Nginx服务器初期基本配置指南

#追加一个www组 
groupadd -f www 
#追加一个nginx用户 
useradd -s /sbin/nologin -g www nginx 

#建立nginx日志目录 
mkdir /var/log/nginx 
#赋予访问权限 
chown nginx.www /var/log/nginx 

./configure --prefix=/opt/servers/nginx \ 
--user=nginx \ 
--group=www \ 
--pid-path=/var/run/nginx.pid \ 
--error-log-path=/var/log/nginx/error.log \ 
--http-log-path=/var/log/nginx/access.log \ 
--with-pcre=/opt/software/pcre-8.10 \ 
--with-zlib=/opt/software/zlib-1.2.5 \ 
--with-http_stub_status_module \ 
--with-http_realip_module \ 
--with-http_gzip_static_module \ 
--without-http_fastcgi_module \ 
--without-http_memcached_module \ 
--without-http_map_module \ 
--without-http_geo_module \
