1、安装nginx
所需的prce库
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.10.tar.gz tar zxvf pcre-8.10.tar.gz cd pcre-8.10/ ./configure make && make install
安装nginx
wget http://nginx.org/download/nginx-0.8.54.tar.gz wget http://nginx.org/download/nginx-1.0.2.tar.gz tar zxvf nginx-1.0.2.tar.gz cd nginx-1.0.2/ ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module make && make install
创建Nginx日志目录
mkdir -p /home/nginx/logs chmod +w /home/nginx/logs chown -R www:www /home/nginx/logs
创建Nginx配置文件
在/usr/local/nginx/conf/目录中创建nginx.conf文件:
rm -f /usr/local/nginx/conf/nginx.conf vi /usr/local/nginx/conf/nginx.conf
输入以下内容:
user www www; worker_processes 8; error_log /home/nginx/logs/nginx_error.log crit; pid /usr/local/nginx/nginx.pid; worker_rlimit_nofile 65535; events { use epoll; worker_connections 65535; } http { include mime.types; default_type application/octet-stream; #charset gb2312; 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; 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$binary_remote_addr10m; server { listen 80; server_name www.test.com; index index.htm index.html index.jsp; root /home/htdocs/web/ROOT/; location ~ .*$ { index index.jsp; proxy_pass http://www.test.com:8080; } access_log logs/sp.imichat.com.log combined; error_page 404 = /404.html; } }
②、在/usr/local/nginx/conf/目录中创建fcgi.conf文件:
vi /usr/local/nginx/conf/fcgi.conf
输入以下内容:
fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; # PHP only, required if PHP was built with --enable-force-cgi-redirect fastcgi_param REDIRECT_STATUS 200;
启动Nginx
/usr/local/nginx/sbin/nginx
在不停止Nginx服务的情况下变更Nginx配置
修改/usr/local/nginx/conf/nginx.conf配置文件后,请执行以下命令检查配置文件是否正确:
/usr/local/nginx/sbin/nginx -t
如果屏幕显示以下两行信息,说明配置文件正确:
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully
重启nginx:
/usr/local/nginx/sbin/nginx -s reload
编写每天定时切割Nginx日志的脚本
创建脚本/usr/local/nginx/sbin/cut_nginx_log.sh
vi /usr/local/nginx/sbin/cut_nginx_log.sh
输入以下内容:
#!/bin/bash # This script run at 00:00 # The Nginx logs path logs_root_path="/home/nginx/logs/" logs_path=${logs_root_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/ mkdir -p ${logs_path} #日志文件名 ==================================================== logs_name="weblogs" logs_file=${logs_root_path}${logs_name}.log cut_logs_file=${logs_path}${logs_name}_$(date -d "yesterday" +"%Y%m%d").log mv ${logs_file} ${cut_logs_file} tar czf ${cut_logs_file}.tar.gz ${cut_logs_file} rm -f ${cut_logs_file}
#重新载入nginx配置文件
/usr/local/nginx/sbin/nginx -s reload
对这个脚本赋执行权限
# chmod +x /usr/local/nginx/sbin/cut_nginx_log.sh
设置crontab,每天凌晨00:00切割nginx访问日志
crontab -e
输入以下内容:
00 00 * * * /bin/bash /usr/local/nginx/sbin/cut_nginx_log.sh
2、配置nginx负载均衡
编辑nginx.conf
vim /usr/local/nginx/conf/nginx.conf
在server上面增加
upstream www.test.com { server www.test.com:8888; server www.test.com:8080; #ip_hash; }
www.test.com 是自己的服务器,最好是用域名
upstream后面的名字要与proxy_pass 这个名字一样,建议upstream后面的名字,proxy_pass 后面的名字,server_name 后面的名字一致
示例:
upstream www.test.com { server www.test.com:8888; server www.test.com:8080; }
#测试
server { listen 80; server_name www.test.com; index index.htm index.html index.jsp; root /home/htdocs/web/ROOT/; location ~ .*$ { index index.jsp; proxy_pass http://www.test.com; 注:做了负载均衡,这个后面就不能再加端口 } access_log logs/sp.imichat.com.log combined; error_page 404 = /404.html; }
注:如果负载均衡不成功,请检查是否没有经过nginx,80端口直接被转发到了tomcat服务的端口上
3、配置tomcat集群
优化tomcat 最大并发数,编辑server.xml
<Connector port="8080" maxHttpHeaderSize="8192" maxThreads="2048" minSpareThreads="100" maxSpareThreads="200" enableLookups="false" redirectPort="8443" acceptCount="500" connectionTimeout="20000" disableUploadTimeout="true" /> <Engine name="Catalina" defaultHost="localhost" jvmRoute="worker1"> <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" tcpListenAddress="127.0.0.1" />
修改web.xml
增加标签:<distributable/>
直接加在</web-app> 之前就可以了,这个是加入tomcat 的session 复制的,做tomcat 集群必须需要这一步,否则用户的session 就无法正常使用.
