CentOS 7 安装RabbitMQ 3.3及单机多实例实现、经常使用命令

1、安装erlang 语言环境

安装依赖文件

#yum -y installncurses-devel

yum -y install gcc gcc-c++

yum -y install zlib zlib-devel xmlto

安装python  ,能够执行python –V查询是否安装，通常系统自带已安装。

 

进入http://www.erlang.org/download.html选择源文件下载

wgethttp://www.erlang.org/download/ otp_src_17.1.tar.gz

tar zxvf  otp_src_17.1.tar.gz

cd otp_src_17.1

    阅读HOTO/INSTALL.md文件

#./configure

   #make && make install

安装完成之后，执行erl看是否能打开eshell，用’halt().’退出，注意后面的点号，那是erlang的结束符。

[root@localhostsrc]# erl
Erlang/OTP 17 [erts-6.1] [source] [64-bit] [async-threads:10] [hipe][kernel-poll:false]

EshellV6.1  (abort with ^G)
2> 9+3.
12
3> halt().

2、安装RabbitMQ

 

进入http://www.rabbitmq.com/download.html选择最新的源码包

#wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.3.4/rabbitmq-server-3.3.4.tar.gz

#tar zxvfrabbitmq-server-3.3.4.tar.gz

mkdir /usr/rabbitmq

#cdrabbitmq-server-3.3.4

#makeTARGET_DIR=/usr/rabbitmq SBIN_DIR=/usr/rabbitmq/sbin MAN_DIR=/usr/rabbitmq/man DOC_INSTALL_DIR=/usr/rabbitmq/doc

#makeTARGET_DIR=/usr/rabbitmq SBIN_DIR=/usr/rabbitmq/sbin MAN_DIR=/usr/rabbitmq/manDOC_INSTALL_DIR=/usr/rabbitmq/doc  install

3、启动rabbitmq-server

运行rabbitmq:

#/usr/rabbitmq/sbin/rabbitmq-server  start&

(或者#/usr/rabbitmq/sbin/rabbitmq-server -detached)

须要在/etc/hosts 中添加

127.0.0.1 localhost主机名

 

 

四、安装web插件管理界面—必须安装web插件，不然没法启用15672端口和进行web页面登陆

#cd /usr/rabbitmq/sbin 

#mkdir /etc/rabbitmq/  --默认插件是安装到此目录，因此必须建立 

#./rabbitmq-plugins enablerabbitmq_management 

五、好了，到这里rabbitmq已经配置好了，能够启动了：

#./rabbitmq-server start& 

我运行的时候报错了，ERROR: epmd errorfor host "springzoo": timeout (timed out)

更改下/etc/hosts:  

127.0.0.1   localhost springzoo

::1         localhost springzoo

# ps aux | grep rabbitmq //查看端口，默认就是5672

netstat -tnlp | grep 5672

tcp        0      00.0.0.0:15672               0.0.0.0:*                  LISTEN     30435/beam.smp      

tcp        0      00.0.0.0:55672               0.0.0.0:*                  LISTEN     30435/beam.smp      

tcp        0      0:::5672                    :::*                       LISTEN      30435/beam.smp

若是看到下面的信息就代表已经启动成功了： 

                 

         

运行以下的命令，增长用户admin，密码admin

[root@localhost sbin]# ./rabbitmqctl add_user admin admin
Creating user "admin" ...
...done.
[root@localhost sbin]# ./rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...
...done.
[root@localhost sbin]# ./rabbitmqctl list_users
Listing users ...
admin   [administrator]
guest   [administrator]
...done.

