MAKE && MAKE INSTALL

ganiks ➜  nginx-1.8.0  make && sudo make install

这时才发现上面的--prefix配置错误， 必须用绝对路径，不能用形如~符号

MAKE CLEAN

ganiks ➜  nginx-1.8.0  sudo rm -rf \~
ganiks ➜  nginx-1.8.0  make clean

卸载重装Nginx的正确姿势

CONFIGURE && INSTALL AGAIN

VERSION

查看当前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

这里要重定向才可以输出到文件哦

START NGINX

ganiks ➜  Nginx  ./sbin/nginx -p .

ganiks ➜  Nginx  vim conf/nginx.conf && listen 8765

ganiks   21313 20842  0 15:35 pts/4    00:00:00 grep nginx

nginx reload 之后， worker 进程是重新创建了的

ganiks ➜  Nginx  cat logs/nginx.pid
21174

nginx.pid 里面保存的是nginx的主进程号
