這時(shí)才發(fā)現(xiàn)上面的--prefix配置錯誤， 必須用絕對路徑，不能用形如~符號

卸載重裝Nginx的正確姿勢

ganiks ?  nginx-1.8.0  ./configure --prefix=/home/ganiks/learn/nginx/Nginx

  nginx path prefix: "/home/ganiks/learn/nginx/Nginx"

ganiks ?  Nginx  pwd
/home/ganiks/learn/nginx/Nginx

  
查看當(dāng)前Nginx版本版本信息

ganiks ?  Nginx  ./sbin/nginx -V
nginx version: nginx/1.8.0
built by gcc 4.8.2 (Ubuntu 4.8.2-19ubuntu1)
configure arguments: --prefix=/home/ganiks/learn/nginx/Nginx

ganiks ?  Nginx  ./sbin/nginx -V 2>&1 > some_file

  
這里要重定向才可以輸出到文件哦

ganiks ?  Nginx  ./sbin/nginx -p .
nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied)
ganiks ?  Nginx  vim conf/nginx.conf && listen 8765
ganiks ?  Nginx  ./sbin/nginx -p .  
ganiks ?  Nginx  sudo ps -ef | grep nginx             
ganiks   21174     1  0 15:32 ?        00:00:00 nginx: master process ./sbin/nginx -p .
ganiks   21175 21174  0 15:32 ?        00:00:00 nginx: worker process
ganiks   21182 20842  0 15:32 pts/4    00:00:00 grep nginx


ganiks ?  Nginx  ./sbin/nginx -t
nginx: the configuration file /home/ganiks/learn/nginx/Nginx/conf/nginx.conf syntax is ok
nginx: configuration file /home/ganiks/learn/nginx/Nginx/conf/nginx.conf test is successful
ganiks ?  Nginx  ./sbin/nginx -s reload
ganiks ?  Nginx  sudo ps -ef | grep nginx
ganiks   21174     1  0 15:32 ?        00:00:00 nginx: master process ./sbin/nginx -p .
ganiks   21290 21174  0 15:35 ?        00:00:00 nginx: worker process
ganiks   21294 20842  0 15:35 pts/4    00:00:00 grep nginx
ganiks ?  Nginx  ./sbin/nginx -s reload   
ganiks ?  Nginx  sudo ps -ef | grep nginx 
ganiks   21174     1  0 15:32 ?        00:00:00 nginx: master process ./sbin/nginx -p .
ganiks   21308 21174  0 15:35 ?        00:00:00 nginx: worker process
ganiks   21313 20842  0 15:35 pts/4    00:00:00 grep nginx

  
nginx reload 之后， worker 進(jìn)程是重新創(chuàng)建了的

ganiks ?  Nginx  cat logs/nginx.pid
21174

  
nginx.pid 里面保存的是nginx的主進(jìn)程號
