RabbitMQ提供…一、概述
一般情况下可以使用默认的内建配置来有效地运行RabbitMQ并且大多数情况下也并不需要修改任何 RabbitMQ的配置。当然为了更加有效地操控 RabbitMQ也可以利用调节系统范围内的参数来达到定制化的需求。
RabbitMQ提供了三种方式来定制化服务 (1)环境变量Enviroment Variables )。RabbitMQ服务端参数可以通过环境变量进行配置 例如节点名称、RabbitMQ配置文件的地址、节点内部通信端口等。 (2配置文件Configuration File )。可以定义 RabbitMQ服务和插件设置例如TCP监听端口以及其他网络相关的设置、内存限制、磁盘限制等。 (3运行时参数和策略Runtime Parameters and Policies)。可以在运行时定义集群层面的服务设置。
对于不同的操作系统和不同的RabbitMQ安装包来说相应的配置会有所变化包括相应的配置文件的地址等在使用时要尤为注意。
二、环境变量
2.1 手动设置的环境变量
还记得我们在第一节【 3分钟在Linux上安装RabbitMQ】其中就手动设置了两个环境变量RABBITMQ_USERNAME和RABBITMQ_PASSWORD 定义了超级管理员的账号和密码这样我们就能通过这个账号登录管理后台
docker run -d --name rabbitmq \
-e RABBITMQ_USERNAMEadmin \
-e RABBITMQ_PASSWORDadmin \
-p 15672:15672 -p 5672:5672 -p 25672:25672 -p 61613:61613 -p 1883:1883 bitnami/rabbitmq进入docker容器看一下关于RABBITMQ现在有哪些环境变量
I have no name!0d5cb60e3a06:/$ env | grep RABBIT
RABBITMQ_PASSWORDadmin
RABBITMQ_USERNAMEadmin三、变量配置文件rabbitmq-env.conf
rabbitmq-env.conf配置文件所在目录为/etc/rabbitmq
I have no name!0d5cb60e3a06:/etc/rabbitmq$ ls -al
total 12
drwxrwxr-x. 1 root root 75 Sep 25 05:23 .
drwxr-xr-x. 1 root root 22 Dec 2 2021 ..
-rw-r--r--. 1 1001 root 41 Sep 25 05:23 enabled_plugins
-rw-r--r--. 1 1001 root 560 Sep 20 12:33 rabbitmq.conf
-rw-r--r--. 1 1001 root 78 Sep 20 12:33 rabbitmq-env.conf查看一下该配置文件配置了些啥
I have no name!0d5cb60e3a06:/etc/rabbitmq$ cat rabbitmq-env.conf
HOME/opt/bitnami/rabbitmq/.rabbitmq
NODE_PORT5672
NODENAMErabbitlocalhost默认的配置就上面的HOME目录端口以及节点名称 如何配置这个文件呢如果想改端口为5673改成NODE_PORT5673即可。如果想添加一个变量值同样的在最下面就可以直接添加。可以看到这里的变量名是不带RABBITMQ前缀的。
四、默认的取值规则文件rabbitmq-defaults
该文件一般是在$RABBITMQ_HOME/sbin下面 本示例所在的目录是/opt/bitnami/rabbitmq/sbin下面
I have no name!0d5cb60e3a06:/opt/bitnami/rabbitmq/sbin$ ls -al
total 48
drwxrwxr-x. 1 root root 238 Dec 2 2021 .
drwxr-xr-x. 1 root root 45 Jan 4 2022 ..
