1、安装依赖关系
#有yum源时安装依赖 yum install gcc gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel -y
无yum源时自行上传依赖软件包，进入该文件夹
cd /yilai yum localinstall *
2、解压nginx
tar zxvf nginx-linux-1.18.0.tar.gz
3、设置
cd nginx-1.18.0 ./configure --prefix=/www/server/nginx --with-http_ssl_module --with-stream --with-stream_ssl_module
4、编译安装:
make make install
5、控制nginx
启动 /www/server/nginx/sbin/nginx 停止 /www/server/nginx/sbin/nginx -s stop 载入配置 /www/server/nginx/sbin/nginx -s reload
6、修改配置
vim /www/server/nginx/conf/nginx.conf
修改user ngbody为：
user nginx;
修改线程worker_processes 1为：
worker_processes auto;
修改最大连接数worker_connections 1024为：
worker_connections 65530;
在最后一行的}上面插入一行：
include /www/server/nginx/conf/conf.d/*.conf;
注：轮询负载均衡需在http {下新加如下内容，进行跳转时转到cibheat上。
upstream heat{
server 192.168.0.100:8080;
server 192.168.0.101:8080;
server example.com:8080;
}
server段：
server {
listen 80;
server_name www.abc.com;
location / {
proxy_pass "http://heat";
proxy_set_header X-Forwarded-For $remote_addr;
}
}
7、新建配置文件目录
mkdir /www/server/nginx/conf/conf.d
8、新建配置文件
vim /www/server/nginx/conf/conf.d/heat.conf
php项目写入如下内容：
server {
listen 8080;
server_name www.qqq.com 192.168.1.205;
root /www/server/www/heat/public;
location /admin {
index index.html index.htm index.php;
if (!-e $request_filename){
rewrite ^(.*)$ /index.php?s=$1 last; break;
}
}
location ~ \.php(.*)$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
include fastcgi_params;
}
access_log /www/server/nginx/logs/heat.log;
error_log /www/server/nginx/logs/heat.error.log;
}
9、反向代理
server {
listen 80;
server_name www.qqq.com;
location /
{
proxy_pass "http://127.0.0.1:8080";
proxy_set_header X-Forwarded-For $remote_addr;
#下面这行的作用是把原http请求的Header中的Host字段也放到转发的请求里。如果不加这一行的话，nginx转发的请求header里就不会有Host字段，而服务器是靠这个Host值来区分你请求的是哪个域名的资源的。
proxy_set_header Host $host:$server_port;
#获取真实IP
proxy_set_header X-Real-IP $remote_addr;
}
}
10、设置
关闭版本显示
server_tokens off;
上传文件大小限制
client_max_body_size 1024M;
设置为on表示启动高效传输文件的模式
sendfile on;
保持连接的时间，默认65s
keepalive_timeout 1800s;
11、载入配置
/www/server/nginx/sbin/nginx -s reload
12、加入启动项
sed -i '$a/bin/su - nginx -c "/www/server/nginx/sbin/nginx"' /etc/rc.d/rc.local && chmod +x /etc/rc.d/rc.local
