CentOS8的基础防火墙配置

发表评论

systemctl使用
systemctl unmask firewalld #执行命令，即可实现取消服务的锁定
systemctl mask firewalld # 下次需要锁定该服务时执行
systemctl start firewalld.service #启动防火墙
systemctl stop firewalld.service #停止防火墙
systemctl reloadt firewalld.service #重载配置
systemctl restart firewalld.service #重启服务
systemctl status firewalld.service #显示服务的状态
systemctl enable firewalld.service #在开机时启用服务
systemctl disable firewalld.service #在开机时禁用服务
systemctl is-enabled firewalld.service #查看服务是否开机启动
systemctl list-unit-files|grep enabled #查看已启动的服务列表
systemctl –failed #查看启动失败的服务列表

firewall-cmd使用
firewall-cmd –state #查看防火墙状态
firewall-cmd –reload #更新防火墙规则
firewall-cmd –state #查看防火墙状态
firewall-cmd –reload #重载防火墙规则
firewall-cmd –list-ports #查看所有打开的端口
firewall-cmd –list-services #查看所有允许的服务
firewall-cmd –get-services #获取所有支持的服务

/usr/lib/firewalld/services

#区域相关
firewall-cmd –list-all-zones #查看所有区域信息
firewall-cmd –get-active-zones #查看活动区域信息
firewall-cmd –set-default-zone=public #设置public为默认区域
firewall-cmd –get-default-zone #查看默认区域信息
firewall-cmd –zone=public –add-interface=eth0 #将接口eth0加入区域public
#接口相关
firewall-cmd –zone=public –remove-interface=eth0 #从区域public中删除接口eth0
firewall-cmd –zone=default –change-interface=eth0 #修改接口eth0所属区域为default
firewall-cmd –get-zone-of-interface=eth0 #查看接口eth0所属区域

用例
firewall-cmd –query-port=8080/tcp # 查询端口是否开放

firewall-cmd –add-port=80/tcp –permanent #永久添加80端口例外(全局)
firewall-cmd –remove-port=80/tcp –permanent #永久删除80端口例外(全局)
firewall-cmd –add-port=65001-65010/tcp –permanent #永久增加65001-65010例外(全局)
firewall-cmd –zone=public –add-port=80/tcp –permanent #永久添加80端口例外(区域public)
firewall-cmd –zone=public –remove-port=80/tcp –permanent #永久删除80端口例外(区域public)
firewall-cmd –zone=public –add-port=65001-65010/tcp –permanent #永久增加65001-65010例外(区域public)

firewall-cmd –reload #重启防火墙(修改配置后要重启防火墙)

nginx+v2ray

参照这个文章的配置，

https://www.ecsoe.com/archives/38.html

一次成功

先安装了nginx+ssl，再安装v2ray，调整配置。

yum -y update
bash <(curl -L -s https://install.direct/go.sh)
systemctl enable v2ray
vi /etc/nginx/conf.d/v2ray.conf

server {
    listen       443 ssl;

    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
    ssl_prefer_server_ciphers on;
    ssl_session_cache shared:SSL:10m;
    ssl_session_timeout 10m;
    error_page 497  https://$host$request_uri;

    proxy_redirect             off;

    proxy_set_header Upgrade   $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host      $http_host;
    }
}

      },

yii 邮件发送问题解决

发表评论

yii邮件发送，一直报错

Swift_TransportException
Expected response code 250 but got code “550”, with message “550 5.7.1 Request not taken sender domain mismatch !
”

其实说的比较清楚了。是Request not taken sender domain mismatch

但是web.php已经修改了，找了半天，发现

config\params.php

下面的adminEmail也要修改成一致的才行。

如何让外网访问小米路由器的硬盘文件

发表评论

解决只能lan口访问，不能wan口访问硬盘资源的问题。

1、小米路由器要开启ssh
2、ssh到小米路由器，编辑/etc/samba/smb.conf.template 文件，将其中的interfaces那一行改为

interfaces = br-lan eth0.2

3、编辑/etc/config/firewall文件，在文件最后添加以下内容：

config rule 'samba_udp'                                
        option src 'wan'                    
        option dest_port '137 138'             
        option proto 'udp'                                  
        option target 'ACCEPT'                  
        option name 'samba_incoming_udp'

config rule 'samba_tcp'        
        option src 'wan'                                   
        option dest_port '139 445'            
        option proto 'tcp'                
        option target 'ACCEPT'                 
        option name 'samba_incoming_tcp'

4、执行/etc/init.d/samba restart命令重启samba服务
5、执行/etc/init.d/firewall restart命令重启防火墙

用\\xxx.xxx.xxx.xxx 访问试试。xxx是小米路由器的wan ip地址

nginx日志按天切割的脚本

发表评论

本脚本原版来自 lnmp.org,修改如下：
不需要写每个日志文件，除了error日志，其他的都自动切割
不按照年月分目录，放在一个目录，这样好处理点。
用法就是放在服务器上 chmod +x，然后加到crontab里

cat /root/bin/cut_nginx_logs.sh
#!/bin/bash
#function:cut nginx log files for lnmp
#author: http://lnmp.org
