安装
1 安装erlang
依赖：
yum install lrzsz vim -y yum install ncurses ncurses-base ncurses-devel ncurses-libs ncurses-static ncurses-term ocaml-curses ocaml-curses-devel openssl-devel zlib-devel -y yum install -y gcc gcc-c++ yum install -y unixODBC unixODBC-devel yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel gtk2-devel binutils-devel
RabbitMQ Erlang版本兼容：http://www.rabbitmq.com/which-erlang.html
Erlang各版本下载界面：http://erlang.org/download/
# tar -zxvf otp_src_22.3.tar.gz # cd otp_src_22.3/ # ./configure --prefix=/usr/local/erlang --with-ssl -enable-threads -enable-smmp-support -enable-kernel-poll --enable-hipe --without-javac # make && make install
make报错
下载 wxWidgets-3.0.5.tar.bz2 # yum install bzip2 -y # yum install -y mesa* freeglut* # bzip2 -d wxWidgets-3.0.5.tar.bz2 # tar -xvf wxWidgets-3.0.5.tar # cd wxWidgets-3.0.5 # ./configure --with-opengl --enable-debug --enable-unicode # make && make install 重新编译安装 erlang
配置环境变量
# vim /etc/profile ERL_HOME=/usr/local/erlang export PATH=${ERL_HOME}/bin:$PATH # source /etc/profile # echo $ERL_HOME [root@localhost otp_src_22.3]# erl Erlang/OTP 22 [erts-10.7] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe] Eshell V10.7 (abort with ^G) 1> halt().
2 安装 mq

3 拷贝文件以及启动

这里第二节点加入失败，检查 Erlang cookie hash 始终不正确，

上面我标注的2个地方不正确
搞了一会，我发现我的mq2节点之前再集群启动的时候 ，启动过一次，导致重新加入失败
所以：要清除数据目录，再重新启动
[root@mq2 rabbitmq]# cd mnesia/ [root@mq2 mnesia]# rm -rf * [root@mq2 mnesia]# systemctl start rabbitmq-server [root@mq2 mnesia]# rabbitmqctl cluster_status Cluster status of node rabbit@mq2 ...

后续操作都ok了

如果要配置为镜像模式
可以通过命令行或者web页面配置
[root@rabbit1 ~]# rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'
