−
例如我的安装目录是/usr/local/nginx
 
−
修改配置后重新加载生效
 
−
/usr/local/nginx/sbin/nginx -s reload
 
−
重新打开日志文件
 
−
/usr/local/nginx/sbin/nginx -s reopen
 
−
测试nginx配置文件是否正确
 
−
/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
 
−
启动nginx
 
−
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
 
−
快速停止nginx
 
−
/usr/local/nginx/sbin/nginx -s stop
 
−
完整有序的停止nginx
 
−
/usr/local/nginx/sbin/nginx -s quit
 
−
注:stop和quit的区别在于
 
−
quit是一个优雅的关闭方式，Nginx在退出前完成已经接受的连接请求
 
−
Stop 是快速关闭，不管有没有正在处理的请求。
 
  
−
其他的停止nginx 方式：
+
#记得  extra_hosts 改成你的相关IP
−
ps -ef | grep nginx
+
mkdir -p /home/data/docker-compose-mqcluster
 +
cd /home/data/docker-compose-mqcluster
 +
##"登录容器请执行:rabbitmq-plugins enable rabbitmq_management 才可>使用WEB管理页面"
 +
vi docker-compose.yml
  
−
kill -QUIT 主进程号 ：从容停止Nginx

      - "15672:15672"

      - "25672:25672"
  
−
平滑重启nginx：
+
    container_name: rabbitmqCluster01
−
kill -HUP 主进程号
 
  
−
为了方便，现将nginx服务添加至systemctl
+
    hostname: rabbitmq01
−
1.修改nginx配置文件，开启pid
+
    extra_hosts:
−
pid /var/run/nginx.pid;
+
      #- "rabbitmq01:192.168.10.211"#不要加上自己，不然会老是重启的
−
2.通过上述方式关闭nginx服务
+
      - "rabbitmq02:192.168.10.212"
−
3.配置服务,在/usr/lib/systemd/system/nginx.service文件，vim编辑如下
+
      - "rabbitmq03:192.168.10.213"
 +
    environment:
  
−

[Unit]部分主要是对这个服务的说明，内容包括Description和After，Description用于描述服务，After用于描述服务类别

 +

 +
services:
 +
  rabbitmq:
 +
    image: rabbitmq:3.6.10-management
  
−
[Service]部分是服务的关键，是服务的一些具体运行参数的设置，这里Type=forking是后台运行的形式，PIDFile为存放PID的文件路径，ExecStart为服务的具体运行命令，ExecReload为重启命令，ExecStop为停止命令，PrivateTmp=True表示给服务分配独立的临时空间，注意：[Service]部分的启动、重启、停止命令全部要求使用绝对路径，使用相对路径则会报错！

服务脚本按照上面编写完成后，以754的权限保存在/usr/lib/systemd/system目录下
+
    volumes:
−
然后执行(修改或新增文件需要执行以下语句才能生效)
+
      - ./data/rabbitmq:/var/lib/rabbitmq
−
systemctl daemon-reload
+
    restart: always 
−
这时就可以利用systemctl进行配置了
 
−
systemctl start/stop/reload/quit nginx.service
 
−
若发生报错，可通过systemctl status nginx.service查看失败原因
 
−
systemctl enable nginx.service 开机自启动

Php-cgi进程挂掉或者是没有cgi进程

getenforce  #查看SELINUX工作模式

SELINUX=enforcing
 +
#此项定义selinux状态。
 +
#enforcing—是强制模式系统受selinux保护。就是你违反了策略，你就无法继续操作下去
 +
#permissive—是提示模式系统不会受到selinux保护，只是收到警告信息。permissive就是Selinux有效，但是即使你违反了策略的话它让你继续操作，但是把你的违反的内容记录下来(警告信息)
 +
#disabled—禁用selinux。

