location /status { vhost_traffic_status_display; vhost_traffic_status_display_format html; } } }计算动态dns的流量如果域具有多个DNS A记录，则可以使用过滤器功能或proxy_pass中的变量计算域的各个IP的流量。http { vhost_traffic_status_zone; upstream backend { elb.example.org:80; } ... server { ... location /backend { vhost_traffic_status_filter_by_set_key $upstream_addr upstream::backend; proxy_pass backend; } } }计算域的各个IP的流量elb.example.org。如果elb.example.org有多个DNS A记录，将显示所有IP filterZones。在上述设置中，当NGINX启动或重新加载配置时，它会查询DNS服务器以解析域，并将DNS A记录缓存在内存中。因此，即使DNS管理员对DNS A记录进行了分区，DNS A记录也不会在内存中更改，除非NGINX重新启动或重新加载。http { vhost_traffic_status_zone; resolver 10.10.10.53 valid=10s ... server { ... location /backend { set $backend_server elb.example.org; proxy_pass http://$backend_server; } } }计算域的各个IP的流量elb.example.org。如果elb.example.org更改了DNS A记录，将同时显示旧IP和新IP ::nogroups。与第一个上游组设置不同，即使DNS管理员对DNS A记录进行了分析，第二个设置也能正常工作。永久保留统计数据http { vhost_traffic_status_zone; vhost_traffic_status_dump /var/log/nginx/vts.db; ... server { ... } }vhost_traffic_status_filter_by_host on; 会更加不同的server_name进行统计参考 : https://github.com/vozlt/nginx-module-vts

Nginx平滑处理echo模块收集POST日志 Nginx可以轻松处理大量的HTTP流量。每次NGINX处理连接时，将生成一个日志条目，以存储此连接（例如远程IP地址，响应大小和状态代码等）的某些信息。可在此处找到包含更多详细信息的完整记录信息集。在某些情况下，您可能更愿意存储请求的主体，特别是POST请求。幸运的是，NGINX生态系统是丰富的，并且包括很多 方便的模块。一个这样的模块是 回声模块，它提供的东西等是有用的功能：echo，time，和sleep 命令。在我们的用例中，要记录请求体，我们需要的是使用echo_read_request_body命令和$request_body变量（包含Echo模块的请求体）。然而，这个模块不是默认分配给NGINX，为了能够使用它，我们必须通过构建包含Echo模块的源代码的源代码构建NGINX。 以下步骤详细介绍了如何构建NGINX以便包含Echo模块（这里是完整的构建bash文件）使用以下命令下载NGINX和Echo的源代码：[root@linuxea ]# curl -Lk https://github.com/openresty/echo-nginx-module/archive/v0.58.tar.gz -o /usr/local/ [root@linuxea ]# tar xf v0.58.tar.gz -C /tmp/echo-nginx-module源nginx安装目录位于/usr/local/webserver/nginx，我们直接下载同样版本的nginx，进行编译./configure --user=www \ --group=www \ --prefix=/usr/local/webserver/nginx \ --with-http_stub_status_module \ --with-http_ssl_module \ --with-http_gunzip_module \ --with-http_mp4_module \ --with-http_flv_module \ --with-pcre \ --with-http_gzip_static_module \ --with-http_realip_module \ --with-ld-opt=-ljemalloc \ --add-module=/tmp/echo-nginx-module编译完成后，仅仅只进行make即可在/usr/local/webserver/nginx/sbin/下，删除或者重新命名nginxmv nginx old_nginxmv或者rm后nginx还是在运行着[root@linuxea sbin]# ps aux|grep nginx root 1796 0.0 0.9 124408 36180 ?

