在开始之前一定要看官方文档,教程不一定是最新的 官方文档:https://www.rabbitmq.com/install-rpm.html 安装Erlang: 本人用yum仓库安装 1)vim /etc/yum.repos.d/rabbitmq-erlang.repo [rabbitmq-erlang] name=rabbitmq-erlang baseurl=https://dl.bintray.com/rabbitmq/rpm/erlang/20/el/7 gpgcheck=1 gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc repo_gpgcheck=0 enabled=1 yum clean all yum makecache 2)然后下载RabbitMQ的rpm包(http://www.rabbitmq.com/download.html) 这里是centos7的版本: wget https://dl.bintray.com/rabbitmq/all/rabbitmq-server/3.7.4/rabbitmq-server-3.7.4-1.el7.noarch.rpm yum install rabbitmq-server-3.7.4-1.el7.noarch.rpm yum会自动去源里安装依赖包
3)优化配置 [root@sh-op-mq01 ~]# cat /etc/security/limits.conf ....... * soft nofile 65535 * hard nofile 65535 [root@sh-op-mq01 ~]# ulimit -n 65535 [root@sh-op-mq01 ~]# vim /etc/sysctl.conf //添加下面一行 fs.file-max = 100000 [root@sh-op-mq01 ~]# sysctl -p 4)启动RabbitMQ [root@sh-op-mq01 ~]# systemctl enable rabbitmq-server.service [root@sh-op-mq01 ~]# systemctl start/restart/stop/status rabbitmq-server.service RabbitMQ默认监听端口是15672 [root@sh-op-mq01 rabbitmq]# lsof -i:15672 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME beam.smp 12776 rabbitmq 50u IPv4 582895 0t0 TCP *:15672 (LISTEN) 默认RabbitMQ的安装目录路径是/var/lib/rabbitmq、默认log路径是/var/log/rabbitmq/ [root@sh-op-mq01 ~]# rabbitmqctl --help [root@sh-op-mq01 ~]# rabbitmqctl status [root@sh-op-mq01 ~]# rabbitmqctl environment 5) 可以自定义RabbitMQ配置 [root@sh-op-mq01 ~]# cd /etc/rabbitmq/ [root@sh-op-mq01 rabbitmq]# cat rabbitmq-env.conf LOG_BASE=/data/log/rabbitmq //定义RabbitMQ的日志路径 [root@sh-op-mq01 rabbitmq]# mkdir /data/log/rabbitmq [root@sh-op-mq01 rabbitmq]# chown -R rabbitmq.rabbitmq /data/log/rabbitmq 6)重启RabbitMQ [root@sh-op-mq01 rabbitmq]# systemctl restart rabbitmq-server.service rabbit-server当前状态: [root@sh-op-mq01 rabbitmq]# rabbitmqctl status Status of node 'rabbit@sh-op-mq01' ...

如果使用默认的guest/guest账号密码登陆不上,解决办法如下 [root@sh-op-mq01 rabbitmq]# vim /etc/rabbitmq/rabbitmq.config [{rabbit, [{loopback_users, []}]}]. [root@sh-op-mq01 rabbitmq]# systemctl restart rabbitmq-server.service 然后使用guest/guest登陆即可! -------------------------------------------------------------------------------- 如果还是使用guest/guest登陆不上RabbitMQ,可以自己创建了一个账户,赋予管理员权限 [root@sh-op-mq01 rabbitmq]# rabbitmqctl add_user username password [root@sh-op-mq01 rabbitmq]# rabbitmqctl set_user_tags username administrator 创建完后用以下命令查看创建完的账号 [root@sh-op-mq01 rabbitmq]# rabbitmqctl list_users
RabbitMQ使用:
1)用户管理 用户管理包括增加用户,删除用户,查看用户列表,修改用户密码,设置用户角色,权限等等。 新增一个用 # rabbitmqctl add_user Username Password 删除一个用户 # rabbitmqctl delete_user Username 修改用户的密码 # rabbitmqctl oldPassword Username newPassword 查看当前用户列表 # rabbitmqctl list_users 赋予角色 # rabbitmqctl set_user_tags zx(用户名) (超级管理员) monitoring(监控者) policymaker(策略制定者) management(普通管理者) 2)用户角色 按照个人理解,用户角色可分为五类,超级管理员, 监控者, 策略制定者, 普通管理者以及其他。 超级管理员(administrator) 可登陆管理控制台(启用management plugin的情况下),可查看所有的信息,并且可以对用户,策略(policy)进行操作。 监控者(monitoring) 可登陆管理控制台(启用management plugin的情况下),同时可以查看rabbitmq节点的相关信息(进程数,内存使用情况,磁盘使用情况等) 策略制定者(policymaker) 可登陆管理控制台(启用management plugin的情况下), 同时可以对policy进行管理。但无法查看节点的相关信息(上图红框标识的部分)。 普通管理者(management) 仅可登陆管理控制台(启用management plugin的情况下),无法看到节点信息,也无法对策略进行管理。 其他 无法登陆管理控制台,通常就是普通的生产者和消费者。
远程连接MQ:
3)远程连接MQ: 创建一个用户 rabbitmqctl add_user zx(名字) zx(密码) 创建一个新的Vhost rabbitmqctl add_vhost test(Vhost名字) 赋予权限 rabbitmqctl set_permissions -p test(Vhost名字) zx(用户) ".*" ".*" ".*" 用户权限 用户权限指的是用户对exchange,queue的操作权限,包括配置权限,读写权限。配置权限会影响到exchange,queue的声明和删除。读写权限影响到从queue里取消息,向 exchange发送消息以及queue和exchange的绑定(bind)操作。 例如: 将queue绑定到某exchange上,需要具有queue的可写权限,以及exchange的可读权限;向exchange发送消息需要具有exchange的可写权限;从queue里取数据需要具有queue的可读权限。详细请参考官方文档中"How permissions work"部分。 相关命令为: (1) 设置用户权限 rabbitmqctl set_permissions -p VHostPath User ConfP WriteP ReadP (2) 查看(指定hostpath)所有用户的权限信息 rabbitmqctl list_permissions [-p VHostPath] (3) 查看指定用户的权限信息 rabbitmqctl list_user_permissions User (4) 清除用户的权限信息 rabbitmqctl clear_permissions [-p VHostPath] User 2.删除用户 rabbitmqctl delete_user username 3.修改密码 rabbitmqctl change_password usernamene wpassword 4.列出所有用户 rabbitmqctl list_users 权限控制: 1.创建虚拟主机 rabbitmqctl add_vhost vhostpath 2.删除虚拟主机 rabbitmqctl delete_vhost vhostpath 3.列出所有虚拟主机 rabbitmqctl list_vhosts 4.设置用户权限 rabbitmqctl set_permissions [-pvhostpath] username regexp regexp regexp 5.清除用户权限 rabbitmqctl clear_permissions [-pvhostpath] username 6.列出虚拟主机上的所有权限 rabbitmqctl list_permissions [-pvhostpath] 7.列出用户权限 rabbitmqctl list_user_permissionsusername
