实践环境：
系统版本：CentOS6.4 X86_64
Nginx版本：Nginx-1.4.5
Tomcat版本：Tomcat-7.0
虚拟机10.10.54.61
############################
源码编译nginx1.4.5
1.下载
[root@gyf soft]#wget http://nginx.org/download/nginx-1.4.5.tar.gz
[root@gyf soft]# tar xvf nginx-1.4.5.tar.gz
2.编译
yum install openssl-devel.X86_64 make pcre
[root@gyf nginx-1.4.5]# ./configure --prefix=/usr/local/nginx --user=apache --group=apache --with-http_stub_status_module --with-http_gzip_static_module --with-http_ssl_module
///
--with-http_stub_status_module enable ngx_http_stub_status_module ---支持监控
--with-http_gzip_static_module enable ngx_http_gzip_static_module ---支持压缩
3.安装
[root@gyf nginx-1.4.5]# make && make install
4.启动
[root@gyf conf]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nginx: [emerg] getpwnam("apache") failed
[root@gyf conf]# useradd apache
[root@gyf conf]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

[root@gyf conf]# apachectl stop
[root@gyf conf]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
5.关闭:给父进程发送一个TERM信号，试图杀死它和它的子进程。
[root@s01 logs]# cat /usr/local/nginx/logs/nginx.pid | xargs kill -TERM
6.重启
[root@s01 logs]# cat /usr/local/nginx/logs/nginx.pid | xargs kill -HUP
HUP 重启
TERM,INT 快速停止
USR1 重新打开日志文件，用于日志切割
USR2 平滑升级可执行程序
QUIT 从容关闭
WINCH 从容关闭工作进程
//测试配置文件
[root@s01 html]# /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf

安装tomcat
1.下载jdk-7u51-linux-x64.rpm
rpm -ivh jdk-7u51-linux-x64.rpm
2.添加环境变量,配置jdk
[root@gyf soft]# find / -name '*jdk*'
/usr/java/jdk1.7.0_51
[root@gyf profile.d]# vim /etc/profile
JAVA_HOME=/usr/java/jdk1.7.0_51
CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib
PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin
export PATH CLASSPATH JAVA_HOME
[root@gyf soft]# source /etc/profile
[root@gyf soft]#java -version
3.安装tomcat
[root@gyf soft]# tar xvf apache-tomcat-7.0.52.tar.gz
[root@gyf soft]# mv apache-tomcat-7.0.52 /usr/local/tomcat
4.做tomcat自动启动脚本
[root@gyf soft]# cd /usr/local/tomcat/bin/
[root@gyf bin]# cp catalina.sh /etc/init.d/tomcat
[root@gyf bin]# chmod +x /etc/init.d/tomcat
[root@gyf init.d]# vim tomcat
#chkconfig: 2345 88 99
#description: tomcat
//jdk目录
:96 JAVA_HOME=/usr/java/jdk1.7.0_51
//tomcat目录
CATALINA_HOME=/usr/local/tomcat
[root@gyf bin]# chkconfig --add tomcat
5.启动tomcat
[root@gyf soft]# /etc/init.d/tomcat start
在浏览器中搜索10.10.54.61：8080出现tomcat原始页面即安装成功
#################
一台机器同时运行两个tomcat
上面前两步无需在做
1.安装tomcat到新目录
[root@gyf soft]# tar xvf apache-tomcat-7.0.52.tar.gz
[root@gyf soft]# mv apache-tomcat-7.0.52 /usr/local/tomcat2
2.编辑tomcat/conf/server.xml,将所有端口号8:开头都改为9开头（其他端口只要不冲突即可，目的是不让多个的Tomcat的端口号冲突）
修改3个地方
第一：
<Server port="9005" shutdown="SHUTDOWN"> ----原来是8005,关闭端口号
第二
<Connector port="9080" maxHttpHeaderSize="8192" ----原来是8080，http链接端口号:1：
第三<Connector port="9009" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" /> ---原来是8009，jvm即java虚拟机访问端口
3.启动
[root@gyf tomcat2]# ./bin/startup.sh
4.查看进程两个
[root@gyf tomcat2]# ps -ef |grep tomcat
7.做tomcat自动启动脚本
[root@gyf soft]# cd /usr/local/tomcat2/bin/
[root@gyf bin]# cp catalina.sh /etc/init.d/tomcat2
[root@gyf bin]# chmod +x /etc/init.d/tomcat2
[root@gyf init.d]# vim tomcat2
#chkconfig: 2345 85 96
#description: tomcat
:96 JAVA_HOME=/usr/java/jdk1.7.0_51
CATALINA_HOME=/usr/local/tomcat2
[root@gyf bin]# chkconfig --add tomcat2
8.重启tomcat2
[root@gyf soft]# /etc/init.d/tomcat2 start
