ubuntu 12.04下编译安装nginx-1.9.3之后 tomcat集群

一、tomcat安装

1.安装nginx 请查看http://blog.csdn.net/liangzi4454/article/details/47023447

2. jdk安装不在赘述，不会的同学，可以网上查找教程；

3. tomcat下载

本人tomcat版本为 tomcat-6.0.44，请自行到官网下载对应的版本或是在终端输入 wget http://mirrors.cnnic.cn/apache/tomcat/tomcat-6/v6.0.44/bin/apache-tomcat-6.0.44.tar.gz 下载。

4.tomcat安装

创建/usr/local/tomcat-6.0.44_1和/usr/local/tomcat-6.0.44_2目录，并将tomcat解压两份到这两个目录中。

5.修改/usr/local/tomcat-6.0.44_2/conf/server.xml 中的三个端口8005为8015，8080为8090，8009为8019。

6.在以上两个tomcat目录的webapps下创建ROOT/a/index.jsp，启动tomcat ，浏览器输入http://localhost:8080/a/index.jsp和http://localhost:8090/a/index.jsp 见到index页面，说明安装成功。

6.增加tomcat内存

打开/bin/catalina.sh 顶部加入JAVA_OPTS="-server -Xms800m -Xmx800m -XX:PermSize=64M -XX:MaxNewSize=256m -XX:MaxPermSize=128m -Djava.awt.headless=true"

二、nginx与单个tomcat集群

1. 在/usr/local/nginx/conf/目录下创建proxy.conf文件，加入内容保存退出:

#!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;

2.在根目录下创建/home/www/root1/ROOT和/home/www/root1/ROOT目录，并将刚才tomcat中创建的index.jsp放到该目录下

3.修改两个tomcat的server.xml如下，将第2不创建的两个目录加入到appBase中：

<Host name="localhost" appBase="/home/www/root1"

xmlValidation="false" xmlNamespaceAware="false">

4.打开/usr/local/nginx/nginx.conf 文件，修改内容并退出：

# 运行nginx所在的用户名和用户组

user nginx nginx; #新增

#user nobody;

worker_processes 1;

# 全局错误日志及PID文件

#error_log logs/error.log;

#error_log logs/error.log notice;

#error_log logs/error.log info;

error_log /usr/local/nginx/logs/error.log; #新增

# pid logs/nginx.pid;

pid /usr/local/nginx/nginx.pid; #新增

events {

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

#log_format main '$remote_addr - $remote_user [$time_local] "$request" '

# '$status $body_bytes_sent "$http_referer" '

# '"$http_user_agent" "$http_x_forwarded_for"';

# 全局访问日志

#access_log logs/access.log main;

access_log /usr/local/nginx/logs/access.log; #新增

sendfile on;

#tcp_nopush on;

#keepalive_timeout 0;

keepalive_timeout 65;

#gzip on;

server {

listen 80;

server_name localhost;

root /home/www/root1/ROOT; #新增 网站根目录

#charset koi8-r;

access_log /usr/local/nginx/logs/host.access.log; #新增

#access_log logs/host.access.log main;

location / {

# 下边两行暂时注掉

# root html;

# index index.html index.htm;

# 新增 将index.jsp 加入到默认的访问首页地址

index index.html index.htm index.jsp;

#转向tomcat处理

proxy_pass http://localhost:8080;
}

#新增 所有jsp的页面均交由tomcat处理

location ~ .*.jsp$ {

index index.jsp;

proxy_pass http://localhost:8080;
}

#新增 设定访问静态文件直接读取不经过tomcat

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ {

expires 30d;

}

#新增

location ~ .*\.(js|css)?$ {

expires 1h;

}

#error_page 404 /404.html;

# redirect server error pages to the static page /50x.html

#

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root html;

}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

#

#location ~ \.php$ {

# proxy_pass http://127.0.0.1;
#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

#

#location ~ \.php$ {

# root html;

# fastcgi_pass 127.0.0.1:9000;

# fastcgi_index index.php;

# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;

# include fastcgi_params;

#}

# deny access to .htaccess files, if Apache's document root

# concurs with nginx's one

#

#location ~ /\.ht {

# deny all;

#}

}

# another virtual host using mix of IP-, name-, and port-based configuration

#

#server {

# listen 8000;

# listen somename:8080;

# server_name somename alias another.alias;

# location / {

# root html;

# index index.html index.htm;

# }

#}

# HTTPS server

#

#server {

# listen 443 ssl;

# server_name localhost;

# ssl_certificate cert.pem;

# ssl_certificate_key cert.key;

# ssl_session_cache shared:SSL:1m;

# ssl_session_timeout 5m;

# ssl_ciphers HIGH:!aNULL:!MD5;

# ssl_prefer_server_ciphers on;

# location / {

# root html;

# index index.html index.htm;

# }

#}

}

5.测试nginx配置

终端执行如下命令:

/usr/local/nginx/sbin/nginx-t

出现如下信息表示失败:

nginx: [emerg] getpwnam("nginx") failed in /usr/local/nginx/conf/nginx.conf:2

nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed

解决办法: 添加用户组

终端执行如下命令：

sudo adduser --system --no-create-home --disabled-password --group nginx

再次测试nginx 出现如下信息表示成功:

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

6.启动nginx后启动tomcat

终端执行如下两条命令:

/etc/init.d/nginx start

/usr/local/tomcat-6.0.44_1/bin/catalina.sh start

7. 测试

浏览器中输入http://localhost:8080看到index.jsp信息表示nginx和单个tomcat集群建立成功

三、建立nginx和多个tomcat集群