Nginx代理简单的优化 对sysctl.conf内核文件进行修改net.ipv4.tcp_fin_timeout = 2 表示如果套接字由本端要求关闭，这个参数决定了它保持在FIN-WAIT-2状态时间，默认为60秒，该参数对应系统路径：/proc/sys/net/ipv4/tcp_fin_timeout 60net.ipv4.tcp_tw_reuse = 1表示开启重用，允许TIME-WAIT sockets重新用于新的tcp连接，默认为0，表示关闭，系统路径：/proc/sys/net/ipv4/tcp_tw_reuse 0net.ipv4.tcp_tw_recycle = 1表示开启tcp连接中，TIME-WAIT sockets的快速回收，改参数对应系统路径为：/proc/sys/net/ipv4/tcp_tw_recycle = 1,默认0关闭net.ipv4.tcp_syncookies = 1表示开启SYN Cppkies功能，当出现SYN等待队列一处，启用cookies来处理，可防止少量的SYN攻击，centos5默认为1，表示开启，因此这个参数可以不添加，路径为：/proc/sys/net/ipv4/tcp_syncookies，默认为1net.ipv4.tcp_keepalive_time = 600表示当keepalive启用的时候，tcp发送keepalive消息的频度，缺省是2小时，改为10分钟，该参数对应系统路径为：/proc/sys/net/ipv4/tcp_keepalive_time,默认为7200秒net.ipv4.ip_local_port_range = 4000 65000用来设定允许系统打开的端口范围，既用于向外链接的端口范围，路径：/proc/sys/net/ipv4/ip_local_port_range = 32768 61000net.ipv4.tcp_max_syn_backlog = 8192表示SYN的队列长度，默认为1024，加大队列长度为8192，可以容纳更度等待连接的网络连接数，选项为服务器用于记录那些尚未收到客户端确认信息的连接请求数的最大值，改参数路径为：/proc/sys/net/ipv4/tcp_max_syn_backlognet.ipv4.tcp_max_tw_buckets = 36000表示系统同时保持TIME_WAIT套接字的最大数量，如果超过这个数，TIME_WAIT套接字将立即被清除并打印警告信息，默认为18000，对于apache，nginx,等服务器说可以调整稍低，如：改为5000-30000，不同业务服务器也可以改大，比如lvs,squid次参数对于squid效果不是很理想，可以控制TIME_WAIT套接字的最大数量，避免squid服务被大量TIME_WAIT套接字优化，该参数对应系统位置：/proc/sys/net/ipv4/tcp_max_tw_bucketsnet.ipv4.route.gc_timeout = 100net.ipv4.route.gc_timeout = 100 路由缓存刷新频率， 当一个路由失败后多长时间跳到另一个默认是300net.ipv4.tcp_syn_retries = 1在内核泛起建立连接之前发送SYN包的数量，路径为:/proc/sys/net/ipv4/tcp_syn_retries 5net.ipv4.tcp_synack_retries = 1决定内核放弃连接之前的发送的SYN+ACK包的数量，路径为：/proc/sys/net/ipv4/tcp_synack_retries默认为5net.core.somaxconn = 16384默认为128，这个参数用于调节系统同时发起的tcp连接数，在搞并发的请求中，默认的值可能会导致连接超时或者重传，因此，需要结合并发请求来进行调节，路径为:/proc/sys/net/core/somaxconn 128net.core.netdev_max_backlog = 16384当每个网络接口接收数据包的速率比内核处理这些包的速率快时，允许发送到队列的数据包的最大值，路径为：/proc/sys/net/core/netdev_max_backlog,默认为1000net.ipv4.tcp_max_orphans = 16384用于设定系统中最多有多少个TCP套接字不被关联到任何一个用户文件句柄，如果超过，孤立的连接将立即被复位并打印警告信息，这个限制知识为了防止简单的DOS攻击，不过效果并不是很理想化，更多的情况是增加这个数值，路径为：/proc/sys/net/ipv4/tcp_max_orphans 65536以下参数是对iptables防火墙的优化，防火墙不开会提示，可以忽略不理。net.ipv4.ip_conntrack_max = 25000000 net.ipv4.netfilter.ip_conntrack_max=25000000 net.ipv4.netfilter.ip_conntrack_tcp_timeout_established=180 net.ipv4.netfilter.ip_conntrack_tcp_timeout_time_wait=120 net.ipv4.netfilter.ip_conntrack_tcp_timeout_close_wait=60 net.ipv4.netfilter.ip_conntrack_tcp_timeout_fin_wait=120

