RabbitMQ群集搭建(源码)
实验环境
192.168.3.110 rabbitmq-test1 192.168.3.120 rabbitmq-test2
2.修改主机名
[root@rabbitmq-test1 ~]# cat /etc/hosts 192.168.3.110 rabbitmq-test1 rabbitmq-test1.com 192.168.3.120 rabbitmq-test2 rabbitmq-test2.com
3.安装rabbitmq所依赖环境
[root@rabbitmq-test1 ~]# ntpdate pool.ntp.org 30 Jan 16:54:07 ntpdate[1592]: step time server 202.112.29.82 offset 1894159.715134 sec [root@rabbitmq-test1 ~]# rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm Retrieving http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm warning: /var/tmp/rpm-tmp.qlPeIE: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEY Preparing... ########################################### [100%] 1:epel-release ########################################### [100%] [root@rabbitmq-test1 ~]# yum -y install gcc gcc-c++ ncurses-devel
4.Rabbitmq基于erlang语言开发，需要安装erlang虚拟机
[root@rabbitmq-test1 ~]# wget http://www.erlang.org/download/otp_src_R16B01.tar.gz [root@rabbitmq-test1 ~]# tar zxvf otp_src_R16B01.tar.gz [root@rabbitmq-test1 ~]# cd otp_src_R16B01 [root@rabbitmq-test1 otp_src_R16B01]#./configure && make && make install
5.安装rabbitmq源码包，该源码包已经编译好，可直接使用
[root@rabbitmq-test1 ~]# wget [root@rabbitmq-test1 src]# tar zxvf rabbitmq-server-generic-unix-3.4.3.tar.gz [root@rabbitmq-test1 src]# ln -svf /usr/local/src/rabbitmq_server-3.4.3 /usr/local/rabbitmq-node1 [root@rabbitmq-test1 ~]# vim ~/.bash_profile export PATH=$PATH:$HOME/bin:/usr/local/rabbitmq-node1/sbin/:$PATH [root@rabbitmq-test1 ~]# source ~/.bash_profile [root@rabbitmq-test1 ~]# rabbitmq-plugins enable rabbitmq_management #开启插件 [root@rabbitmq-test1 ~]# rabbitmq-plugins list Configured: E = explicitly enabled; e = implicitly enabled | Status: [failed to contact rabbit@rabbitmq-test1 - status not shown] |/ [e ] amqp_client 3.4.3 [ ] cowboy 0.5.0-rmq3.4.3-git4b93c2d [e ] mochiweb 2.7.0-rmq3.4.3-git680dba8 [ ] rabbitmq_amqp1_0 3.4.3 [ ] rabbitmq_auth_backend_ldap 3.4.3 [ ] rabbitmq_auth_mechanism_ssl 3.4.3 [ ] rabbitmq_consistent_hash_exchange 3.4.3 [ ] rabbitmq_federation 3.4.3 ...... 重启rabbitmq使得插件生效 [root@rabbitmq-test1 ~]# rabbitmqctl stop [root@rabbitmq-test1 ~]# rabbitmq-server -detached 6.配置集群 [root@rabbitmq-test1 ~]# scp -P 8022 .erlang.cookie [email protected]:/root/ [root@rabbitmq-test2 ~]# rabbitmqctl status #当把.erlang文件传过去后，可能会报错，所以需要重启 Status of node 'rabbit@rabbitmq-test2' ... Error: unable to connect to node 'rabbit@rabbitmq-test2': nodedown DIAGNOSTICS =========== attempted to contact: ['rabbit@rabbitmq-test2'] rabbit@rabbitmq-test2: * connected to epmd (port 4369) on rabbitmq-test2 * epmd reports node 'rabbit' running on port 25672 * TCP connection succeeded but Erlang distribution failed * suggestion: hostname mismatch? * suggestion: is the cookie set correctly? current node details: - node name: 'rabbitmqctl-54368@rabbitmq-test2' - home dir: /root - cookie hash: adFjoR3CB/7hub0ns+opnw== [root@rabbitmq-test2 ~]# ps -ef | grep rabbitmq | grep -v "grep" [root@rabbitmq-test2 ~]# kill -9 54239 [root@rabbitmq-test1 ~]# rabbitmqctl join_cluster rabbit@rabbitmq-test2 Clustering node 'rabbit@rabbitmq-test1' with 'rabbitmq-test2' ...

7.修改默认密码
root@rabbitmq-test1 ~]# rabbitmqctl change_password guest kaibin Changing password for user "guest" ...
8.登陆网页管理界面
http://localhost:15672
9.处于安全的考虑，guest这个默认的用户只能通过localhost来登录，其他的IP无法直接使用这个账号
为了解决这个问题，需要在rabbitmq的配置文件中将loopback_users配置设置为空，如编写配置文件:/etc/rabbitmq/rabbitmq.config，并在其中添加以下内容：
[root@rabbitmq-test1 ~]# mkdir /etc/rabbitmq
[root@rabbitmq-test1 ~]# vim /etc/rabbitmq/rabbitmq.conf
[{rabbit, [{loopback_users, []}]}].
方案二:
[root@rabbitmq-node2 ~]# cat /usr/local/rabbitmq-node2/ebin/rabbit.app | grep guest --color
{default_user,<<"guest">>},
{default_pass,<<"guest">>},
{loopback_users,[<<"guest">>]},
将loopback_users本地用户删掉
[root@rabbitmq-node2 ~]# cat /usr/local/rabbitmq-node2/ebin/rabbit.app | grep loopback --color
{loopback_users,[<<"">>]},
