CentOS from scratch to build wxWidgets, erlang, RabbitMQ (single version) (absolute scratch to build ultra-detailed)

Foreword

This article is mainly aboutRabbitMQinstallation

1, the installation environment wxWidgets

• Since rabbitmq is written in erlang, before installing rabbitmq, you need to install erlang, you need to install before installing wxWidgets erlang, you need to install before installing wxWidgetsgtk2-develversusbinutils-devel, Ado quickly get started .
  • First, let's update the system

    yum update
    

  • Install wxWidgets related dependency, do not install this will be reported the following error

    yum -y install gtk2-devel binutils-devel
    

    Error contents:

    checking for GTK+ version... 
    checking for pkg-config... /usr/bin/pkg-config
    checking for GTK+ - version >= 2.6.0... no
    *** Could not run GTK+ test program, checking why...
    *** The test program failed to compile or link. See the file config.log for the
    *** exact error that occurred. This usually means GTK+ is incorrectly installed.
    checking for pkg-config... (cached) /usr/bin/pkg-config
    checking for GTK+ - version >= 3.0.0... no
    *** Could not run GTK+ test program, checking why...
    *** The test program failed to compile or link. See the file config.log for the
    *** exact error that occured. This usually means GTK+ is incorrectly installed.
    checking for gtk-config... no
    checking for GTK - version >= 1.2.7... no
    *** The gtk-config script installed by GTK could not be found
    *** If GTK was installed in PREFIX, make sure PREFIX/bin is in
    *** your path, or set the GTK_CONFIG environment variable to the
    *** full path to gtk-config.
    checking for gtk-config... (cached) no
    checking for GTK - version >= 1.2.3... no
    *** The gtk-config script installed by GTK could not be found
    *** If GTK was installed in PREFIX, make sure PREFIX/bin is in
    *** your path, or set the GTK_CONFIG environment variable to the
    *** full path to gtk-config.
    configure: error: 
    The development files for GTK+ were not found. For GTK+ 2, please
    ensure that pkg-config is in the path and that gtk+-2.0.pc is
    installed. For GTK+ 1.2 please check that gtk-config is in the path,
    and that the version is 1.2.3 or above. Also check that the
    libraries returned by 'pkg-config gtk+-2.0 --libs' or 'gtk-config
    --libs' are in the LD_LIBRARY_PATH or equivalent.
    

  • Since erlang rely wxWidgets, we download the installation package download wxWidgets, wxWidgets version is 2.8.4 or later, here we download the latest version 3.1.3 version, intended to build use Thunder download
    wxWidgets official website Download

    wget https://github.com/wxWidgets/wxWidgets/releases/download/v3.1.3/wxWidgets-3.1.3.tar.bz2
    

  • Create a folder wxWidgets installation path

    mkdir -p /usr/local/wxWidgets
    

  • Decompression wxWidgets

    tar -xvf wxWidgets-3.1.3.tar.bz2
    

  • Enter wxWidgets directory

    cd wxWidgets-3.1.3/
    

  • Compile wxWidgets

    ./configure --with-regex=builtin --with-gtk --enable-unicode --disable-shared --prefix=/usr/local/wxWidgets
    

  • Start the installation wxWidgets,Wait for the process is very longI once thought it was abnormal message is displayed (in fact, no anomalies appear, just compile files), anywayWe must wait patiently compiled file, Stop in the middle of an exception, appear in the following figure, says the installation was successful,

    make && make install
    

  
  • Ready to set its dynamic library

    cd /etc/ld.so.conf.d/
    

  • Create a file

    touch wxWidgets.conf
    

  • open a file

    vim wxWidgets.conf
    

  • Add the following

    /usr/local/lib
    

  • Reload the dynamic library configuration

    ldconfig
    

  • WxWidgets configuration environment variable =

    vim /etc/profile
    

  • The following profile is stored to a file, save and exit

    export WXPATH=/usr/local/wxWidgets/
    export PATH=$WXPATH/bin:$PATH
    

  • And refresh the environment variables to take effect

    source /etc/profile
    

  • View wx version number

    wx-config --version
    

2, install java development environment

• Check our JDK

  java version
  

• If not, install the following command

  Browse JDK version
  yum -y list java *
  choose your own version of the installation, I chose 1.8, 1.9 and 1.9 can not select or later, because Elasticsearch does not support
  yum install java-1.8.0-openjdk- devel.x86_64
  installed by yum the location jdk / usr / lib / jvm

• Began to set environment variables

  vim / etc / profile
  then the lowermost portion of the document enter the following code, save and exit

  export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64
  export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
  export PATH=$PATH:$JAVA_HOME/bin
  