 

 

最后关闭防火墙咱们就能够在浏览器上输入http://127.0.0.1:15672/登陆管理界面了(因为端口号过大，若是没法经过防火墙，那必须关闭防火墙)

使用登陆的名户名和密码默认都算admin，登陆后的页面以下：

查看rabbitmq状态:

#/usr/rabbitmq/sbin/rabbitmqctl status

关闭rabbitmq:

#/usr/rabbitmq/sbin/rabbitmqctl stop

6、查看RabbitMQ服务启动的状态，并开启RabbitMQ的相应管理插件

[root@localhostsbin]# ./rabbitmqctl status

[root@localhost sbin]#

配置开机启动

vi /etc/rc.d/rc.local

添加

/usr/rabbitmq/sbin/rabbitmq-server  start &

 

 

 

在另外一台服务器上安装rabbit时，遇到问题

/bin/sh: nc: 未找到命令

/bin/sh: zip: 未找到命令

这会致使有部分文件没法编译生成，因此必须先安装这两个命令

yum -y install zip nc unzip

 

遇到的问题

1.解压rabbit安装包后，须要新建一个目录，与make命令中制定的文件目录一致，可是不要直接指定为rabbit解压目录，不然会出现$home$/sbin目录为空的状况。

2.服务器重启后启动common等须要链接到rabbitmq的服务，发现启动报错，没法启动，

3.执行还原命令rabbitmqctlreset时报错：

Error:mnesia_unexpectedly_running

 

须要执行的是:

 

[root@HK-210209127027 ~]# rabbitmqctlstop_app

[root@HK-210209127027 ~]# rabbitmqctlreset

[root@HK-210209127027 ~]# rabbitmqctlcluster root@HK-210209127027

 

 

 

经常使用命令：

查看全部队列信息

# rabbitmqctllist_queues

关闭应用

# rabbitmqctlstop_app

启动应用，和上述关闭命令配合使用，达到清空队列的目的

# rabbitmqctlstart_app

清除全部队列

# rabbitmqctl reset

更多用法及参数，能够执行以下命令查看

# rabbitmqctl

 

（1）首先关闭rabbitmq: rabbitmqctl stop_app

（2）还原： rabbitmqctl reset

（3）启动： rabbitmqctl start_app

（4）添加用户： rabbitmqctl add_user root root

（5）设置权限：rabbitmqctl set_permissions -p / root".*" ".*" ".*"

（6）查看用户： rabbitmqctl list_users

 

 

在单机上实现rabbitmq多实例操做：

须要修改的配置文件为：

#vim /etc/rabbitmq/rabbitmq.config

[

{rabbit,

  [

  {tcp_listeners, [5672]},

  {tcp_listeners,[{"127.0.0.1", 5673},{"::1",       5673}]}

  ]

  },

{rabbitmq_management,

  [

         {listener, [{port,     15673},

            {ip,       "0.0.0.0"},

            {ssl,     false}

         ]}

]}

].

修改完成后，，若是要开启多个实例，参照如下修改配置文件的端口，而后用下面的命令执行便可（注意应同时修改RABBITMQ_NODE_PORT的端口号）：

RABBITMQ_NODE_PORT=5673RABBITMQ_NODENAME=rab /usr/rabbitmq/sbin/rabbitmq-server –detached &

以上步骤是开启了5673端口的一个rabbitmq实例，若是再开启一个实例，那么再修改配置文件：

#vim /etc/rabbitmq/rabbitmq.config

 

[

{rabbit,

  [

  {tcp_listeners, [5672]}

  %%{tcp_listeners, [5672]},

  %%{tcp_listeners,[{"127.0.0.1", 5672},{"::1",       5672}]}

  %%{tcp_listeners,[{"127.0.0.1", 5672},{"::1",       5672}]}

  ]

  }

%%{rabbitmq_management,

 %%[

        %%{listener, [{port,     15673},

     %%       {ip,       "0.0.0.0"},

     %%       {ssl,    false}

        %%]}

%%]}

].

保存退出，

执行命令：/usr/rabbitmq/sbin/rabbitmq-serverstart &便可启动默认端口为5672的服务。

 

 

 

 

若是须要恢复默认的启动方式：

# /usr/rabbitmq/sbin/rabbitmq-server start &

则对应的配置文件为：

#vim /etc/rabbitmq/rabbitmq.config

[

{rabbit,

  [

  {tcp_listeners, [5672]},

  {tcp_listeners,[{"127.0.0.1", 5672},{"::1",       5672}]}

  ]

  }

%%{rabbitmq_management,

 %%[

         %%{listener, [{port,     15673},

     %%       {ip,       "0.0.0.0"},

     %%       {ssl,    false}

         %%]}

%%]}

].
