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

sudo gedit /etc/profile

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

java-version看是否已经安装成功了

  
CATALINA_HOME="/usr/local/tomcat"
export JAVA_HOME CATALINA_HOME

$./startup.sh

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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）

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）

}

#/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：  

 error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

解决方法：

ln -s /usr/local/lib/libpcre.so.1 /lib64

32位系统则：

ln -s /usr/local/lib/libpcre.so.1 /lib

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
