1 環(huán)境
兩個(gè)節(jié)點(diǎn)
172.17.164.17 rabbitmq-node1 #centos6.4
172.17.164.18 rabbitmq-node2 #centos6.4
1.1 修改hostname
修改3個(gè)地方
/etc/hosts
172.17.164.17 rabbitmq-node1
172.17.164.18 rabbitmq-node2
/etc/sysconfig/network
HOSTNAME=rabbitmq-node1
HOSTNAME=rabbitmq-node2
如果不想重啟蜗细，直接修改hostname肖油，重新登陸即可
[root@localhost ~]# hostname rabbitmq-node1
2 安裝erlang和mq
2.1 安裝erlang依賴(lài)的基本環(huán)境
yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel
2.2 導(dǎo)入erlang源膛锭，并安裝erlang
[root@localhost ~]# rpm --import http://binaries.erlang-solutions.com/debian/erlang_solutions.asc
[root@localhost ~]# wget -O /etc/yum.repos.d/erlang_solutions.repo http://binaries.erlang-solutions.com/rpm/centos/erlang_solutions.repo
[root@localhost ~]# wget http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
[root@localhost ~]# rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
[root@localhost ~]# rpm -i rpmforge-release-0.5.2-2.el6.rf.*.rpm
[root@localhost ~]# yum update
[root@localhost ~]# yum update --skip-broken
[root@localhost ~]# yum install erlang
2.3 安裝rabbitmq
[root@localhost ~]# wget -c http://www.rabbitmq.com/releases/rabbitmq-server/v3.3.0/rabbitmq-server-3.3.0-1.noarch.rpm
[root@localhost ~]# yum -y install rabbitmq-server-3.3.0-1.noarch.rpm
#啟動(dòng)
[root@rabbitmq-node1 ~]# /etc/init.d/rabbitmq-server start
Starting rabbitmq-server: SUCCESS
rabbitmq-server.
[root@rabbitmq-node1 ~]# rabbitmqctl status

2.4 安裝插件管理界面
[root@rabbitmq-node1 ~]# mkdir -m 777 /etc/rabbitmq/
#如果目錄已經(jīng)存在直接執(zhí)行
[root@rabbitmq-node1 ~]# chmod 777 /etc/rabbitmq/
[root@rabbitmq-node1 ~]# rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
mochiweb
webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management
Plugin configuration has changed. Restart RabbitMQ for changes to take effect.
#重啟rabbitmq-server
[root@rabbitmq-node1 ~]# rabbitmqctl stop
Stopping and halting node 'rabbit@rabbitmq-node1' ...
...done.
[root@rabbitmq-node1 ~]# /etc/init.d/rabbitmq-server start
Starting rabbitmq-server: SUCCESS
rabbitmq-server.
#查看管理端口有沒(méi)有啟動(dòng)：
[root@rabbitmq-node1 ~]# netstat -tnlp|grep 15672
瀏覽器打開(kāi)http://IP:15672 賬號(hào)密碼都是guest揩悄。
注意：rabbitmq從3.3.0開(kāi)始禁止使用guest/guest權(quán)限通過(guò)除localhost外的訪問(wèn)笤受。
如果想使用guest/guest通過(guò)遠(yuǎn)程機(jī)器訪問(wèn)淀弹，需要在rabbitmq配置文件中(/etc/rabbitmq/rabbitmq.config)中設(shè)置loopback_users為[]。
/etc/rabbitmq/rabbitmq.config文件完整內(nèi)容如下（注意后面的半角句號(hào)）：
[{rabbit, [{loopback_users, []}]}].
2.5 添加管理用戶
我們不設(shè)置guest遠(yuǎn)程訪問(wèn)了拾枣。
使用命令添加一個(gè)新的管理賬號(hào)(每個(gè)節(jié)點(diǎn)都要配置)：
[root@rabbitmq-node1 ~]# rabbitmqctl add_user admin htxx51fpmq
Creating user "admin" ...
...done.
#賦予管理員權(quán)限：
[root@rabbitmq-node1 ~]# rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...
...done.
#重啟服務(wù)
[root@rabbitmq-node1 ~]# /etc/init.d/rabbitmq-server restart
Restarting rabbitmq-server: SUCCESS
rabbitmq-server.
2.6 開(kāi)放端口
[root@rabbitmq-node2 ~]# /sbin/iptables -I INPUT -p tcp --dport 5672 -j ACCEPT
[root@rabbitmq-node2 ~]# /sbin/iptables -I INPUT -p tcp --dport 15672 -j ACCEPT
[root@rabbitmq-node2 ~]# /etc/rc.d/init.d/iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]
[root@rabbitmq-node2 ~]# /etc/init.d/iptables restart
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
iptables: Applying firewall rules: [ OK ]
[root@rabbitmq-node2 ~]# /etc/init.d/iptables status
3 配置集群
3.1 設(shè)置 Erlang Cookie
Erlang Cookie 文件：/var/lib/rabbitmq/.erlang.cookie沃疮。這里將 node1 的該文件復(fù)制到 node2。由于這個(gè)文件權(quán)限是 400梅肤，所以需要先修改 node2中的該文件權(quán)限為 777：
[root@rabbitmq-node2 ~]# chmod 777 /var/lib/rabbitmq/.erlang.cookie
[root@rabbitmq-node1 ~]# scp -P 26622 /var/lib/rabbitmq/.erlang.cookie root@172.17.164.18:/var/lib/rabbitmq/.erlang.cookie
然后將 node1 中的該文件拷貝到 node2司蔬，最后將權(quán)限和所屬用戶/組修改回來(lái)：
[root@rabbitmq-node2 ~]# chmod 400 /var/lib/rabbitmq/.erlang.cookie
3.2 使用 -detached 參數(shù)運(yùn)行各節(jié)點(diǎn)
[root@rabbitmq-node1 ~]#rabbitmqctl stop
[root@rabbitmq-node1 ~]# rabbitmq-server -detached
3.3 組成集群
將 node2 與 node1 組成集群：
[root@rabbitmq-node2 ~]# rabbitmqctl stop_app
[root@rabbitmq-node2 ~]# rabbitmqctl join_cluster rabbit@node1
[root@rabbitmq-node2 ~]# rabbitmqctl start_app
如果要使用內(nèi)存節(jié)點(diǎn)，則可以使用
node2 # rabbitmqctl join_cluster --ram rabbit@rabbitmq-node1 加入集群姨蝴。
集群配置好后俊啼，可以在 RabbitMQ 任意節(jié)點(diǎn)上執(zhí)行 rabbitmqctl cluster_status 來(lái)查看是否集群配置成功。
3.4 將rabbitmq設(shè)為開(kāi)機(jī)自啟動(dòng)
[root@rabbitmq-node1 ~]# chkconfig --level 35 rabbitmq-server on
