作業程序：
1、當客戶請求的是靜態資源時，web服務器會直接把靜態資源回傳客戶端；
2、當客戶端請求的是動態資源時，httpd的php模塊會進行相應的動態資源運算，
如果此時程序還需要資料庫的資料作為運算引數時，php會連接mysql取得資料然后
進行運算，運算的結果轉為靜態資源由web服務器回傳到客戶端；

php各種版本官方支持時間：
https://www.php.net/supported-versions.php
php 的組態檔：/etc/php.ini, /etc/php.d/*.ini 組態檔在php解釋器啟動時被讀取
對組態檔的修改生效方法
Modules：重啟httpd服務
FastCGI：重啟php-fpm服務
注釋符：
以#開頭，純粹的注釋資訊
以 ; 開頭，用于注釋可啟用的directive
php.ini 配置參考檔案：
php.ini的核心配置選項檔案： http://php.net/manual/zh/ini.core.php
php.ini配置選項串列：http://php.net/manual/zh/ini.list.php
php常見設定：
max_execution_time= 30 最長執行時間30s
memory_limit=128M 生產不夠，可調大
display_errors=o? 除錯使用，不要打開，否則可能暴露重要資訊
display_startup_errors=o? 建議關閉
post_max_size=8M 最大上傳資料大小，生產可能調大，比下面項大
upload_max_?lesize =2M 最大上傳檔案，生產可能要調大
max_?le_uploads = 20 同時上傳最多檔案數 date.timezone =Asia/Shanghai 指定時區 short_open_tag=on 開啟短標簽
二進制部署mysql資料庫：
1、安裝基礎依賴包
yum install vim gcc gcc-c++ wget autoconf net-tools lrzsz iotop lsof iotop bash-completion curl policycoreutils openssh-server opensshclients postfix libaio -y
2、解壓MySQL原始碼包，并創建軟連接
[root@wufanecs src]# pwd
/usr/local/src
[root@wufanecs src]# tar xf 1mysql-5.6.46-linux-glibc2.12-x86_64.tar
[root@wufanecs src]# ls
mysql-5.6.46-linux-glibc2.12-x86_64.tar mysql-5.6.46-linux-glibc2.12-x86_64
[root@wufanecs src]# ln -sv /usr/local/src/mysql-5.6.46-linux-glibc2.12-x86_64 /usr/local/mysql
‘/usr/local/mysql’ -> ‘mysql-5.6.46-linux-glibc2.12-x86_64’
3、創建mysql用戶設定權限
[root@wufanecs src]# useradd mysql -s /sbin/nologin
[root@wufanecs src]# mkdir -pv /data/mysql /var/lib/mysql
mkdir: created directory ‘/data’
mkdir: created directory ‘/data/mysql’
mkdir: created directory ‘/var/lib/mysql’
[root@wufanecs src]# chown -R mysql.mysql /data /var/lib/mysql/
[root@wufanecs mysql]# ./scripts//mysql_install_db --user=mysql --datadir=/data/mysql --basedir=/usr/local/mysql/
4、準備啟動腳本
[root@wufanecs mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@wufanecs mysql]# chmod a+x /etc/init.d/mysqld
5、修改組態檔
[root@wufanecs mysql]# vim /etc/my.cnf
[mysqld]
datadir=/data/mysql
socket=/data/mysql/mysql.sock
user=mysql
symbolic-links=0
innodb_file_per_table=1
[client]
port=3306
socket=/var/lib/mysql/mysql.sock
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/tmp/mysql.sock
6、啟動mysql創建資料庫并授權
[root@wufanecs mysql]# /etc/init.d/mysqld start
Starting MySQL. [ OK ]
[root@wufanecs ~]# ln -sv /data/mysql/mysql.sock /var/lib/mysql/mysql.sock
‘/var/lib/mysql/mysql.sock’ -> ‘/data/mysql/mysql.sock’
[root@wufanecs ~]# /usr/local/mysql/bin/mysql
mysql> CREATE DATABASE wordpress;
Query OK, 1 row affected (0.00 sec)
mysql> GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpress'@'%' IDENTIFIED BY '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
mysql> show databases;

[root@wufanecs nginx-1.16.1]# make
[root@wufanecs nginx-1.16.1]# make install
4、創建nginx普通用戶
[root@wufanecs nginx-1.16.1]# useradd nginx -s /sbin/nologin -u 2000
[root@wufanecs nginx-1.16.1]# chown nginx.nginx -R /apps/nginx/
5、驗證版本及編譯引數
[root@wufanecs nginx-1.16.1]# /apps/nginx/sbin/nginx -V
nginx version: nginx/1.16.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)
built with OpenSSL 1.0.2k-fips 26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/apps/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module
6、準備php測驗頁：
[root@wufanecs nginx-1.16.1]# mkdir /data/nginx/wordpress -p
[root@wufanecs nginx-1.16.1]# vim /data/nginx/wordpress/index.php
[root@wufanecs nginx-1.16.1]# cat /data/nginx/wordpress/index.php
<?php
phpinfo();
?>
7、配置nginx：
[root@wufanecs nginx-1.16.1]# grep -v "#" /apps/nginx/conf/nginx.conf | grep -v "^$"
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root /data/nginx/wordpress;
index index.php index.html index.htm;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ \.php$ {
root /data/nginx/wordpress;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
}
[root@wufanecs nginx-1.16.1]# /apps/nginx/sbin/nginx -t
nginx: the configuration file /apps/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /apps/nginx/conf/nginx.conf test is successful
重啟nginx并訪問php狀態頁：
