nginx+tomcat动静态资源分离

1 创建用户、用户组

useradd -g users www

passwd www //设置密码，否则该用户不可用

groupadd -g 888 www //创建用户组

gpasswd -a www www //将用户www加入用户组www

2 下载nginx、pcre(正则使用)

wget http://blog.s135.com/soft/linux/nginx_php/nginx/nginx-0.8.46.tar.gz

wget http://blog.s135.com/soft/linux/nginx_php/pcre/pcre-8.10.tar.gz

3 安装pcre

tar zxvf pcre-8.10.tar.gz

cd pcre-8.10/

./configure

make

make install

4 安装nginx

tar zxvf nginx-0.8.46.tar.gz

cd nginx-0.8.46/

./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module -- with-http_ssl_module

make

make install

5 nginx.conf配置

6 启动nginx

1. 重新运行一下/usr/local/nginx/sbin/nginx
2. 重启nginx：/usr/local/nginx/sbin/nginx -s reload

7 停止nginx

1：查询nginx主进程号
ps -ef | grep nginx
在进程列表里 面找master进程，它的编号就是主进程号了。
2：发送信号
从容停止Nginx：
kill -QUIT 主进程号
快速停止Nginx：
kill -TERM 主进程号
强制停止Nginx：
pkill -9 nginx
