安装nginx
如用源码安装，需要先准备编译环境
yum -y install gcc gcc-c++ ncurses-devel unzip patch perl*
1）pcre安装
下载地址http://sourceforge.net/projects/pcre/files/pcre/8.37/pcre-8.37.tar.gz
[root@localhost local]# tar -zxvf pcre-8.37.tar.gz
[root@localhost local]# cd pcre-8.37
[root@localhost pcre-8.37]# ./configure
[root@localhost pcre-8.37]# make
[root@localhost pcre-8.37]# make install
2）安装zlib包
下载地址http://zlib.net/zlib-1.2.8.tar.gz
[root@localhost pcre-8.37]# cd /usr/local/
[root@localhost local]# tar -zxvf zlib-1.2.8.tar.gz
[root@localhost local]# cd zlib-1.2.8
[root@localhost zlib-1.2.8]# ./configure
[root@localhost zlib-1.2.8]# make
[root@localhost zlib-1.2.8]# make install
3）安装ssl
下载地址：http://www.openssl.org/source/
[root@localhost pcre-8.37]# cd /usr/local/
[root@localhost local]# tar -zxvf openssl-1.0.2c.tar.gz
4)安装nginx_upstream_check_module模块 （健康监测）
下载地址：https://github.com/yaoweibin/nginx_upstream_check_module/archive/master.zip
[root@localhost local]# unzip nginx_upstream_check_module-master.zip
##5）安装nginx
下载地址http://nginx.org/download/
[root@localhost zlib-1.2.8]# cd /usr/local/
[root@localhost local]# tar -zxvf nginx-1.9.2.tar.gz
[root@localhost local]# cd nginx-1.9.2
[root@unicorn01 nginx-1.9.2]# patch -p0 < /usr/local/nginx_upstream_check_module-master/check_1.9.2+.patch
[root@localhost nginx-1.9.2]# ./configure --prefix=/usr/local/nginx --add-module=/usr/local/nginx_upstream_check_module-master --with-pcre=/usr/local/pcre-8.37 --with-zlib=/usr/local/zlib-1.2.8 --with-http_ssl_module --with-openssl=/usr/local/openssl-1.0.2c
[root@localhost nginx-1.9.2]# make [root@localhost nginx-1.9.2]# make install
##6）配置nginx
```shell
root@localhost local]# cd /usr/local/nginx/conf/
[root@localhost conf]# vim nginx.conf
此处根据项目需求配置负载均衡和请求代理转发
例如:
upstream cluster {
# simple round-robin
server 192.168.0.1:80;
server 192.168.0.2:80;
check interval=5000 rise=1 fall=3 timeout=4000;
#check interval=3000 rise=2 fall=5 timeout=1000 type=ssl_hello;
#check interval=3000 rise=2 fall=5 timeout=1000 type=http;
#check_http_send "HEAD / HTTP/1.0\r\n\r\n";
#check_http_expect_alive http_2xx http_3xx;
} upstream group1 {
server 10.51.19.63:80;
}
server {
listen 80;
#listen 8602;
server_name localhost;
#proxy_redirect http://localhost:80/M00 /M00;
#charset koi8-r;
#access_log logs/host.access.log main;
#location / {
# root html;
# index index.html index.htm;
#} location / {
proxy_pass [http://cluster](http://cluster/);
}
location /nstatus {
check_status;
access_log off;
#allow SOME.IP.ADD.RESS;
#deny all;
}
location /group1/M00 {
proxy_pass http://group1;
#health_check match=not_redirect;
proxy_redirect off;
proxy_set_header Host $host;
#proxy_cache cache_one;
proxy_cache_valid 200 1h;
# proxy_cache_valid 301 1d;
# proxy_cache_valid any 1m;
expires 30d;
}

7）启动、重启、停止
[root@localhost conf]# /usr/local/nginx/sbin/nginx
重启：
[root@localhost conf]# /usr/local/nginx/sbin/nginx -s reload
停止：
[root@localhost conf]# /usr/local/nginx/sbin/nginx -s stop
验证配置文件：
[root@localhost conf]# /usr/local/nginx/sbin/nginx -t
8)nginx监控配置
location /status {
stub_status on; auth_basic "NginxStatus";
}
Active connections: 2
server accepts handled requests
3 3 54
Reading: 0 Writing: 1 Waiting: 1
解析：
Active connections //当前 Nginx 正处理的活动连接数。
server accepts handled requests //总共处理了3 个连接 , 成功创建 3 次握手,总共处理了54个请求。
Reading //nginx 读取到客户端的 Header 信息数。
Writing //nginx 返回给客户端的 Header 信息数。
Waiting //开启 keep-alive 的情况下，这个值等于 active - (reading + writing)，意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接
9）nginx出现异常开启日志分析
log_format main 'remote_user [
request" '
'body_bytes_sent "$http_referer" '
'"http_x_forwarded_for"'
'"upstream_status" "
request_time"';
access_log logs/access.log main;
参数说明示例
$remote_addr 客户端地址 211.28.65.253
$remote_user 客户端用户名称 --
$time_local 访问时间和时区 18/Jul/2012:17:00:01 +0800
$request 请求的URI和HTTP协议 "GET /article-10000.html HTTP/1.1"
$http_host 请求地址，即浏览器中你输入的地址（IP或域名） www.it300.com
192.168.100.100
$status HTTP请求状态 200
$upstream_status upstream状态 200
$body_bytes_sent 发送给客户端文件内容大小 1547
$http_referer url跳转来源 https://www.baidu.com/
ssl_protocol SSL协议版本 TLSv1
upstream_addr 后台upstream的地址，即真正提供服务的主机地址 10.10.10.100:80
upstream_response_time 请求过程中，upstream响应时间 0.002
切记：
1、首先，确保安装了OpenSSL库，并且安装Nginx时使用了–with-http_ssl_module参数。
2、证书拷至nginx目录，配置如下server
3、第一次配置https时必须重启nginx才能生效，不能reload！
