nignx修改最大上传文件大小限制

2018-05-14 | Linux | Linux

location / {
            root   html;
            index  index.html index.htm;
            client_max_body_size    1000m;
  }

“client_max_body_size”设置一下上传的最大上限,然后重启nginx即可。

RabbitMQ 三种 Exchange 模式

2018-05-14 | Linux | Linux

RabbitMQ 中的 Exchange（交换机）负责接收生产者发送的消息，并根据类型将消息路由到相应的队列。常见的三种 Exchange 类型如下：

1. Direct Exchange（直连模式） #

✅ 特点： #

根据消息的 routing key 精确匹配，将消息路由到绑定了 相同 routing key 的队列。

🎯 适用场景： #

一对一消息传递。
多个队列分别订阅不同的消息类型。

📌 示例： #

绑定情况：

rabbitmq 消息队列安装和配置

2018-05-14 | Linux | Linux

erlang #

首先安装erlang语言环境

yum install erlang -y

rabbitMQ #

rabbitMQ下载地址：直达安装方法:

rpm -ivh --force --nodeps rabbitmq-server-3.6.0-1.noarch.rpm
或者
yum localinstall  rabbitmq-server-3.6.0-1.noarch.rpm -y

启动服务 #

/etc/init.d/rabbitmq-server start
rabbitmq-plugins enable rabbitmq_management

配置主备 #

同步cookie #

chmod 777 /var/lib/rabbitmq/.erlang.cookie
scp /var/lib/rabbitmq/.erlang.cookie Go02:/var/lib/rabbitmq/.erlang.cookie
chmod 400 /var/lib/rabbitmq/.erlang.cookie

添加节点 #

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster [--ram] rabbit@Go01 //此处的Go01为主节点的hostname,需要在/etc/hosts中指定
rabbitmqctl start_app

删除节点 #

rabbitmqctl stop_app
rabbitmqctl forget_cluster_node rabbit@rabbit1

修改类型 #

rabbitmqctl stop_app
rabbitmqctl change_cluster_node_type ram
rabbitmqctl start_app

添加用户 #

rabbitmqctl add_user admin admin
# 添加权限:
rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*"
# 删除测试用户:
rabbitmqctl delete_user guest
# 赋予其administrator角色：
rabbitmqctl set_user_tags admin administrator
# 修改密码：
rabbitmqctl  change_password  admin  '12341234'

修改配置 #

//防止服务端异常中断恢复后镜像队列不能恢复的问题

vim /etc/rabbitmq/rabbitmq.conf
[
  {rabbit,[{tcp_listeners,[5672]},
  {cluster_partition_handling, autoheal}]}
].
#不要忘记最后面的那个点号哦！

环境变量 #

touch /etc/rabbitmq/rabbitmq-env.conf#输入
    RABBITMQ_NODENAME=FZTEC-240088 节点名称    RABBITMQ_NODE_IP_ADDRESS=127.0.0.1 监听IP
    RABBITMQ_NODE_PORT=5672 监听端口    RABBITMQ_LOG_BASE=/data/rabbitmq/log 日志目录
    RABBITMQ_PLUGINS_DIR=/data/rabbitmq/plugins 插件目录
    RABBITMQ_MNESIA_BASE=/data/rabbitmq/mnesia 后端存储目录

RabbitMQ的用户角色分类 #

none、management、policymaker、monitoring、administrator

RabbitMQ性能优化

2018-05-14 | Linux | Linux

rabbitmq.config #

rabbitmq.config文件时rabbitmq的配置文件，他遵守Erlang配置文件定义。

rabbitmq.config文件位置：

Unix $RABBITMQ_HOME/etc/rabbitmq

Windows %APPDATA%\RabbitMQ\

例子如下：

rabbitmq之机器机器全部断电恢复记录

2018-05-14 | Linux | Linux

今天遇到一个rabbitmq集群同时断电，当机器全部启动的时候发现rabbitmq无法正常启动，然后发现如下日志。

Timeout contacting cluster nodes: ['rabbit@WIN-2W6NDAIZBIA'].

BACKGROUND
==========

This cluster node was shut down while other nodes were still running.
To avoid losing data, you should start the other nodes first, then
start this one. To force this node to start, first invoke
"rabbitmqctl force_boot". If you do so, any changes made on other
cluster nodes after this one was shut down may be lost.

DIAGNOSTICS
===========

attempted to contact: ['rabbit@WIN-2W6NDAIZBIA']

rabbit@WIN-2W6NDAIZBIA:
  * connected to epmd (port 4369) on WIN-2W6NDAIZBIA
  * epmd reports: node 'rabbit' not running at all
                  no other nodes on WIN-2W6NDAIZBIA
  * suggestion: start the node

current node details:
- node name: 'rabbit@WIN-ACC2J7AGNM9'
- home dir: C:\Users\Administrator
- cookie hash: kR4NuIdBr2n8/4Qt9uIgqQ==