• We completed the installation of the JDK

3, start the installation related dependencies erlang

• At this moment, I seem to relieve a sigh of relief, because when you see here, I haveInstallation failed six timesThe
  • Start the installation related dependencies erlang

    yum install -y epel-release
    

    yum install -y make gcc gcc-c++ m4 openssl openssl-devel ncurses-devel unixODBC unixODBC-devel java java-devel
    

  • Since the Rabbit-3.8.2 version only supports erlang version 21.3 to 22.x [], and yum source only version 3.3, so we downloaded erlang / otp-22.2 compression package, and then point out, hard to find erlang Download I look for an hour, there will be accompanied by erlang Download

    wget http://erlang.org/download/otp_src_22.2.tar.gz
    

    
    Download erlang version of the list (old slow load times, and if it is not loaded, and the page stops loading small partner, please be patient, refresh it again, if that does not work, the more refreshed several times.)
    
  • To decompress compressed package erlang to opt directory

    tar -xvf otp_src_22.2.tar.gz -C /opt
    

  • Create a directory erlang

    mkdir -p /usr/local/erlang
    

  • Into the extracted directory

    cd /opt/otp_src_22.2/
    

  • Began to compile erlang ( do not enter the unzipped it does not matter ), there will be after the completion of the following figure. He warned about the matter.

    /opt/otp_src_22.2/configure --prefix=/usr/local/erlang
    

    
  • Install erlang, the installation process is relatively long, please be patient, after the successful installation as shown below

    make && make install
    

    
  • Modify environment variables

    vim /etc/profile
    

  • The following profile is stored to a file, save and exit

    export ERLPATH=/usr/local/erlang
    export PATH=$ERLPATH/bin:$PATH
    

  • And refresh the environment variables to take effect

    source /etc/profile
    

  • Erlang verify whether the installation is successful, the content in the following figure appears to indicate a successful build

    erl
    

* Until now environment variables written presentation

4、获最新版本的RabbitMQ安装包

• 由于使用yum命令获取RabbitMQ版本列表，只能获取到3.3.5版本，所以这里我们采用压缩包的形式安装最新版-3.8.2版本。
  • 首先，我们将当前位置移动至opt目录下

    cd /opt
    

  • 开始下载RabbitMQ-3.8.2压缩包

    wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.2/rabbitmq-server-generic-unix-3.8.2.tar.xz
    

  • 不好意思啊，我这边github上下载太慢了，我直接用迅雷下载了，地址给你们附上

    https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.2/rabbitmq-server-generic-unix-3.8.2.tar.xz
    

    RabbitMQ的GitHub相关页面

5、开始搭建RabbitMQ环境

• 这里没有标题
  • 对压缩包进行解压

    tar -xvf rabbitmq-server-generic-unix-3.8.2.tar.xz
    

  • 此时我们RabbitMQ的安装位置在【/opt/rabbitmq_server-3.8.2】，现在我们准备添加环境变量

    vim /etc/profile
    

  • 将以下内容存储至profile文件中，保存并退出，这个环境变量要是不想设置也每关系，直接去文件里运行文件即可

    PATH=$PATH:/opt/rabbitmq_server-3.8.2/sbin
    

  • 使环境变量刷新并生效

    source /etc/profile
    

  • 添加web管理插件，添加成功后如下图所示

    rabbitmq-plugins enable rabbitmq_management
    

    
  • 在/opt/rabbitmq_server-3.8.2/etc/rabbitmq创建配置文件（其实也不用创建，设置为默认即可，因为我们现在是单机环境搭建），rabbitMq默认是不自带配置文件的，可以去github上复制一份
  • RabbitMQ配置文件下载

    vim /opt/rabbitmq_server-3.8.2/etc/rabbitmq/rabbitmq.conf
    

  • 输入你需要修改的内容，保存并退出

6、 开启端口或关闭防火墙

• 临时关闭防火墙命令

  systemctl stop firewalld
  

---

• 开启相关端口（推荐）

  firewall-cmd --zone=public --add-port=5672/tcp --permanent
  firewall-cmd --zone=public --add-port=15672/tcp --permanent
  

• 更新防火墙规则

  firewall-cmd --complete-reload
  

• 查看当前所开放的端口

  firewall-cmd --zone=public --list-ports
  					
  

7、启动RibbitMQ

• 后台启动RibbitMQ

  rabbitmq-server start -detached
  

• 其他命令

  启动
  rabbitmq-server stop
  状态
  rabbitmq-server status

8、进入RibbitMQ管理界面

127.0.0.1:15672
