一、nginx 做靜態服務器
HTML頁面如下
<!DOCTYPE html> <html lang="en"> <head><meta charset="UTF-8"><title>Title</title> </head> <body><h1>圖片展示</h1>
<div>
<img src="/static/images/1.png">
</div>
</body>
</html>

上傳相關文件,生成如下路徑
tree html/ html/ ├── index.html └── static└── images└── 1.png ## 配置nginx.conf 配置文件 worker_processes 1; events {worker_connections 1024; } http {include mime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65;server {listen 80;server_name localhost;location / {root html;index index.html index.htm;}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}} } /data/app/nginx/sbin/nginx -t nginx: the configuration file /data/app/nginx-1.10.3/conf/nginx.conf syntax is ok nginx: configuration file /data/app/nginx-1.10.3/conf/nginx.conf test is successful /data/app/nginx/sbin/nginx -s reload- 1

瀏覽器訪問:
這個時候我們可以把static靜態頁面給拆分出來
worker_processes 1; events {worker_connections 1024; } http {include mime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65;server {listen 80;server_name localhost;location / {root html;index index.html index.htm;}location /static/ {root /data/db;}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}} }- 1

將靜態文件遷移到/data/db目錄下,并重啟nginx服務。
mv html/static/ /data/db/ /data/app/nginx/sbin/nginx -t /data/app/nginx/sbin/nginx -s reload- 1

測試圖片是否能否獲取:
curl -I http://192.168.56.12/static/images/1.png HTTP/1.1 200 OK Server: nginx/1.10.3 Date: Sun, 08 Apr 2018 09:31:35 GMT Content-Type: image/png Content-Length: 32239 Last-Modified: Sun, 08 Apr 2018 09:21:26 GMT Connection: keep-alive ETag: "5ac9df16-7def" Accept-Ranges: bytes- 1

1.1 對圖片開啟gzip壓縮
worker_processes 1; events {worker_connections 1024; } http {include mime.types;default_type application/octet-stream;sendfile on; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.1; gzip_comp_level 6; gzip_types image/png; gzip_vary on;keepalive_timeout 65; server {listen 80;server_name localhost;location / {root html;index index.html index.htm;}location /static/ {root /data/db;}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;} }}
/data/app/nginx/sbin/nginx -t
/data/app/nginx/sbin/nginx -s reload

對比兩次響應頭信息,開啟gzip 壓縮后響應頭多了Content-Encoding: gzip,開啟壓縮成功。
二、nginx 反向代理后端服務器
2.1 配置nginx環境
user www www; worker_processes 8; error_log /data/logs/nginx_error.log crit; pid /usr/local/webserver/nginx/nginx.pid; #Specifies the value for maximum file descriptors that can be opened by this process. 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;
include gzip.conf;
include blog.biglittle.cn.conf;

2.2 安裝PHP 環境
下載PHP文件,并安裝基礎依賴包
wget http://cn2.php.net/distributions/php-7.1.2.tar.gzyum -y install libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel libcurl-devel libjpeg-turbo-devel openssl openssl-devel- 1

編譯安裝
./configure --prefix=/data/app/php-7.1.2 --enable-fpm --with-fpm-user=nginx --with-fpm-group=nginx --with-mysqli --with-zlib --with-curl --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-openssl --enable-mbstring --enable-xml --enable-session --enable-ftp --enable-pdo -enable-tokenizer --enable-zip --enable-bcmath --enable-sockets --with-gettext make && make install ln -s /data/app/php-7.1.2/ /data/app/php7 cp php.ini-development /data/app/php7/lib/php.ini cp sapi/fpm/php-fpm.service /usr/lib/systemd/system/- 1

修改配置文件
vim /data/app/php7/lib/php.ini # 查找 mysqli.default_socket,修改成: mysqli.default_socket = /data/app/mysql/mysql.sock date.timezone = PRC- 1

好了,PHP 7 已經安裝好,下面驗證一下
shell > /data/app/php7/bin/php -v PHP 7.0.5 (cli) (built: Apr 8 2016 00:08:04) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies- 1

再查看下已經安裝的模塊
/data/app/php7/bin/php -m- 1
接著配置 php-fpm文件
# copy php-fpm 的配置文檔 cp /data/app/php7/etc/php-fpm.conf.default /data/app/php7/etc/php-fpm.conf cp /data/app/php7/etc/php-fpm.d/www.conf.default /data/app/php7/etc/php-fpm.d/www.conf- 1

其中 www.conf 中要留意以下這個值 listen = 127.0.0.1:9000
配置 php-fpm 啟動服務腳本
修改啟動腳本,把里邊 prefix 相關的內容用實際路徑代替
vim /usr/lib/systemd/system/php-fpm.service PIDFile=/usr/local/php7/var/run/php-fpm.pid ExecStart=/usr/local/php7/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php7/etc/php-fpm.conf # 重新載入 systemd systemctl daemon-reload systemctl start php-fpm ss -lntup |grep 9000- 1

2.3 編寫PHP測試文件
vim /data/app/nginx/html/hello.php 編寫一個PHP測試文件。
<html><head><title>PHP 測試</title></head><body><?php phpinfo(); ?></body> </html>- 1
