RabbitMQ安装

Ubuntu上只能源码安装Erlang,RabbitMQ和各种相关依赖，无法使用yum,rpm等方式！

源码安装Erlang和RabbitMQ:

注意只要安装了Erlang环境，RabbitMQ解压后即可使用，无需安装！！Web插件安装需要在rabbitmq-server启动条件下进行。启动后需要将防火墙开启5672和15672默认端口才可远程访问。默认guest用户无法远程访问，需要按照博客中介绍的重新创建一个用于administrator权限的admin用户才行。

最新的19.3及以上的erlang包，虽然是tar.gz结尾，并没有使用gzip压缩，tar zxvf会报错！！去掉z参数，直接使用tar xvf即可解包，一定注意！！

最新的RabbitMQ选择generic-unix版本的xz包（debian的gz包坑爹，只有几K），关于xz包如何解压的问题：

Erlang安装缺少ncurses依赖，也要源码安装，我的Ubuntu16.04LTS需要安装ncurses6.1源码版本才能成功：

Erlang的configure检查时提示找不到openssl,但没有报错，可以正常安装，Ubuntu也带了openssl，安装新版本zlib和openssl并生效请参照前面安装Nginx的文章！！

常见的修复安装命令：用于一些包源码安装时缺少依赖，只要在安装命令执行后紧接着再执行一下下面的命令（不用带上包名）

sudo apt-get -f install

最后所有的/etc/profiles中环境变量配置，包括openssl,erlang,rabbitmq（注意PATH=$PATH:XXX这种只能出现一次，写在所有环境变量配置的最后！否则后面写的覆盖前面的，前面的环境变量就无效了！！）：

export OPENSSL=/usr/local/openssl/bin
export PATH=$OPENSSL:$PATH:$HOME/bin
ERLANG_HOME=/opt/erlang
RABBITMQ_HOME=/opt/rabbitmq_server-3.6.10
export PATH=$PATH:$ERLANG_HOME/bin:$RABBITMQ_HOME/sbin
export ERLANG_HOME
export RABBITMQ_HOME

Ubuntu普通用户在任意目录启动rabbit-server，提示错误：

baigang@baigang-virtual-machine:/opt$ which rabbitmq-server
/opt/rabbitmq_server-3.6.10/sbin/rabbitmq-server
baigang@baigang-virtual-machine:/opt$ rabbitmq-server &
[1] 53456
baigang@baigang-virtual-machine:/opt$ /opt/rabbitmq_server-3.6.10/sbin/rabbitmq-server: 51: /opt/rabbitmq_server-3.6.10/sbin/rabbitmq-server: cannot create /opt/rabbitmq_server-3.6.10/var/lib/rabbitmq/mnesia/rabbit@baigang-virtual-machine.pid: Permission denied
Failed to write pid file: /opt/rabbitmq_server-3.6.10/var/lib/rabbitmq/mnesia/rabbit@baigang-virtual-machine.pid

[1]+  Exit 73                 rabbitmq-server

这是由于普通用户在/opt的各层目录和文件默认都没有写权限，所以无法写入rabbitmq的pid造成启动失败，解决办法是在错误提示的各层目录都使用sudo chmod a+w xxx目录命令为普通用户添加目录写权限，最后在已经生成的pid文件也使用sudo chmod a+w xxx.pid为普通用户添加文件写命令！

启动成功：

服务开启情况下Web插件的安装：同样遇到无法创建文件问题，仍然是没有权限，解决办法参照上面服务器安装的pid创建权限问题

baigang@baigang-virtual-machine:/opt/rabbitmq_server-3.6.10/etc/rabbitmq$ rabbitmq-plugins enable rabbitmq_management
Plugin configuration unchanged.

Applying plugin configuration to rabbit@baigang-virtual-machine... nothing to do.
baigang@baigang-virtual-machine:/opt/rabbitmq_server-3.6.10/etc/rabbitmq$

然后可以通过默认15672端口Web监控页面正常访问。