linuxea: Nginx动静分离的几种方式 这篇文章简单的介绍nginx proxy_pass和一些配置。仅作为参考使用。proxy_pass属于ngx_http_proxy_module,此模块可以将请求发送到一台服务器上。proxy_pass放在location标签中，可使用http。如下：location /poy{ proxy_pass http://10.0.0.90; }参数：proxy_set_header，（当后端web服务器上有多个虚拟主机，需要使用header来区分代理的主机名）获取用户的主机名或者真是IP，以及代理者的IP地址server { listen 80; server_name www.linuea123.com; location / { root html; index index.html index.htm; proxy_pass http://backend; proxy_set_header Host $host; }获取用户的真是iP，截获客户请求地址(nginx开启即可，appche需要在LogFormat ""%{X-Forwareded-for}i添加)proxy_set_header Host $host;proxy_set_header X-Forwarded-For $remote_addr 获取用户的真是iP，截获客户请求地址client_body_buffer_size：用于指导客户端请求主题缓冲区大小，用户访问先保存到本地在传递给用户proxy_connect_timeout：表示与后端服务器连接的超时时间，既发起握手等待响应的超时时间proxy_send_timeoit:表示后端服务数据返回最短时间，超过则断开proxy_read_timeout:设置nginx从代理的后端服务器获取信息proxy_buffer_size：设置缓存区大小，默认缓冲大小指令：proxy_buffers设置location /poy{ proxy_pass http://10.0.0.90; proxy_set_header Host $host; }proxy.conf如下：proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 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;目录和扩展名分离测试（还有浏览器的分离）：upstream jingtai { server 10.0.1.10:80 weight=5 max_fails=10 fail_timeout=10s; server 10.0.1.11:80 weight=5 max_fails=10 fail_timeout=10s; } upstream dongtai { server 10.0.2.10:80 weight=5 max_fails=10 fail_timeout=10s; server 10.0.2.11:80 weight=5 max_fails=10 fail_timeout=10s; } server { listen 80; server_name www.linuxea.com; location / { root html; index index.html index.htm; proxy_pass http://dongtai; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } location /image/ { proxy_pass http://jingtai;扩展名分离location ~ .* (gif|jpg|jpeg|png|bmp|swf|css|js)$ { proxy_pass http://jingtai; include proxy.conf; } location ~ .*.

在看nginx_upstream那些基础 nginx负载均衡依赖upstream模块，支持的代理方式有proxy_pass，fastcgi_pass,memcached_pass1，upstream模块是放在nginx配置文件中的http{}标签中2，upstream默认算法是wrr，权重轮训3，upstream模块内部部分参数如下（参数和haproxy几乎一样）：server 10.0.0.54：80 这里的端口可换做域名，通过DNS做负载均衡weitht 权重，默认1，越大接收请求越多max_fails=2 fail_timeout=20s, 最大的尝试失败次数，默认为1,0表示禁止尝试，一般2-3次，可根据业务进行配置;fail_timeout=20s，失败超时时间，默认10s，通常2-3秒backup ，也可以成为热备。rs节点的高可用，当存活节点当即，则启动down ，维护模式，可配置ip_hash使用max_conns=NUMBER，限制连接数调度算法：rr轮询，weight权重，ip_hash黏贴-会话保持，fair第三方算法-根据节点的响应时间来分配请求（响应时间短的优先分配），url——hash根据地址hash-将每一个url定义到后端服务器-后端服务器为缓存服务器效果比较显著wget http://nginx.org/download/nginx-1.6.3.tar.gz tar xf nginx-1.6.3.tar.gz cd nginx-1.6.3 yum -y install pcre pcre-devel openssl-devel useradd nginx -s /usr/nologin -M ./configure \ --user=nginx \ --group=nginx \ --prefix=/usr/local/nginx \ --with-http_stub_status_module \ --with-http_ssl_module [root@nginx-proxy conf]# make && make install [root@nginx-proxy conf]# egrep -v "#|^$" nginx.conf.default > nginx.conf [root@nginx-proxy2 conf]# cat nginx.conf worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; upstream backend { server 10.0.0.54:80 weight=5; server 10.0.0.53:80 weight=5; # server 10.0.0.55:80 weight=5 backup; } server { listen 80; server_name www.linuea123.com; location / { root html; index index.html index.htm; proxy_pass http://backend; } } }
