安裝依賴包：

#yum install gcc bison bison-devel zlib-devel libmcrypt-devel mcrypt mhash-devel openssl-devel libxml2-devel libcurl-devel bzip2-devel readline-devel libedit-devel sqlite-devel libpng-devel libjpeg-devel freetype freetype-devel 

建立www使用者：

#groupadd www
#useradd -g www -s /sbin/nologin -M www
 

一、安裝Nginx1.12.1：

centos6.8的映象帶的Nginx版本是1.12.1

#yum install -y nginx 
#/etc/init.d/nginx start 

二、安裝mysql5.7.20:

#wget https://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm
#rpm -Uvh mysql57-community-release-el6-9.noarch.rpm 
#yum install mysql-community-server
#service mysqld start
#grep
 
 'temporary password' /var/log/mysqld.log  | awk '{print $NF}' 
#mysql -uroot -p
mysql>set global validate_password_policy=0;
mysql>set global validate_password_length=6; 
mysql>SET PASSWORD FOR 'root'@'localhost' =PASSWORD('******');

三、安裝PHP7.2.0
3.1原始碼編譯安裝

#wget rm -php-7.2.0.tar.xz
#tar xvJf
 
 php-7.2.0.tar -C /usr/local/
#cd /usr/local/php-7.2.0
#./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --with-mysqli --with-pdo-mysql --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-ftp  --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --disable-fileinfo --enable-maintainer-zts --with-libdir=lib64

# make 
# make install

上面configure步驟，可能會因為缺少依賴包而報錯，我這臺機器安裝過其他一些其他的包，不同的機器情況可能不一樣，在編譯的時候根據報錯資訊
用yum search 查詢依賴包並安裝，編譯完成之後是沒有error的！！！
make install 完成後也是沒有error的才可以進行後面的步驟。

3.2 配置PHP

#cp /usr/local/php-7.2.0/php.ini-development /usr/local/php/etc/php.ini

#cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

#cp /usr/local/php-7.2.0/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

#chmod +x /etc/init.d/php-fpm

#cp /usr/local/php/etc/php-fpm.d/www.conf.default/usr/local/php/etc/php-fpm.d/www.conf

3.3啟動php-fpm

# /etc/init.d/php-fpm start
Starting php-fpm  done 

3.4新增 PHP 命令到環境變數

vim ~/.bash_profile
cat ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:/usr/local/php/bin

export PATH

使之生效：

#. ~/.bash_profile

3.5檢視PHP版本：

# php -v
PHP 7.2.0 (cli) (built: Dec 17 2017 19:58:31) ( ZTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2017 Zend Technologies

3.6測試結果：

vim /usr/share/nginx/html/a.php
<?php
        phpinfo();
    ?>

vim /etc/nginx/conf.d/default.conf
cat /etc/nginx/conf.d/default.conf
server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index index.php index.html index.htm;
    }
    location ~ \.php$ {
        root           html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;
        include        fastcgi_params;
    }


    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

Nginx配置檔案修改的地方（在server裡面新增 index.php格式的檔案。增加一個location模組）
重新載入Nginx，重啟php-fpm

# /etc/init.d/nginx restart
Stopping nginx:                                            [  OK  ]
Starting nginx:                                            [  OK  ]
# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

測試：

# curl 192.168.1.185/a.php

或者直接到網頁上訪問。

至此，lnmp環境搭建成功
