        官网:

        https://www.rabbitmq.com/install-standalone-mac.html

 

       

安装erlang语言环境

安装依赖文件

yum install ncurses-devel
yum -y install openssl
yum -y install ssl

yum -y install xmlto
yum -y install python-simplejson
yum -y install python

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

wget http://www.erlang.org/download/otp_src_17.5.tar.gz
tar zxvf otp_src_17.5.tar.gz
cd otp_src_17.5

阅读HOTO/INSTALL.md文件

./configure
make && make install

安装完成以后,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@iZ113aowxo2Z ~]# erl
Erlang/OTP 17 [erts-6.4] [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]
Eshell V6.4 (abort with ^G)
1> 9+1.
10
2> halt().

安装RabbitMQ

安装依赖

yum install xmlto

创建主文件夹

mkdir rabbitmq
cd rabbitmq

直接使用RPM

wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.0/rabbitmq-server-3.6.0-1.noarch.rpm
rpm -ivh rabbitmq-server-3.6.0-1.noarch.rpm

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

wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.0/rabbitmq-server-3.6.0.tar.xz
xz -d rabbitmq-server-3.6.0.tar.xz
tar xvf rabbitmq-server-3.6.0.tar
cd rabbitmq-server-3.6.0
make
make install TARGET_DIR=/opt/rabbitmq SBIN_DIR=/opt/rabbitmq/sbin MAN_DIR=/opt/rabbitmq/man DOC_INSTALL_DIR=/opt/rabbitmq/doc

使用

启动MQ

rabbitmq-server -detached

查看状态

rabbitmqctl status

启用管理插件

mkdir /etc/rabbitmq/
rabbitmq-plugins enable rabbitmq_management

停止服务

rabbitmqctl stop

添加账号
PS:默认账号guest只能在localhost访问

rabbitmqctl add_user admin admin

设置管理员

rabbitmqctl set_user_tags admin administrator

设置读写权限
命令使用户admin具有/vhost1这个virtual host中所有资源的配置、写、读权限以便管理其中的资源

rabbitmqctl set_permissions -p /vhost1 admin ‘.‘ ‘.‘ ‘.*’

查看账号

rabbitmqctl list_users

加入账号到配置

vi /etc/rabbitmq/rabbitmq.config
[
{rabbit, [{loopback_users, [“admin”]}]}
].

重启后 http://ip:15672 登录管理界面了

64位CentOS6.2安装erlang及rabbitmqServer

CentOS 6.2 64bit 安装erlang及RabbitMQ Server

1、操作系统环境(CentOS 6.2 64bit)

[root@leekwen ~]# cat /etc/issue
CentOS release 6.2 (Final)
Kernel \r on an \m
[root@leekwen ~]# cat /proc/cpuinfo grep "clflush size"
clflush size    : 64
clflush size    : 64
clflush size    : 64
clflush size    : 64
clflush size    : 64
clflush size    : 64
clflush size    : 64
clflush size    : 64
2、安装erlang依赖的基本环境
[root@leekwen ~]# yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel
3、导入erlang源,并安装erlang
[root@leekwen ~]# rpm --import http://binaries.erlang-solutions.com/debian/erlang_solutions.asc

5、下载并安装rabbitmq-server  
[root@leekwen ~]# wget -c http://www.rabbitmq.com/releases/rabbitmq-server/v3.3.0/rabbitmq-server-3.3.0-1.noarch.rpm

6、启动rabbitmq-server
[root@leekwen ~]# /etc/init.d/rabbitmq-server start
Starting rabbitmq-server:
FAILED - check /var/log/rabbitmq/startup_{log, _err}
rabbitmq-server.
[root@leekwen ~]# cat /var/log/rabbitmq/startup_err
[root@leekwen ~]# cat /var/log/rabbitmq/startup_log
ERROR: epmd error for host leekwen: address (cannot connect to host/port)
[root@leekwen ~]# hostname
leekwen
[root@leekwen ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=leekwen
[root@leekwen ~]# cat /etc/hosts
127.0.0.1       localhost
127.0.0.1       leekwen
::1             localhost
7、以上操作排除了因为主机名不同导致RabbitMQ-Server启动报错的问题,请修改主机名(参见上述步骤),再次启动RabbitMQ-Server
[root@leekwen ~]# /etc/init.d/rabbitmq-server restart
Restarting rabbitmq-server: RabbitMQ is not running
FAILED - check /var/log/rabbitmq/startup_{log, _err}
rabbitmq-server.
8、结果同样报错,查看错误的日志:

9、出现如上的错误,可能是因为5672端口已经被占用的原因。
查看5672端口的情况,如果有进程占用此端口,请将它关闭后,重新启动RabbitMQ-Server;
[root@leekwen ~]# netstat -atn grep 5672

就可以用guest,guest登陆http://192.168.1.101:15672端口了。

注意:如果此时你从端口15672或55672登陆不了,请关闭CentOS6.2的防火墙,再次登陆,

如果仍然出现无法登陆的想象,查看日志后,显示:

=ERROR REPORT==== 20-Apr-2014::00:55:15 ===
webmachine error: path="api/whoami"
"Unauthorized"
那么请运行如下的命令,增加用户admin,密码admin即可。  
[root@leekwen ~]# rabbitmqctl add_user admin admin
Creating user "admin" ...
...done.
[root@leekwen ~]# rabbitmqctl list_users
Listing users ...
admin   []
guest   [administrator]
...done.
[root@leekwen ~]# rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...
...done.
[root@leekwen ~]# rabbitmqctl list_users
Listing users ...
admin   [administrator]
guest   [administrator]
...done.
到此,配置完成。