-rwxrwxr-x. 1 root root 855 Dec 2 2021 rabbitmqctl
-rwxrwxr-x. 1 root root 609 Dec 2 2021 rabbitmq-defaults
-rwxrwxr-x. 1 root root 864 Dec 2 2021 rabbitmq-diagnostics
-rwxrwxr-x. 1 root root 6887 Dec 2 2021 rabbitmq-env
-rwxrwxr-x. 1 root root 860 Dec 2 2021 rabbitmq-plugins
-rwxrwxr-x. 1 root root 859 Dec 2 2021 rabbitmq-queues
-rwxrwxr-x. 1 root root 6002 Dec 2 2021 rabbitmq-server
-rwxrwxr-x. 1 root root 857 Dec 2 2021 rabbitmq-streams
-rwxrwxr-x. 1 root root 858 Dec 2 2021 rabbitmq-tanzu
-rwxrwxr-x. 1 root root 860 Dec 2 2021 rabbitmq-upgrade该文件内容如下
I have no name!0d5cb60e3a06:/opt/bitnami/rabbitmq/sbin$ cat rabbitmq-defaults
#!/bin/sh -e

##### next line potentially updated in package install steps
SYS_PREFIX${RABBITMQ_HOME}CLEAN_BOOT_FILEstart_clean
SASL_BOOT_FILEstart_sasl
BOOT_MODULErabbitif test -z $CONF_ENV_FILE test -z $RABBITMQ_CONF_ENV_FILE; thenCONF_ENV_FILE${SYS_PREFIX}/etc/rabbitmq/rabbitmq-env.conf
fi可以看到这个文件有一些变量配置如CONF_ENV_FILE可以大概猜测到是指定rabbitmq的变量配置文件
五、配置文件rabbitmq.conf
配置文件在哪些目录总是让人困扰的一件事最简单的办法就是查看rabbitmq的服务启动日志 本示例通过docker logs 容器名称查看日志
[rootlocalhost ~]# docker logs rabbitmq
......
2023-09-25 04:33:10.21661800:00 [info] 0.222.0 node : rabbitlocalhost
2023-09-25 04:33:10.21661800:00 [info] 0.222.0 home dir : /opt/bitnami/rabbitmq/.rabbitmq
2023-09-25 04:33:10.21661800:00 [info] 0.222.0 config file(s) : /opt/bitnami/rabbitmq/etc/rabbitmq/rabbitmq.conf
2023-09-25 04:33:10.21661800:00 [info] 0.222.0 cookie hash : XvNpT2Nlg8SZCslJcYXN8g
2023-09-25 04:33:10.21661800:00 [info] 0.222.0 log(s) : /opt/bitnami/rabbitmq/var/log/rabbitmq/rabbitlocalhost_upgrade.log
2023-09-25 04:33:10.21661800:00 [info] 0.222.0 : stdout
2023-09-25 04:33:10.21661800:00 [info] 0.222.0 database dir : /bitnami/rabbitmq/mnesia/rabbitlocalhost该文件内容如下 可以看到日志中配置文件在下面的目录 config file(s) : /opt/bitnami/rabbitmq/etc/rabbitmq/rabbitmq.conf
I have no name!0d5cb60e3a06:/opt/bitnami/rabbitmq/etc/rabbitmq$ cat rabbitmq.conf
## Clustering
cluster_partition_handling ignore## Defaults
# During the first start, RabbitMQ will create a vhost and a user
# These config items control what gets created
default_permissions.configure .*
default_permissions.read .*
default_permissions.write .*
default_vhost /
default_user admin
default_pass admin## Networking
listeners.tcp.default 5672## Management
management.tcp.ip 0.0.0.0
management.tcp.port 15672## Resource limits
# Set a free disk space limit relative to total available RAM
disk_free_limit.relative 1.0可以看到rabbitmq监听的端口是5672。一般情况下如果能在rabbitmq-env.conf里面改的数据建议直接在rabbitmq-env.conf里面改。
六、变量生效顺序
环境变量rabbitmq-env.confrabbitmq.conf 以RABBITMQ_NODENAME 这个变量为例
RabbitMQ在启动服务的时候首先判断当前Shell环境中有无 RABBITMQ_NODENANE的定义如果有则启用此值如果没有则查看rabbitmq-env.conf 中是否定义了 NODENAME 这个变量如果有则启用此值如果没有则采用默认的取值规则即 rabbit$HOSTNAME。
附、关于环境变量的说明
