【配置rabbitmq】
配置参考：https://www.rabbitmq.com/install-rpm.html#configuration
配置参考：https://www.rabbitmq.com/configure.html
1.配置允许远程访问：guest -- User can only log in via localhost
# cd /usr/share/doc/rabbitmq-server-3.8.21
# 集群策略文件：set_rabbitmq_policy.sh.example
vim /usr/share/doc/rabbitmq-server-3.8.21/set_rabbitmq_policy.sh.example
注意：
3.8.x版本及以后版本没有rabbitmq.config配置文件，想要解决guest用户远程访问问题，需要自己手动在/etc/rabbitmq/目录下创建rabbitmq.config文件，
? ? ?并添加[{rabbit, [{loopback_users, []}]}]相关配置，详见官方文档(https://www.rabbitmq.com/configure.html)
2.配置新用户
rabbitmqctl add_user admin admin123
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
rabbitmqctl set_user_tags admin administrator
【配置防火墙开放端口】
systemctl stop firewalld
systemctl status firewalld
systemctl restart firewalld
# 查看已经开放端口
# firewall-cmd --list-port
# 检查端口
firewall-cmd --query-port=15672/tcp
# 如果为no，则执行下述命令
firewall-cmd --zone=public --add-port=15672/tcp --permanent
# 重新加载防火墙配置
firewall-cmd --reload
# 重启防火墙
systemctl restart firewalld
【根据需要配置连接符文件句柄数量】
# ulimit -a? ?-- 详见linux相关教程
【启动rabbitmq】
[root@app-server1 escript]# systemctl start rabbitmq-server
# 查看进程启动情况
[root@app-server1 escript]# ps -ef|grep rabbitmq|grep -v grep
