一、nginx 做静态服务器

上传相关文件，生成如下路径
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

浏览器访问：
这个时候我们可以把static静态页面给拆分出来
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;
}
}
}

将静态文件迁移到/data/db目录下，并重启nginx服务。
mv html/static/ /data/db/
/data/app/nginx/sbin/nginx -t
/data/app/nginx/sbin/nginx -s reload

测试图片是否能否获取：
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

1.1 对图片开启gzip压缩
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

对比两次响应头信息，开启gzip 压缩后响应头多了Content-Encoding: gzip，开启压缩成功。
二、nginx 反向代理后端服务器
2.1 配置nginx环境
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 安装PHP 环境
下载PHP文件，并安装基础依赖包
wget http://cn2.php.net/distributions/php-7.1.2.tar.gz
yum -y install libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel libcurl-devel libjpeg-turbo-devel openssl openssl-devel

编译安装
./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/

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

好了，PHP 7 已经安装好，下面验证一下
shell > /data/app/php7/bin/php -v
PHP 7.0.5 (cli) (built: Apr 8 2016 00:08:04) ( NTS )

再查看下已经安装的模块
/data/app/php7/bin/php -m

接着配置 php-fpm文件
# copy php-fpm 的配置文档
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

其中 www.conf 中要留意以下这个值
listen = 127.0.0.1:9000
配置 php-fpm 启动服务脚本
修改启动脚本，把里边 prefix 相关的内容用实际路径代替
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
# 重新载入 systemd
systemctl daemon-reload
systemctl start php-fpm
ss -lntup |grep 9000