Rabbitmq常用命令

docker简易搭建RabbitMQ集群HA-good

ins rabbitmq

info

 适合于 3.610 and 3.7.5 版本
-p 15672:15672 http访问端口
-p 5672:5672 amqp访问端口
-p 4369 #unable to connect to epmd (port 4369) on rabbitmq01: address (cannot connect to host/port)

mq1

Note

有一种是 node1 不加别 , node2  add node1  ; node3  add node1 and node2  但是  rabbitmqctl cluster_status 可能看起来有些node alarms是down的 不过通过浏览器的不会

config

将节点2,3加入集群

#在rabbit2机器进入容器的命令行
sudo docker exec -it rabbitmqCluster02 /bin/bash

#加入集群
rabbitmqctl stop_app  && rabbitmqctl join_cluster rabbit@rabbitmq01  &&rabbitmqctl start_app

rabbit3执行相同的命令
docker exec -it rabbitmqCluster03 /bin/bash
rabbitmqctl stop_app && rabbitmqctl join_cluster rabbit@rabbitmq01  &&rabbitmqctl start_app


查询集群状态
rabbitmqctl cluster_status

nginx 配置


#如果是yum nginx  在放在 conf.d/mq.conf
   server {
        listen       80;
        server_name  mq.com;
 

        location / {
            proxy_pass http://10.3.10.141:15672;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header Host $host;

        }
     }


NOTE  selinux  记得关掉  不然可能是502哦 
#SELinux设置
getenforce   #查看SELINUX工作模式

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config #禁用SELINUX
 setenforce 0 #临时禁用SELINUX，无需重启
 
 
 SELINUX=enforcing
#此项定义selinux状态。
#enforcing—是强制模式系统受selinux保护。就是你违反了策略，你就无法继续操作下去
#permissive—是提示模式系统不会受到selinux保护，只是收到警告信息。permissive就是Selinux有效，但是即使你违反了策略的话它让你继续操作，但是把你的违反的内容记录下来(警告信息)
#disabled—禁用selinux。

镜像模式

在我的wiki上 开启镜像模式

RabbitMQ实现延迟队列(使用delay插件


docker cp rabbitmq_delayed_message_exchange-3.6.6.ez   c77afe9fa73f:/plugins


: 进入docker容器内 docker exec  -t rabbit  bash

8. 执行命令让插件生效: 启动延时插件：
rabbitmq-plugins enable rabbitmq_delayed_message_exchange

troubleshooting


1.docker-compose.yml文件报错
ERROR: The Compose file './docker-compose.yml' is invalid because:
services.rabbitmq.environment.CLUSTERED contains true, which is an invalid type, it should be a string, number, or a null


CLUSTERED: true -->CLUSTERED: 'true'


绑hosts的前进 不要全局FQ  SSR常常坑我们 


问题2 
15672 端口不通 也就是web界面打不开 

问题 镜像用了 rabbitmq 而不是rabbitmq-manager

发现过程 web打不开   15672 端口不能 ，而 5672是通的 进入容器发现是ubuntu 而我记得以前是debian呀 问了下sy才知道 他换了，没全用我的，晕死 ，坑自己人啊 

补救办法  开启 rabbitmq-plugins enable rabbitmq_management

https://www.rabbitmq.com/management.html

RabbitMQ镜像集群脑裂


现象：
RabbitMQ GUI上显示

Network partition detected
Mnesia reports that this RabbitMQ cluster has experienced a network partition. There is a risk of losing data. Please read RabbitMQ documentation about network partitions and the possible solutions.


节点3 是挂，以节点1 为准  在 node2  node3 上 分别执行
rabbitmqctl stop_app
rabbitmqctl start_app

就行

端口在 进入容器 cannot exec in a stopped state: unknown

今天是端口在 docker restart id 都不行，进程也还在的 重启了 docker 服务才行了

rabbitmq node not running


行情 重启了一下 docker  mq集群就好了 

试过 telnet  15276 有点不太对 一下就跳出来了  

也登录不了容器  一开始还以为是防火墙

重启 docker 服务  再 如上添加 不过提示 The node is already a member of this cluster  所以应该是重启docker 就好了

今天是 监听的IP不对 模板的是10 我用的 192.168
