ubuntu 12.04下編譯安裝nginx-1.9.3之後 tomcat叢集
一、tomcat安裝
1.安裝nginx 請檢視http://blog.csdn.net/liangzi4454/article/details/47023447
2. jdk安裝不在贅述，不會的同學，可以網上查詢教程；
3. tomcat下載
本人tomcat版本為 tomcat-6.0.44，請自行到官網下載對應的版本或是在終端輸入 wget http://mirrors.cnnic.cn/apache/tomcat/tomcat-6/v6.0.44/bin/apache-tomcat-6.0.44.tar.gz 下載。
4.tomcat安裝
建立/usr/local/tomcat-6.0.44_1和/usr/local/tomcat-6.0.44_2目錄，並將tomcat解壓兩份到這兩個目錄中。
5.修改/usr/local/tomcat-6.0.44_2/conf/server.xml 中的三個埠8005為8015，8080為8090，8009為8019。
6.在以上兩個tomcat目錄的webapps下建立ROOT/a/index.jsp，啟動tomcat ，瀏覽器輸入http://localhost:8080/a/index.jsp和http://localhost:8090/a/index.jsp 見到index頁面，說明安裝成功。
6.增加tomcat記憶體
開啟/bin/catalina.sh 頂部加入JAVA_OPTS="-server -Xms800m -Xmx800m -XX:PermSize=64M -XX:MaxNewSize=256m -XX:MaxPermSize=128m -Djava.awt.headless=true"
二、nginx與單個tomcat叢集
1. 在/usr/local/nginx/conf/目錄下建立proxy.conf檔案，加入內容儲存退出:
#!nginx (-)
# proxy.conf
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr; #獲取真實ip
# proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; #獲取代理者的真實ip
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
2.在根目錄下建立/home/www/root1/ROOT和/home/www/root1/ROOT目錄，並將剛才tomcat中建立的index.jsp放到該目錄下
3.修改兩個tomcat的server.xml如下，將第2不建立的兩個目錄加入到appBase中：
<Host name="localhost" appBase="/home/www/root1"
xmlValidation="false" xmlNamespaceAware="false">
4.開啟/usr/local/nginx/nginx.conf 檔案，修改內容並退出：
# 執行nginx所在的使用者名稱和使用者組
user nginx nginx; #新增
#user nobody;
worker_processes 1;
# 全域性錯誤日誌及PID檔案
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
error_log /usr/local/nginx/logs/error.log; #新增
# pid logs/nginx.pid;
pid /usr/local/nginx/nginx.pid; #新增
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
# 全域性訪問日誌
#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 網站根目錄
#charset koi8-r;
access_log /usr/local/nginx/logs/host.access.log; #新增
#access_log logs/host.access.log main;
location / {
# 下邊兩行暫時注掉
# root html;
# index index.html index.htm;
# 新增 將index.jsp 加入到預設的訪問首頁地址
index index.html index.htm index.jsp;
#轉向tomcat處理
proxy_pass http://localhost:8080;
}
#新增 所有jsp的頁面均交由tomcat處理
location ~ .*.jsp$ {
index index.jsp;
proxy_pass http://localhost:8080;
}
#新增 設定訪問靜態檔案直接讀取不經過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.測試nginx配置
終端執行如下命令:
/usr/local/nginx/sbin/nginx-t
出現如下資訊表示失敗:
nginx: [emerg] getpwnam("nginx") failed in /usr/local/nginx/conf/nginx.conf:2
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed
解決辦法: 新增使用者組
終端執行如下命令：
sudo adduser --system --no-create-home --disabled-password --group nginx
再次測試nginx 出現如下資訊表示成功:
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.啟動nginx後啟動tomcat
終端執行如下兩條命令:
/etc/init.d/nginx start
/usr/local/tomcat-6.0.44_1/bin/catalina.sh start
7. 測試
瀏覽器中輸入http://localhost:8080看到index.jsp資訊表示nginx和單個tomcat叢集建立成功
三、建立nginx和多個tomcat叢集
未完待續。。。
