linux下Nginx+tomcat整合的安装与配置
目的:搭建Nginx与tomcat整合,用Nginx代替apache
步骤:
一、安装Tomcat和JDK
1、上传apache-tomcat-6.0.18.tar.gz和jdk-6u12-linux-i586.bin至/usr/local
2、执行如下命令安装tomcat:
#cd /usr/local
#tar zxvf apache-tomcat-6.0.18.tar.gz
解压完成后将apache-tomcat-6.0.18重命名为tomcat
3、执行如下命令安装JDK:
#./jdk-6u12-linux-i586.bin
4、配置环境变量:
编辑/etc下的profile文件,加上如下内容:
JAVA_HOME="/usr/local/jdk1.6.0_12"
CLASS_PATH="$JAVA_HOME/lib:$JAVA_HOME/jre/lib"
PATH=".:$PATH:$JAVA_HOME/bin "
CATALINA_HOME="/usr/local/tomcat"
export JAVA_HOME CATALINA_HOME
5、启动tomcat并输入http://localhost:8080,如果看到猫的页面即tomcat和jdk安装成功
6、新建文件目录/home/www为网站存放目录,设置server.xml文件,在Host name="localhost"处将appBase=的指向路径改为/home/www/web
7、创建index.jsp至/home/www/web/ROOT,内容为:“My web!”
二、安装Nginx
1、上传nginx-0.7.63.tar.gz至/usr/local
2、执行如下命令解压nginx:
#cd /usr/local
#tar zxvf nginx-0.7.63.tar.gz
3、编译安装nginx
#cd nginx-0.7.63
#./configure --with-http_stub_status_module --with-http_ssl_module #启动server状态页和https模块
执行完后会提示一个错误,说缺少PCRE library 这个是HTTP Rewrite 模块,也即是url静态化的包
可上传pcre-7.9.tar.gz,输入如下命令安装:
#tar zxvf pcre-7.9.tar.gz
#cd pcre-7.9
#./configure
#make
#make install
安装pcre成功后,继续安装nginx
#cd nginx-0.7.63
#./configure
#make
#make install
4、nginx安装成功后的安装目录为/usr/local/nginx
在conf文件夹中新建proxy.conf,用于配置一些代理参数,内容如下:
#!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;
编辑安装目录下conf文件夹中的nginx.conf,输入如下内容
#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;
