安装和配置nginx

<pre name="code" class="sql">web服务器nginx和apache的对比分析

yum -y install  gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml* ncurses* libmcrypt* 

配置nginx
 ./configure --prefix=/usr/local/nginx --with-http_stub_status_module

解释： --prefix 为安装路径，--with-为需要安装的模块，具体可以运行./configure --help 查看有效模块

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option

yum -y install  *pcre*

make

make install

启用:

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

1.demo:/etc/nginx# /usr/local/nginx/sbin/nginx -c /etc/nginx/nginx.conf 
nginx: [emerg] getpwnam("nginx") failed in /etc/nginx/nginx.conf:2

解决:创建nginx用户和组

jrhwpt01:/etc# id nginx
uid=411(nginx) gid=411(nginx) groups=411(nginx)

front-end:/root/nginx-1.7.7# useradd -m -g nginx -s /sbin/nologin  nginx

2.demo:/etc/nginx# /usr/local/nginx/sbin/nginx -c /etc/nginx/nginx.conf 
nginx: [emerg] open() "/etc/nginx/mime.types" failed (2: No such file or directory) in /etc/nginx/nginx.conf:16

文件路径不对:
demo:/usr/local/nginx# cd conf/
demo:/usr/local/nginx/conf# ls
fastcgi.conf          fastcgi_params          koi-utf  mime.types          nginx.conf          scgi_params          uwsgi_params          win-utf

demo:/usr/local/nginx/conf# cp -r * /etc/nginx/
cp: overwrite `/etc/nginx/nginx.conf'? y


demo:/etc/nginx# /usr/local/nginx/sbin/nginx -c /etc/nginx/nginx.conf

启动正常

1.修改权限:
demo:/var/www# chmod -R 777 zjzc-web-frontEnd

http://192.168.32.172:8001/ --正常访问


demo:/var/www# ps -ef | grep nginx
