在Centos+nginx+wordpress环境下启动iptables 网站返回502

Jun 23, 2016 pm 02:23 PM

iptables nginx fastCGI

网站环境:Centos nginx php(wordpress)

现在的问题总结如下:
启动iptables网站返回502,关闭iptables网站打开正常

iptables 设置如下:
Chain INPUT (policy DROP 1 packets, 139 bytes)
 pkts bytes target     prot opt in     out     source               destination         
    0     0 ACCEPT     all  --  lo     any     anywhere             anywhere            
   17  1460 ACCEPT     all  --  any    any     anywhere             anywhere            state RELATED,ESTABLISHED 
    1    40 ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp dpt:ssh 
    0     0 ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp dpt:mysql 
    2    80 ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp dpt:http 
    0     0 ACCEPT     all  --  lo     any     anywhere             anywhere

    0     0 ACCEPT     gre  --  any    any     anywhere             anywhere            

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain OUTPUT (policy ACCEPT 16 packets, 4024 bytes)
 pkts bytes target     prot opt in     out     source               destination         
    2    80 ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp spt:http 

开启了lo,开启了80,开始了9000

在开启iptables时,静态的网页时能打开的,但是切换回wordpress是又返回502.

查看error-log都是:
2013/09/26 01:45:37 [error] 1745#0: *106 recv() failed (104: Connection reset by peer) while reading response header from upstream, client:, server: xiaobuxun.me, request: "POST /wp-admin/admin-ajax.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xiaobuxun.me", referrer: "http://xiaobuxun.me/wp-admin/post-new.php"

我考虑是iptables的问题,是fastCGI用的9000端口没有打开,,但是我已经配置上了,为什么还是返回502,求大神指教了!!!

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
