环境搭建---部署rabbitmq集群

rabbitmq下载：https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.34/rabbitmq-server-generic-unix-3.8.34.tar.xz
erlang下载：https://github.com/erlang/otp/releases/download/OTP-24.3.4.1/otp_src_24.3.4.1.tar.gz

配置主机名

[root@zhcs-cvm-01]# hostnamectl set-hostname zhcs-cvm-01
[root@zhcs-cvm-01]# hostname zhcs-cvm-01
[root@zhcs-cvm-02]# hostnamectl set-hostname zhcs-cvm-02
[root@zhcs-cvm-02]# hostname zhcs-cvm-02
[root@zhcs-cvm-03]# hostnamectl set-hostname zhcs-cvm-03
[root@zhcs-cvm-03]# hostname zhcs-cvm-03

配置hosts文件

[root@zhcs-cvm-01 sbin]# cat /etc/hosts
10.206.0.44 zhcs-cvm-01
10.206.0.45 zhcs-cvm-02
10.206.1.46 zhcs-cvm-03
[root@zhcs-cvm-02 sbin]# cat /etc/hosts
10.206.0.44 zhcs-cvm-01
10.206.0.45 zhcs-cvm-02
10.206.1.46 zhcs-cvm-03
[root@zhcs-cvm-03 sbin]# cat /etc/hosts
10.206.0.44 zhcs-cvm-01
10.206.0.45 zhcs-cvm-02
10.206.1.46 zhcs-cvm-03

配置免密登陆：（三台均配置）

[root@zhcs-cvm-01]# ssh-keygen -t rsa
[root@zhcs-cvm-01]# cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
[root@zhcs-cvm-01]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@zhcs-cvm-02
[root@zhcs-cvm-01]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@zhcs-cvm-03

安装erlang：

[root@zhcs-cvm-01]# tar -xf otp_src_24.3.4.1.tar.gz
[root@zhcs-cvm-01]# cd otp_src_24.3.4.1/
[root@zhcs-cvm-01]# ./configure --prefix=/opt/erlang
[root@zhcs-cvm-01]# make && make install
[root@zhcs-cvm-01]# vim /etc/profile
ERL_HOME=/opt/erlang
PATH=$ERL_HOME/bin:$PATH
export ERL_HOME PATH
[root@zhcs-cvm-01]# source /etc/profile

同步cookie文件

[root@zhcs-cvm-01]# scp /root/.erlang.cookie root@zhcs-cvm-02:/root/.erlang.cookie 
[root@zhcs-cvm-01]# scp /root/.erlang.cookie root@zhcs-cvm-03:/root/.erlang.cookie 

安装rabbitmq：

三台均操作：

[root@zhcs-cvm-01]# tar -xf rabbitmq-server-generic-unix-3.8.34.tar.xz
[root@zhcs-cvm-01]# cd rabbitmq_server-3.8.34
[root@zhcs-cvm-01]# ./sbin/rabbitmq-plugins enable rabbitmq_management
[root@zhcs-cvm-01]# ./sbin/rabbitmq-server -detached

只在其他节点操作：

[root@zhcs-cvm-01 sbin]# ./rabbitmqctl stop_app
[root@zhcs-cvm-01 sbin]# ./rabbitmqctl reset
[root@zhcs-cvm-01 sbin]# ./rabbitmqctl join_cluster rabbit@zhcs-cvm-01
[root@zhcs-cvm-01 sbin]# ./rabbitmqctl start_app

创建用户授权

[root@zhcs-cvm-01 sbin]# ./rabbitmqctl add_user admin password
[root@zhcs-cvm-01 sbin]# ./rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
[root@zhcs-cvm-01 sbin]# ./rabbitmqctl set_user_tags admin administrator

rabbitmqctl set_permissions --vhost   

虚拟主机 用户名 “对哪些实体有配置权限” “对哪些实体有写权限” “对哪些实体有读权限”

rabbitmqctl set_permissions --vhost "/" fkjava ".*" ".*" ".*"
