安装erlang

cd /tmp
wget http://erlang.org/download/otp_src_18.3.tar.gz
tar -zxvf otp_src_18..tar.gz /opt/otp_src_18.
cd /opt/otp_src_18.
yum -y install gcc glibc-devel make ncurses-devel openssl-devel autoconf
./configure && make && make install
ln -s /usr/local/lib/erlang/bin/erl /usr/bin/.
ln -s /usr/local/lib/erlang/bin/erl /bin/.

note:

安装了erlang ，而且输入erl可以查看到版本号，但是在安装rabbitmq的时候提示没安装erlang或者版本不够，

那么可以用下面代码进行映射，然后忽略rabbitmq的依赖直接安装

ln -s /usr/local/lib/erlang/bin/erl /usr/bin/.
ln -s /usr/local/lib/erlang/bin/erl /bin/.

rabbitmq安装
1. 去https://www.rabbitmq.com/下载rpm

rpm 带 --nodeps 表示安装时忽略依赖

cd /tmp
rpm --import https://www.rabbitmq.com/rabbitmq-signing-key-public.asc
rpm -ivh rabbitmq-server-3.6.-.noarch.rpm --nodeps
service rabbitmq-server restart

rabbitmq 增加用户， web插件

rabbitmqctl add_user jsapi
rabbitmqctl set_user_tags jsapi administrator
rabbitmqctl add_vhost applications
rabbitmqctl set_permissions -p applications jsapi ".*" ".*" ".*"
rabbitmq-plugins enable rabbitmq_management
service rabbitmq-server restart

http://{IP}:15672/

rabbitmq 节点cluster配置

1. 把master， slave的ip分别加入到host中：

a. 查看机子hostname # hostname

b. 修改host # vi /etc/hosts note：如果hostname包含. 那么只要第一个点前面的字符串
masterIP masterHostName
slaveIP slaveHostName

2. 记录下master的cookie： cat /var/lib/rabbitmq/.erlang.cookie

3. 停止slave的rabbitmq： service rabbitmq-server stop

4. 修改slave的cookie为master的： sudo vim /var/lib/rabbitmq/.erlang.cookie

service rabbitmq-server start
rabbitmqctl stop_app
rabbitmqctl join_cluster rabbit@{masterHostName.split(".")[]}
rabbitmqctl start_app

nginx 配置rabbitmq

#/etc/nginx/conf.d/rabbitmq.conf
server {
listen ;
server_name rabbitmq.jobstreet.com;
#access_log /var/log/rabbitmq_access_log main;
#error_log /var/log/rabbitmq_error_log debug_http;
client_max_body_size 60M;
client_body_buffer_size 512k;
location / {
port_in_redirect on;
proxy_pass http://localhost:15672;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

open rabbitmq.jobstreet.com 直接访问note：记得把rabbitmq.jobstreet.com加入到host中
