问题解决: 首次启动nginx报错 nginx: [error] open() "/var/run/nginx.pid" failed (2: No such file or directory)

首次启动nginx报错 nginx: [error] open() “/var/run/nginx.pid” failed (2: No such file or directory)

背景

• 阿里云服务器CentOS 7, 比较新 干净!

• 严格按照官网安装Nginx, 但首次启动报错 nginx: [error] open() “/var/run/nginx.pid” failed (2: No such file or directory)

解决

1. 修改核心配置文件中pid的值为: /etc/nginx/logs/nginx.pid

   vim /etc/nginx/nginx.conf;
   

   要分号结尾, 否则报错信息也能指向这个错误!

   去/etc/nginx/中新建logs文件夹

2. 进入conf.d, 并执行命令

   cd /etc/nginx/conf.d
   

   /usr/sbin/nginx -c /etc/nginx/nginx.conf
   

   但是会报错

   nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
   nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
   nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
   nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
   nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
   nginx: [emerg] still could not bind()
   

3. 强杀80端口

   sudo fuser -k 80/tcp
   

   再次运行3中-c命令, 解决!

小结

• https://www.jianshu.com/p/efa0968eb581资料对我帮助很大, 但是需要注意要认真适配自己具体的情况!

• 误打误撞, 拼拼凑凑, 必须记下来, 因为能感觉到下次还能顺利解决的概率太低!!!
