工作过程：
1、当客户请求的是静态资源时，web服务器会直接把静态资源返回客户端；
2、当客户端请求的是动态资源时，httpd的php模块会进行相应的动态资源运算，
如果此时过程还需要数据库的数据作为运算参数时，php会连接mysql取得数据然后
进行运算，运算的结果转为静态资源由web服务器返回到客户端；
PHP官网：http://www.php.net
php各种版本官方支持时间：
https://www.php.net/supported-versions.php
php 的配置文件：/etc/php.ini, /etc/php.d/*.ini 配置文件在php解释器启动时被读取
对配置文件的修改生效方法
Modules：重启httpd服务
FastCGI：重启php-fpm服务
注释符：
以#开头，纯粹的注释信息
以 ; 开头，用于注释可启用的directive
php.ini 配置参考文档：
php.ini的核心配置选项文档： http://php.net/manual/zh/ini.core.php
php.ini配置选项列表：http://php.net/manual/zh/ini.list.php
php常见设置：
max_execution_time= 30 最长执行时间30s
memory_limit=128M 生产不够，可调大
display_errors=off 调试使用，不要打开，否则可能暴露重要信息
display_startup_errors=off 建议关闭
post_max_size=8M 最大上传数据大小，生产可能调大，比下面项大
upload_max_filesize =2M 最大上传文件，生产可能要调大
max_file_uploads = 20 同时上传最多文件数 date.timezone =Asia/Shanghai 指定时区 short_open_tag=on 开启短标签
1、安装基础依赖包
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、解压MySQL源码包，并创建软连接
[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、创建mysql用户设置权限
[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、准备启动脚本
[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、修改配置文件
[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、启动mysql创建数据库并授权
[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 src]# wget https://nginx.org/download/nginx-1.16.1.tar.gz
[root@wufanecs src]# tar xf nginx-1.16.1.tar.gz
[root@wufanecs src]# cd nginx-1.16.1/
3、编译nginx
[root@wufanecs nginx-1.16.1]# ./configure --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
[root@wufanecs nginx-1.16.1]# make
[root@wufanecs nginx-1.16.1]# make install
4、创建nginx普通用户
[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、验证版本及编译参数
[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

[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
重启nginx并访问php状态页：
[root@wufanecs nginx-1.16.1]# /apps/nginx/sbin/nginx -s reload
隐藏nginx版本信息
vim /apps/nginx/conf/nginx.conf
server_tokens off; #http 配置项
隐藏PHP版本：
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_hide_header X-Powered-By;
#fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