####tomcat配置用户管理
[root@gyf conf]# vim /usr/local/tomcat/conf/tomcat-users.xml
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="tomcat" password="tomcat" roles="admin-gui,manager-gui"/>
##################
配置nginx
1.配置代理文件
[root@gyf htdocs]# cd /usr/local/nginx/conf/
[root@gyf conf]#mkdir virtual
[root@gyf conf]# vim virtual/bbs.ssr.com.conf
upstream bbs_ssr_com {
server localhost:9080 max_fails=3 weight=1 fail_timeout=60s;
server localhost:8080 max_fails=3 weight=3 fail_timeout=60s;
}
server {
listen 80;
server_name bbs.ssr.com;
location / {
#jsp网站程序根目录，一般nginx与tomcat在同一个目录
# root /usr/local/tomcat/webapps/ROOT;
root /var/www/bbs
index index.html index.jsp index.html;
}
location ~ .*\.(gif|jpg|png|bmp|swf)$ #由nginx处理静态页面
{
expires 30d; #使用expires缓存模块，缓存到客户端30天
}
location ~ .*\.(js|css)?$ {
expires 1h;
}
location ~ (\.jsp)|(\.do)$ {
index index.jsp ;
proxy_pass http://bbs_ssr_com; #来自jsp请求交给tomcat处理
proxy_set_header Host $host;
proxy_set_header X-Real-IP$remote_addr;
proxy_set_header X-Forwarded-For$proxy_add_x_forwarded_for;#后端的Web服务器可以通过X-Forwarded-For获取用户真实IP
proxy_redirect off;
client_max_body_size 10m; #允许客户端请求的最大单文件字节数
client_body_buffer_size 128k; #缓冲区代理缓冲用户端请求的最大字节数，
proxy_connect_timeout 90; #nginx跟后端服务器连接超时时间(代理连接超时)
proxy_read_timeout 90; #连接成功后，后端服务器响应时间(代理接收超时)
proxy_buffer_size 4k; #设置代理服务器（nginx）保存用户头信息的缓冲区大小
proxy_buffers 6 32k; #proxy_buffers缓冲区，网页平均在32k以下的话，这样设置
proxy_busy_buffers_size 64k; #高负荷下缓冲大小（proxy_buffers*2）
proxy_temp_file_write_size 64k; #设定缓存文件夹大小，大于这个值，将从upstream服务器传
}
}
2..主配置文件配置
[root@gyf ~]# vi /usr/local/nginx/conf/nginx.conf
user nginx nginx;
worker_processes 2;
error_log logs/error.log info;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#日志格式定义
log_format main ‘$remote_addr – $remote_user[$time_local] “$request” ‘
‘$status $body_bytes_sent”$http_referer” ‘
‘”$http_user_agent” “$http_x_forwarded_for”‘;
access_log logs/access.log main;
sendfile on;
keepalive_timeout 65;
#gzip压缩功能设置
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-javascripttext/css application/xml;
gzip_vary on;
include virtual/bbs.ssr.com.conf;
}
3.配置tomcat
[root@gyf conf]# vim /usr/local/tomcat/conf/server.xml
#确认8080端口
:70 <Connector port="8080" protocol="HTTP/1.1"
71 connectionTimeout="20000"
72 redirectPort="8443" />
123 <Host name="localhost" appBase="webapps"
124 unpackWARs="true" autoDeploy="true">
<Context path="" docBase="/var/www/bbs" />
125 如果网站没有放在tomcat默认根目录/usr/local/tomcat/webapps/ROOT/
时添加<Context path="" docBase="/var/www/bbs" />
[root@gyf conf]# vim /usr/local/tomcat2/conf/server.xml
#确认9080端口
:70 <Connector port="8080" protocol="HTTP/1.1"
71 connectionTimeout="20000"
72 redirectPort="8443" />
123 <Host name="localhost" appBase="webapps"
124 unpackWARs="true" autoDeploy="true">
<Context path="" docBase="/var/www/bbs" />
4.建网页
[root@gyf www]#mkdir -p /var/www/bbs
[root@gyf bbs]# vim index.html
html
[root@gyf bbs]# vim index.jsp
jsp
[root@gyf bbs]# vim index.do
do
5.重启服务
[root@gyf ~]# /etc/init.d/nginx restart
[root@gyf ~]# /etc/init.d/tomcat restart
[root@gyf ~]# /etc/init.d/tomcat2 restart
6.测试
在ubuntu10.10.54.60
gyf@gyf :~$ vim /etc/hosts
10.10.54.60 bbs.ssr.com
在搜索应请输入bbs.ssr.com
显示html
输入bbs.ssr.com/index.jsp
http://10.10.54.61/index.jsp
显示jsp
输入bbs.ssr.com/index.do
http://10.10.54.61/index.do
显示do
