RabbitMQ环境搭建及遇到问题解决办法

RabbitMQ环境搭建

1、 安装依赖

1、RabbitMQ的安装需要首先安装Erlang，因为它是基于Erlang的VM运行的；

2、RabbitMQ需要的依赖：socat、logrotate、logrotate，后两个操作系统中已经存了，只需要安装socat即可；

3、安装socat：

[root@10 /]# yum install socat -y
.......
总下载量：290 k
安装大小：1.1 M
Downloading packages:
socat-1.7.3.2-2.el7.x86_64.rpm                                      | 290 kB  00:00:00   
Running transaction check
Running transaction test
Transaction test succeeded
Running transaction
  正在安装    : socat-1.7.3.2-2.el7.x86_64                                           1/1 
  验证中      : socat-1.7.3.2-2.el7.x86_64                                           1/1 

已安装:
  socat.x86_64 0:1.7.3.2-2.el7                                                           
完毕！

2、 安装Erlang

1、下载地址：https://github.com/rabbitmq/erlang-rpm/releases/download/v23.0.2/erlang-23.0.2-1.el7.x86_64.rpm

2、安装包上传linux服务器；

3、安装软件包：

[root@10 software]# pwd
/home/laosan/software
[root@10 software]# yum -y install erlang-23.0.2-1.el7.x86_64.rpm 

3、 安装RabbitMQ

1、下载地址：https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.5/rabbitmq-server-3.8.5-1.el7.noarch.rpm

2、安装包上传linux服务器；

3、安装软件包：

[root@10 software]# pwd
/home/laosan/software
[root@10 software]# yum -y install rabbitmq-server-3.8.5-1.el7.noarch.rpm 
已加载插件：fastestmirror, langpacks
正在检查 rabbitmq-server-3.8.5-1.el7.noarch.rpm: rabbitmq-server-3.8.5-1.el7.noarch
rabbitmq-server-3.8.5-1.el7.noarch.rpm 将被安装

4、查看是否安装成功

1、开机启动项：

[root@10 software]# systemctl list-unit-files | grep rabbitmq-server
rabbitmq-server.service                     disabled

2、disabled代表不会随着开机启动；

3、查看rabbitmq安装目录：

[root@10 rabbitmq_server-3.8.5]# pwd
/usr/lib/rabbitmq/lib/rabbitmq_server-3.8.5
[root@10 rabbitmq_server-3.8.5]# ll
总用量 16
drwxr-xr-x. 2 root root 4096 8月   5 22:01 escript
drwxr-xr-x. 2 root root 4096 8月   5 22:01 plugins
drwxr-xr-x. 2 root root 4096 8月   5 22:01 sbin

4、plugins——自带插件；sbin——可执行文件；

5、启用UI管理工具插件

1、执行命令：

[root@10 sbin]# pwd
/usr/lib/rabbitmq/lib/rabbitmq_server-3.8.5/sbin
[root@10 sbin]# rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node rabbit@10:
rabbitmq_management
The following plugins have been configured:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch
Applying plugin configuration to rabbit@10...
The following plugins have been enabled:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch

set 3 plugins.
Offline change; changes will take effect at broker restart.

2、查看插件列表；

[root@10 sbin]# rabbitmq-plugins list
Listing plugins with pattern ".*" ...
 Configured: E = explicitly enabled; e = implicitly enabled
 | Status: [failed to contact rabbit@10 - status not shown]
 |/
[  ] rabbitmq_amqp1_0                  3.8.5
[  ] rabbitmq_jms_topic_exchange       3.8.5
[E ] rabbitmq_management               3.8.5
[e ] rabbitmq_management_agent         3.8.5
[  ] rabbitmq_mqtt                     3.8.5
[  ] rabbitmq_trust_store              3.8.5
[e ] rabbitmq_web_dispatch             3.8.5
[  ] rabbitmq_web_stomp                3.8.5
[  ] rabbitmq_web_stomp_examples       3.8.5

3、插件前面大写E代表手动启用该插件，小写字母e代表自动启动该插件；

5、启动rabbitmq

1、前台模式执行启动命令（后台启动需要在命令后面加上-detached）：

[root@10 sbin]# rabbitmq-server 
  ##  ##      RabbitMQ 3.8.5
  ##  ##

  Logs: /var/log/rabbitmq/[email protected]
        /var/log/rabbitmq/rabbit@localhost_upgrade.log
  Config file(s): (none)
  Starting broker... completed with 3 plugins.

2、已经启动且同时启用三个插件；

5、浏览器登陆rabbitmq

1、浏览器输入地址登陆：http://192.168.0.104:15672/

2、输入用户名和密码分别为系统自带的guest；

3、提示该用户只能本机登陆；

6、配置rabbitmq用户

1、再开一个窗口查看当前用户有哪些：

[root@10 ~]# rabbitmqctl list_users
Listing users ...
user	tags
guest	[administrator]

2、添加用户laosan和密码：

[root@10 ~]# rabbitmqctl add_user laosan 123456
Adding user "laosan" ...
[root@10 ~]# rabbitmqctl list_users
Listing users ...
user	tags
guest	[administrator]
laosan	[]

3、给用户laosan设置标签

[root@10 ~]# rabbitmqctl set_user_tags laosan administrator
Setting tags for user "laosan" to [administrator] ...

4、给用户laosan设置权限

[root@10 ~]# rabbitmqctl set_permissions laosan -p / ".*" ".*" ".*"
Setting permissions for user "laosan" in vhost "/" ...

5、再次登录页面，访问成功管理页面

遇到问题及解决

问题1：升级openssl

[root@10 software]# rpm -ivh erlang-23.0.2-1.el7.x86_64.rpm rabbitmq-server-3.8.5-1.el7.noarch.rpm 
警告：erlang-23.0.2-1.el7.x86_64.rpm: 头V4 RSA/SHA1 Signature, 密钥 ID 6026dfca: NOKEY
错误：依赖检测失败：
	libcrypto.so.10(OPENSSL_1.0.2)(64bit) 被 erlang-23.0.2-1.el7.x86_64 需要
	libsystemd.so.0()(64bit) 被 erlang-23.0.2-1.el7.x86_64 需要
	libsystemd.so.0(LIBSYSTEMD_209)(64bit) 被 erlang-23.0.2-1.el7.x86_64 需要

解决：

1、下载openssl安装包：http://rpmfind.net/linux/rpm2html/search.php?query=libcrypto.so.10%28OPENSSL_1.0.2%29%2864bit%29&submit=Search+…&system=&arch=

2、升级openssl：

[root@10 software]# rpm -ivh openssl-libs-1.0.2k-19.el7.x86_64.rpm
