首先是安装包的准备nginx7.9:下载nginx |tomcat7.0下载tomcat |JDk下载JDK7.0
Nginx的优点太多太多，比apache好很多，更加稳定，功能更加强悍，越来越多的开发人员选择使用nginx来替代apache！！
具体查看这篇文章http://blog.csdn.net/a454211787/article/details/22494485
首先，我们配置jdk,下载好jdk之后,我的默认实在download下面，然后使用linux命令解压
$tar zxvf jdk安装完(我是安装在/usr/java)之后，输入linux命令
sudo gedit /etc/profile编辑profile文件，添加以下文本
export JAVA_HOME=/usr/java/jdk1.6.0_27 export JAVA_BIN=/usr/java/jdk1.6.0_27/bin export PATH=$PATH:$JAVA_HOME/bin export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export JAVA_HOME JAVA_BIN PATH CLASSPATH运行
java-version看是否已经安装成功了接着安装tomcat,并且重命名为tomcat,编辑/etc/frofile加上以下语句
CATALINA_HOME="/usr/local/tomcat" export JAVA_HOME CATALINA_HOME
$./startup.sh然后访问http://localhost:8080看是否访问成功.如果看到了tomcat的欢迎界面，恭喜你已经成功了一半,

接下来我们安装nginx,我们解压nginx
$tar zxvf nginx~~~.tar.gz然后 $cd nginx/
$./configure
$make
$sudo make install（记住这里要用超级权限）当执行./configure的时候会抛出说缺少PCRE library 这个是HTTP Rewrite 模块，也即是url静态化的包
所以首先我们要安装这个东西 PCRE下载pcre选择7.9版本
$tar zxvf pcre~~.tar.gz $./configure $make $sudo make install
接下来我们执行以下命令，在nginx的conf文件夹下面创建一个proxy.conf文件，配置一些代理参数
$cd /usr/local/nginx/conf $sudo touch proxy.conf
#!nginx (-) # proxy.conf proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; #获取真实ip #proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; #获取代理者的真实ip client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k;
$sudo gedit nginx.conf（记住要是超级权限）写上基本配置
#运行nginx所在的用户名和用户组
#user www www;
#启动进程数
worker_processes 8;
#全局错误日志及PID文件
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
#工作模式及连接数上限
events
{
use epoll;
worker_connections 65535;
}
#设定http服务器，利用它的反向代理功能提供负载均衡支持
http
{
#设定mime类型
include mime.types;
default_type application/octet-stream;
include /usr/local/nginx/conf/proxy.conf;
#charset gb2312;
#设定请求缓冲
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 8m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
# fastcgi_connect_timeout 300;
# fastcgi_send_timeout 300;
# fastcgi_read_timeout 300;
# fastcgi_buffer_size 64k;
# fastcgi_buffers 4 64k;
# fastcgi_busy_buffers_size 128k;
# fastcgi_temp_file_write_size 128k;
# gzip on;
# gzip_min_length 1k;
# gzip_buffers 4 16k;
# gzip_http_version 1.0;
# gzip_comp_level 2;
# gzip_types text/plain application/x-javascript text/css application/xml;
# gzip_vary on;
#limit_zone crawler $binary_remote_addr 10m;
###禁止通过ip访问站点
server{
server_name _;
return 404;
}
server
{
listen 80;
server_name localhost;
index index.html index.htm index.jsp;#设定访问的默认首页地址
root /home/www/web/ROOT;#设定网站的资源存放路径
#limit_conn crawler 20;
location ~ .*.jsp$ #所有jsp的页面均交由tomcat处理
{
index index.jsp;
proxy_pass http://localhost:8080;#转向tomcat处理
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ #设定访问静态文件直接读取不经过tomcat
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 1h;
}
#定义访问日志的写入格式
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log /usr/local/nginx/logs/localhost.log access;#设定访问日志的存放路径
}
}然后我们运行linux命令#/usr/local/nginx/sbin/nginx -t
如果屏幕显示以下两行信息，说明配置文件正确：
the configuration file /usr/local/nginx/conf/nginx.conf syntax is okthe configuration file /usr/local/nginx/conf/nginx.conf was tested successfull
error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
解决方法：
32位系统则：
注：
/usr/local/lib/libpcre.so.1 为prce安装后的文件地址
低版本prce对应的libpcre.so.1 为libpcre.so.0
#/usr/local/nginx/sbin/nginx
#/usr/local/nginx/sbin/nginx -s stop
检查nginx配置是否正确</span>
/usr/local/nginx/sbin/nginx -t
查看nginx进程
ps -ef |grep nginx
