centos7 获取软件的所有依赖包

• 一、环境介绍
• 二、安装jdk
• 三、安装erlang
• 四、安装依赖
• 五、安装RabbitMQ
• 六、访问
• 七、使用
• 八、问题集锦

一、环境介绍

操作系统：centos7
RabbitMq版本：3.8.4

关闭firewalld
禁用 SELinux ，修改 /etc/selinux/config
SELINUX=disabled
rabbitmq-server启动过程需要连接主机名，配置host解析，修改/etc/hosts，增加映射

二、安装jdk

先查看系统是否已有自带的jdk

rpm -qa |grep java
rpm -qa |grep jdk
rpm -qa |grep gcj

[root@localhost home]# rpm -qa |grep java
java-1.7.0-openjdk-headless-1.7.0.191-2.6.15.5.el7.x86_64
java-1.8.0-openjdk-headless-1.8.0.181-7.b13.el7.x86_64
python-javapackages-3.4.1-11.el7.noarch
java-1.8.0-openjdk-1.8.0.181-7.b13.el7.x86_64
tzdata-java-2018e-3.el7.noarch
javapackages-tools-3.4.1-11.el7.noarch
java-1.7.0-openjdk-1.7.0.191-2.6.15.5.el7.x86_64

如果没有输出信息，则说明系统没有安装。如果有输出信息，则执行下面的命令卸载

rpm -qa | grep java | xargs rpm -e --nodeps
[root@localhost home]# rpm -qa | grep java | xargs rpm -e --nodeps
[root@localhost home]# rpm -qa |grep java
[root@localhost home]#

下载jdk8安装文件
https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
拷贝到home目录

[root@localhost home]# cp /mnt/hgfs/winfolder/jdk-8u231-linux-x64.tar.gz /home

解压

[root@localhost home]# tar -zxf jdk-8u231-linux-x64.tar.gz

配置java环境变量

[root@localhost home]# vi /etc/profile

增加如下内容

JAVA_HOME=/home/jdk1.8.0_231
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME CLASSPATH

使配置立即生效

[root@localhost home]# source /etc/profile

查看jdk安装情况

三、安装erlang

RabbitMq的运行依赖erlang，需要先安装erlang
RabbitMq与erlang版本对应关系如下
https://www.rabbitmq.com/which-erlang.html
下载erlang
https://www.erlang.org/downloads/22.3

解压

[root@localhost]#tar -zxvf otp_src_22.3.tar.gz

编译安装erlang语言环境，设置编译目录为 /opt/erlang

[root@localhost otp_src_22.3]# ./configure --prefix=/opt/erlang --enable-hipe --enable-threads --enable-smp-support --enable-kernel-poll

安装

[root@localhost otp_src_22.3]# make
[root@localhost otp_src_22.3]# make install

配置环境变量

[root@localhost otp_src_22.3]# vi /etc/profile

增加如下内容

ER_HOME=/opt/erlang
PATH=$PATH:$ER_HOME/bin
export PATH ER_HOME

使环境变量生效

[root@localhost otp_src_22.3]# source /etc/profile

验证

　　在任意目录下输入 erl 命令，出现如下图，则 erlang 安装成功

四、安装依赖

[root@localhost otp_src_22.3]# yum install perl
[root@localhost otp_src_22.3]# yum install unixODBC.x86_64 unixODBC-devel.x86_64
[root@localhost otp_src_22.3]# yum install gtk3-devel.x86_64
[root@localhost otp_src_22.3]# yum install -y make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel unixODBC unixODBC-devel httpd python-simplejson 
[root@localhost otp_src_22.3]# yum -y install glibc-devel make xmlto wget
[root@localhost otp_src_22.3]# yum install -y epel-release socat
[root@localhost otp_src_22.3]# yum install mesa *
[root@localhost otp_src_22.3]# yum install freeglut*

安装wxWidgets

[root@localhost]# wget https://netix.dl.sourceforge.net/project/wxwindows/3.0.1/wxWidgets-3.0.1.tar.bz2
[root@localhost]# bzip2 -dkv wxWidgets-3.0.1.tar.bz2
[root@localhost]# tar -xvf wxWidgets-3.0.1.tar
[root@localhost]# cd wxWidgets-3.0.1/
[root@localhost]# ./configure --with-opengl --enable-debug --enable-unicode
[root@localhost]# make && make install

五、安装RabbitMQ

下载安装包
https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.4/rabbitmq-server-3.8.4-1.el7.noarch.rpm

导入秘钥

[root@localhost tools]# rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc

安装

[root@localhost tools]# rpm -ivh --nodeps rabbitmq-server-3.8.4-1.el7.noarch.rpm

查看状态

[root@localhost tools]# systemctl status rabbitmq-server

启用插件

[root@localhost tools]# rabbitmq-plugins enable rabbitmq_management

查看插件列表

[root@localhost tools]# rabbitmq-plugins list

六、访问

浏览器访问http://ip:15672/

默认用户guest/guest 只允许localhost登录

添加用户，后面两个参数分别是用户名和密码

[root@localhos]# rabbitmqctl add_user test 1234

添加权限

[root@localhos]# rabbitmqctl set_permissions -p / test ".*" ".*" ".*"

修改用户角色

[root@localhos]# rabbitmqctl set_user_tags test administrator

查看用户

[root@localhos]#  rabbitmqctl list_users
Listing users ...
user    tags
guest   [administrator]
test    [administrator]

用新用户登录

其它操作

rabbitmqctl delete_user Username #删除一个用户

rabbitmqctl change_password Username Newpassword #修改用户密码

rabbitmqctl list_users #查看当前用户列表

七、使用

新增一个 virtual hos，区分业务

新增一个exchange 交换空间

新增 queue 队列

绑定exchange 和 queue

解决

[root@localhos]# vi /usr/lib/rabbitmq/bin/rabbitmq-server

增加如下内容

ER_HOME=/opt/erlang
PATH=$PATH:$ER_HOME/bin
export PATH ER_HOME

启动rabbitmq

[root@localhos]# systemctl restart rabbitmq-server
[root@localhos]# systemctl status rabbitmq-server
