the rpm install command

# rpm -ivh rabbitmq-server-3.7.4-1.el7.noarch.rpm

Installed the things prepared earlier but still reported an error

[root@ tool]#  rpm -ivh rabbitmq-server-3.7.4-1.el7.noarch.rpm 
warning: rabbitmq-server-3.7.4-1.el7.noarch.rpm: Header V4 RSA/SHA1 Signature, key ID 6026dfca: NOKEY
error: Failed dependencies:
	erlang >= 19.3 is needed by rabbitmq-server-3.7.4-1.el7.noarch

This method will prompt that the version needs to be greater than R13, and adding -nodeps is ok

The above error is because the configuration file I modified does not take effect immediately, PS:/etc/profile It needs to be added in the configuration file export PATH=$PATH:/usr/rabbitmq/sbin, save it and make the file take effect: source /erc/profile; reinstall it again
