Rabbit MQ 安装(二)
1.此环境为CentOS
2.所有安装在目录/var/erlang/，注意安装目录，以及环境配置目录
1.安装依赖：
yum -y install gcc glibc-devel make ncurses-devel openssl-devel xmlto perl wget
2.安装erlang语言环境：
1.下载erlang包，可能会等待很久：
wget http://www.erlang.org/download/otp_src_18.3.tar.gz
2.解压.gz包：
tar -xzvf otp_src_18.3.tar.gz
3.切换到安装路径：
cd otp_src_18.3
4.生产安装配置：
./configure --prefix=/var/erlang/
5.编辑安装：
make && make install
3.配置erlang环境变量：
1.打开/etc/profile文件，添加环境变量：
# 在文件最下面，添加以下内容
ERL_HOME=/var/erlang
PATH=$ERL_HOME/bin:$PATH
export ERL_HOME PATH
2.将配置文件及时生效：
source /etc/profile
3.测试是否成功，输出erl，如果出现以下内容，说明安装成功，ctrl + c 退出即可：
erl
Erlang/OTP 18 [erts-7.3] [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]
Eshell V7.3 (abort with ^G)
1>
4.下载、安装Rabbit MQ:
1.下载解压，切换cd /var/erlang目录：
cd /var/erlang
2.下载RabbitMQ安装包：
wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.1/rabbitmq-server-generic-unix-3.6.1.tar.xz
3.解压安装包：
xz -d rabbitmq-server-generic-unix-3.6.1.tar.xz //解压.xz包
tar -xvf rabbitmq-server-generic-unix-3.6.1.tar //解压.tar包
5.配置环境变量：
1.打开/etc/profile文件，添加环境变量：
vim /etc/profile
# 将下面的配置到此文件中
# set rabbitmq environment
export PATH=$PATH:/var/erlang/rabbitmq_server-3.6.1/sbin
2.将配置文件及时生效：
source /etc/profile
6.启动服务：
1.启动服务器：
rabbitmq-server -detached // -detached 代表后台守护进程方式启动
Warning: PID file not written; -detached was passed.
2.查看状态，rabbitmqctl status：
rabbitmqctl status
Status of node rabbit@bogon ...

3.关闭服务器：
rabbitmqctl stop
7.安装网页插件：
# 在/etc/rabbitmq 新创建目录
erlang mkdir /etc/rabbitmq
1.启动插件：
rabbitmq-plugins enable rabbitmq_management // rabbitmq_management插件名
rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
mochiweb
webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management
Applying plugin configuration to rabbit@bogon... started 6 plugins.
2.关闭插件：
rabbitmq-plugins disable rabbitmq_management
8.配置访问账号和密码：
1.添加用户，后面两个参数分别是用户名、密码：
# 创建用户名为root、密码是 lv6913540
rabbitmqctl add_user root lv6913540
Creating user "root" ...
2.新创建用户，赋予administrator角色，否则登录失败：
# 给用户名为root的添加 administrator权限
rabbitmqctl set_user_tags root administrator
3.创建rabbitMQ监控用户，负责整个MQ的监控：
rabbitmqctl add_user lvhuiqi lvhuiqi
rabbitmqctl set_user_tags lvhuiqi monitoring // 执行命令
4.查看当前用户列表，以及负责的角色：
rabbitmqctl list_users // 执行命令
Listing users ...
lvhuiqi [monitoring] // 监控权限
guest [administrator]
root [administrator] // 管理员权限
5.删除用户：
rabbitmqctl delete_user Username
6.修改用户的密码：
rabbitmqctl change_password Username Newpassword
注意：登录时，必须给新创建的用户赋予角色，否则用户无权登录。
9.访问地址：
http://[ip地址]:15672，注意环境的防火墙是否关闭。
