  三、相关软件配置

     1、Nginx配置文件

       user www www; #worker_processes 1; #因为我是4核cpu所以设置为4 worker_processes 4; error_log /web/logs/nginx_error.log crit; pid /usr/local/nginx/logs/nginx.pid; #Specifies the value for maximum file descriptors that can be opened by this process. worker_rlimit_nofile 51200; events { use epoll; worker_connections 51200; } http { include mime.types; default_type application/octet-stream; #charse gb2312; server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 64k; client_max_body_size 8m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; #增加超时，以避免502错误 fastcgi_connect_timeout 600; fastcgi_send_timeout 600; fastcgi_read_timeout 600; fastcgi_buffer_size 128k; fastcgi_buffers 8 128k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; 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-javascript text/css application/xml; gzip_vary on; #limit_zone crawler $binary_remote_addr 10m; server { listen 80; server_name test.abc.com; index phpinfo.php; root /web/www; #limit_conn crawler 20; #location /status { #stub_status on; #access_log off; #} location ~ .*/.(php|php5)?$ { fastcgi_pass unix:/tmp/php-cgi.sock; #fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fcgi.conf; } location ~ .*/.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*/.(js|css)?$ { expires 12h; } log_format access '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" $http_x_forwarded_for'; access_log /web/logs/access.log access; } server{ listen 80; server_name status.abc.com; location / { stub_status on; access_log off; } } server { listen 80; server_name admin.abc.com; index index.html index.htm index.php; root /web/www/phpmyadmin; location ~ .*/.(php|php5)?$ { fastcgi_pass unix:/tmp/php-cgi.sock; #fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fcgi.conf; } location ~ .*/.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*/.(js|css)?$ { expires 12h; } access_log off; } server { listen 80; server_name uc.abc.com; index index.html index.htm index.php; root /web/www/qm/uc; location ~ .*/.(php|php5)?$ { fastcgi_pass unix:/tmp/php-cgi.sock; #fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fcgi.conf; } location ~ .*/.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*/.(js|css)?$ { expires 12h; } access_log off; } server { listen 80; server_name www.abc.com; index index.php; root /web/www/qm/ss; location ~ .*/.(php|php5)?$ { fastcgi_pass unix:/tmp/php-cgi.sock; #fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fcgi.conf; } location ~ .*/.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*/.(js|css)?$ { expires 12h; } access_log off; } server { listen 80; server_name sns.abc.com; index index.php; root /web/www/qm/sns; location ~ .*/.(php|php5)?$ { fastcgi_pass unix:/tmp/php-cgi.sock; #fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fcgi.conf; } location ~ .*/.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*/.(js|css)?$ { expires 12h; } access_log off; } server { listen 80; server_name status.lnmp.org; location / { stub_status on; access_log off; } } }

     3、php配置文件

       在该配置文件中主要变化了一下部分

  [eaccelerator]
zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="128"
eaccelerator.cache_dir="/usr/local/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="300"
eaccelerator.shm_prune_period="120"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
eaccelerator.keys ="disk_only"
eaccelerator.sessions = "disk_only"
eaccelerator.content ="disk_only"

 

[Zend]
zend_optimizer.optimization_level=15;
zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/ZendOptimizer.so"

 

四、应用

     安装了康盛的UCenter、UCHome、SupeSite套装，组合安装成功后，对整个系统进行测试。

 

五、系统测试

        首先、使用了webbench对phpinfo.php进行了简单测试，测试结果如下：

     

测试工具	WebBench
并发用户数	运行时间(s)	每分钟加载页面数	每秒获得的字节数	成功的事务数	失败的事务数	请求页面	失败率	测试日期	测试主机

        其次、使用了LoadRunner对supesite的登录Action进行了测试，测试结果如下：
