说正事儿,先说下我的想法,
前端负载均衡服务器采用Nginx,
中间配置两个(或多个)apache+tomcat
应用程序服务器,
后端采用连接到一个数据库,
采用共享磁盘的方式公用一个文件服务器,
配置nginx开始:
1、下载 pcre、nginx、openssl 程序包,
我这里用的分别是
pcre-8.00.tar.gz、
nginx-0.7.51.tar.gz、
openssl-1.0.0-beta3.tar.tar,
2、安装程序
安装openssl 程序,解压缩,./config
make && make install
groupadd www
useradd -g www www
tar zxvf pcre-8.00.tar.gz
cd pcre-8.00
./configure
make && make install
tar zxvf nginx-0.7.51.tar.gz
cd nginx-0.7.51
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install
这样就安装完毕了
3、启动
执行 # /usr/local/webserver/nginx/sbin/nginx 命令启动程序
[root@localhost nginx-0.7.51]# ps -ef |grep nginx (查看命令)
root 4276 1 0 00:23 ? 00:00:00 nginx: master process /usr/local/webserver/nginx/sbin/nginx
www 4277 4276 0 00:23 ? 00:00:00 nginx: worker process
4276为nginx主程序,可以看到程序运行起来了。
访问web页面,http://localhost ,可以看见 “
”字样,说明程序运行良好。
4、变http 为https
修改配置文件
# vi /usr/local/webserver/nginx/conf/nginx.conf
把 http {}括号里面的 第一个server配置全部注释掉
##########
#server {
#listen 443;
#server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
# # location / {
# # root html;
index index.html index.htm;
## }
#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;
#}
# }
############################
把第三个server,https sever 的注释去掉并改为
#####################
# HTTPS server
#
server {
listen 443;
server_name localhost;
ssl on;
ssl_certificate server.crt;
ssl_certificate_key server.key;
ssl_session_timeout 5m;
ssl_protocols SSLv2 SSLv3 TLSv1;
ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
ssl_prefer_server_ciphers on;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
##########################
这里面需要两个 证书文件,即红色的部分,
方法如下:
To generate private (dummy) certificates you can perform the following list of openssl commands.
First change directory to where you want to create the certificate and private key, for example:
$ cd /usr/local/nginx/conf
Now create the server private key, you'll be asked for a passphrase:
$ openssl genrsa -des3 -out server.key 1024
Create the Certificate Signing Request (CSR):
$ openssl req -new -key server.key -out server.csr
Remove the necessity of entering a passphrase for starting up nginx with SSL using the above private key:
$ cp server.key server.key.org $ openssl rsa -in server.key.org -out server.key
Finally sign the certificate using the above private key and CSR:
$ openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
,然后把生成的 server.crt 和 server.key 放到和nginx.conf 同一个文件夹下
执行 # /usr/local/webserver/nginx/sbin/nginx -t 查看修改的配置文件是否正确,正确的信息如下
2010/11/27 01:00:33 [info] 4383#0: the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
2010/11/27 01:00:33 [info] 4383#0: the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully
如果不正确,按照提示修改正确。
重启nginx
操作如下:
[root@localhost conf]# ps -ef |grep nginx
root 4276 1 0 00:23 ? 00:00:00 nginx: master process /usr/local/webserver/nginx/sbin/nginx
www 4371 4276 0 00:51 ? 00:00:00 nginx: worker process
root 4389 3998 0 01:01 pts/1 00:00:00 grep nginx
[root@localhost conf]# kill -HUP 4276
然后访问页面,https://localhost ,出现 “
”字体,说明 ssl 配置正确
5、配置后端 apache
配置文件修改如下,可以参考,不必一样,重点注意红色部分

然后重新启动 nginx,访问 https://localhost,
在我这个配置里面,就会把请求发送到 10.1.3.247 或 10.2.2.137上。
如果是对session有要求的程序,需要实现session共享的,那么你可以把 ip_hash的注释去掉,就可以正常访问了。
