rabbitmq-server總結

【摘要】總結一下最近一段時間使用rabbitmq-server的經驗，羅列一些相關的資源網站。

問題1：過程和apt-get install rabbitmq-server 差不多，結果和這個差不多。

1. Edit /etc/hostname and /etc/hosts so the hostname in /etc/hostname resolves to 127.0.1.1 or 127.0.0.1 in /etc/hosts.
2. Reboot the machine.
3. Remove rabbitmq-server, chef, and chef-server:
sudo apt-get remove rabbitmq-server
4. Remove this rabbitmq file so it gets properly installed next time:
sudo rm -R /var/lib/rabbitmq
5. Re-install :
sudo apt-get remove rabbitmq-server

這個問題是hostname的問題，應該使hostname和hosts裡面一致。

這裡有個例子Then add that host name to /etc/hosts so it’s possible to resolve it back into an IP address:

127.0.0.1       localhost myhost myhost.local

$ sudo rabbitmqctl status
Status of node [email protected] ...
[{running_applications,[{rabbit,"RabbitMQ","1.7.1"},
                    {mnesia,"MNESIA  CXC 138 12","4.4.12"},
                    {os_mon,"CPO  CXC 138 46","2.2.4"},
                    {sasl,"SASL  CXC 138 11","2.1.8"},
                    {stdlib,"ERTS  CXC 138 10","1.16.4"},
                    {kernel,"ERTS  CXC 138 10","2.13.4"}]},
{nodes,[
 
[email protected]]},
{running_nodes,[[email protected]]}]
...done.

這種適合於DHCP方式。

rabbitmq-server 設定

Setting up RabbitMQ

To use celery we need to create a RabbitMQ user, a virtual host and allow that user access to that virtual host:

$ rabbitmqctl add_user myuser mypassword

$ rabbitmqctl add_vhost myvhost

$ rabbitmqctl set_permissions -p myvhost myuser ".*" ".*" ".*"

Starting/Stopping the RabbitMQ server

To start the server:

$ sudo rabbitmq-server

you can also run it in the background by adding the -detached option (note: only one dash):

$ sudo rabbitmq-server -detached

Never use kill to stop the RabbitMQ server, but rather use the rabbitmqctl command:

$ sudo rabbitmqctl stop

個人感覺rabbitmq-server很傻在安裝前最好測試配置一下 hostname 解析是否正確。

一般我都會寫成這樣

127.0.0.1 localhost
       :: localhost
127.0.0.1  ubuntu	   
192.168.1.100  ubuntu

 然後測試一下 ping ubuntu

再安裝
