#重新配置后的问题：

configure:error: Cannot find MySQL header files under /application/mysql.

Note that theMySQL client library is not bundled anymore!

#不管怎么变更该数据库的路径，还是编译通还过

解决办法就是:

#mkdir /usr/lib/msyql –p   

#cp  /usr/lib64/mysql/*  /usr/lib/mysql/

然后进行./configure即可，如果服务器没有/usr/lib/mysql/ 目录，则在/usr/lib/目录下创建mysql目录即可

[root@Cactiphp-5.3.27]# cp php.ini-production  /application/php/lib/php.ini  #拷贝php的配置文件到PHP默认目录

在linux上编译安装PHP时，为什么php/etc/目录下没有找到php-fpm.conf.default这个文件?

解答：原因在拷贝配置文件执行时，有部分代码没有执行。

注意：当执行一大块代码结束后并没有报错，但没有执行的配置语句会重新显示出来。

[root@Cactiphp-5.3.27]# cd  /application/php/etc/     #配置文件php-fpm.confs

[root@Cactietc]# cp php-fpm.conf.default php-fpm.conf

启动PHP服务php-fpm:

[root@Cactietc]# /application/php/sbin/php-fpm

检查php服务php-fpm的进程及启动端口的情况：

[root@Cactietc]# ps -ef|grep php-fpm

配置Nginx支持PHP程序请求访问

#vi nginx.conf   #修改配置文件

location~.*\.(php|php5)?$ {

               root html;

              fastcgi_pass 127.0.0.1:9000;

              fastcgi_index index.php;

              include fastcgi.conf;

          }

#检查并启动Nginx

[root@Cacticonf]# ../sbin/nginx -t

nginx: theconfiguration file /application/nginx/conf/nginx.conf syntax is ok

nginx:configuration file /application/nginx/conf/nginx.conf test is successful

[root@Cacticonf]# ../sbin/nginx -s reload

测试LNMP环境生效的情况：

[root@Cactihtml]# echo "" >test_info.php

[root@Cactihtml]# cat test_info.php

PHP连接MySQL的情况进行测试：

[root@Cactihtml]# vi test_mysql.php

$link_id=mysql_connect('localhost','root','*****')or mysql_error();

if($link_id){

    echo "mysql successful byskyboy!";

}else{

    echo mysql_error();

  }

?>

下面部署一个wordpress程序服务：

1.先创建一个专用的数据库WordPress

[root@Cactihtml]# mysql -uroot –p

mysql>create database wordpress;

Query OK, 1row affected (0.00 sec)

mysql>show databases like 'wordpress';

+----------------------+

| Database(wordpress) |

+----------------------+

|wordpress            |

+----------------------+

1 row in set(0.00 sec)

Nginx及PHP环境配置准备：

         location / {

            root   html;

            index  index.php index.html index.htm;

        }

         location ~.*\.(php|php5)?$ {

              root  html;

              fastcgi_pass 127.0.0.1:9000;

              fastcgi_index index.php;

              include fastcgi.conf;

          }

[root@Cactihtml]# wget  https://tw.wordpress.org/wordpress-4.8-zh_TW.tar.gz

[root@Cactihtml]# tar xf wordpress-4.8-zh_TW.tar.gz

[root@Cactihtml]# mkdir blog

[root@Cactihtml]# mv wordpress blog/

[root@Cactihtml]# chown  -R nginx.nginx blog

测试情况：浏览器显示Filenot found.

解答：原因是解析不到程序，建设直接放到html目录下，避免发生找不到程序的问题。

 [root@Cactiwordpress]# cp wp-config-sample.php  wp-config.php

 [root@Cactiwordpress]# vi  wp-config.php #配置数据库名、用户名和密码即可

 配置成功。

以上是通过一台服务器架构LNMP;

下面通过两台服务器架设LNMP,也很简单：

.8服务器: 做Nginx服务器，将wordpress放到nginx的html目录下，配置wp-config.php文件。

/** WordPress数据库的名称 */

define('DB_NAME', 'wordpress');

/** MySQL数据库用户名 */

define('DB_USER', '***');

/** MySQL数据库密码 */

define('DB_PASSWORD', '*****');

/** MySQL主机 */

define('DB_HOST', '.9服务器IP');

.9服务器:做Mysql服务器，创建wordpress数据库。

技巧：当服务器每次重启的时候需要nginx、php-fpm服务自动启动。

#vi /etc/rc.local     #在默尾增加两条命令

/application/nginx/sbin/nginx   

/application/php/sbin/php-fpm

运行结果：http://117.40.239.8:8080/wordpress
