1. 安装相关依赖
yum install readline-devel pcre-devel openssl-devel zlib-devel gcc gcc-c++ gd-devel libxml2-devel
2. 添加nginx第三方模块
1) pcre（rewrite正则表达式的支持）：ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
2) libressl（加密解密）：http://ftp.openbsd.org/pub/OpenBSD/LibreSSL/
3) openssl（加密解密）：ftp://ftp.openssl.org/source
4) zlib（数据压缩）：http://zlib.net/ http://zlib.net/zlib-1.2.8.tar.gz
5) ngx_cache_purge（缓存清除扩展模块）：https://github.com/FRiCKLE/ngx_cache_purge/archive/2.3.tar.gz
6) nginx_upstream_check_module（负载均衡）：https://github.com/yaoweibin/nginx_upstream_check_module/archive/v0.3.0.tar.gz
7) echo-nginx-module（模块，方便输出用的）：https://github.com/openresty/echo-nginx-module/archive/v0.60.tar.gz
8）nginx：http://nginx.org/download/nginx-1.10.1.tar.gz
3. nginx编译安装
nginx 1.10.2 install on CentOS 6.x:
./configure --prefix=/usr/local/nginx \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_addition_module \
--with-http_sub_module \
--with-http_dav_module \
--with-http_flv_module \
--with-http_mp4_module \
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_random_index_module \
--with-http_secure_link_module \
--with-http_stub_status_module \
--with-http_auth_request_module \
--with-threads \
--with-stream \
--with-stream_ssl_module \
--with-http_slice_module \
--with-mail \
--with-mail_ssl_module \
--with-file-aio \
--with-http_v2_module \
--with-ipv6 \
--with-pcre=../pcre-8.40 \
--with-pcre-jit \
--with-openssl=../libressl-2.5.1 \
--with-zlib=../zlib-1.2.11/ \
--add-module=../ngx_cache_purge-2.3/ \
--add-module=../nginx_upstream_check_module-0.3.0/ \
--add-module=../echo-nginx-module-0.60/ \
--with-ld-opt=-lrt
make
make install
4.yum 安装nginx
yum install nginx
5.修改防火墙
/etc/sysconfig/iptables
/etc/init.d/iptables stop
/etc/init.d/iptables start
#80端口可以访问
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
6.nginx 配置文件结构
默认的配置文件：
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
server {
listen 80;
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;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
7.nginx 文件结构
events { #events块
...
}
http #http块

... #http全局块
server #server块
{
... #server全局块
location #location块
{
...
}
location
{

server

... #http全局块
}
user www www; #用户组
worker_processes 2; #nginx要开启的进程数
worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000; #使用该选项可以绑定worker进程和CPU
pid /var/run/nginx.pid; #nginx进程运行文件存放地址
events {
accept_mutex on; #设置网路连接序列化，防止惊群现象发生，默认为on
multi_accept on; #设置一个进程是否同时接受多个网络连接，默认为off

worker_connections 1024; #最大连接数，默认为512
}
http {
include mime.types; #文件扩展名与文件类型映射表
default_type application/octet-stream; #默认文件类型，默认为text/plain
#access_log off; #取消服务日志
log_format myFormat '$remote_addr–$remote_user [$time_local] $request $status $body_bytes_sent $http_referer $http_user_agent $http_x_forwarded_for'; #自定义格式
access_log log/access.log myFormat; #combined为日志格式的默认值
sendfile on; #允许sendfile方式传输文件，默认为off，可以在http块，server块，location块。
sendfile_max_chunk 100k; #每个进程每次调用传输数量不能大于设定的值，默认为0，即不设上限。
keepalive_timeout 65; #连接超时时间，默认为75s，可以在http，server，location块。
error_page 404 https://www.baidu.com; #错误页
#负载均衡
upstream mysvr {
server 127.0.0.1:7878;
server 192.168.10.121:3333 backup;
}
server {
listen 80; #监听端口
root path; #根目录
index index.html; #设置默认页
server_name a.com; #监听地址
location / { #请求的url过滤，正则匹配，~为区分大小写，~*为不区分大小写。
