在CentOS 6.4系统下编译安装LNMP（Linux, Nginx, MySQL, PHP）环境并配置PHP环境，可以按照以下步骤进行，这是一个较为详细的指导，请确保你有root权限或使用sudo命令来执行这些操作。
更新系统软件包
更新你的系统软件包：
sudo yum update y
安装Nginx
安装依赖项：
sudo yum install y gcc pcredevel zlibdevel openssldevel
下载和解压Nginx源码：
cd /usr/local/src wget http://nginx.org/download/nginx1.8.0.tar.gz tar zxvf nginx1.8.0.tar.gz cd nginx1.8.0
配置、编译和安装Nginx：
./configure prefix=/usr/local/nginx withhttp_ssl_module make && sudo make install
创建软链接到/usr/bin和启动脚本：
sudo ln s /usr/local/nginx/sbin/nginx /usr/bin/nginx sudo cp /usr/local/nginx/conf/nginx.conf /etc/nginx.conf sudo cp /usr/local/nginx/sbin/nginx /etc/init.d/nginx sudo chmod +x /etc/init.d/nginx chkconfig add nginx chkconfig nginx on
启动Nginx：
sudo service nginx start
安装MySQL
安装依赖项：
sudo yum install y perl cmake ncursesdevel bisondevel libaiodevel libmecabdevel libselinuxdevel pamdevel readlinedevel openssldevel
下载和解压MySQL源码：
cd /usr/local/src wget https://dev.mysql.com/get/Downloads/MySQL5.6/mysql5.6.27.tar.gz tar zxvf mysql5.6.27.tar.gz cd mysql5.6.27
配置、编译和安装MySQL：
cmake . DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
DMYSQL_DATADIR=/usr/local/mysql/data \
DSYSCONFDIR=/etc \
DMYSQL_TCP_PORT=3306 \
DEXTRA_CHARSETS=all \
DDEFAULT_CHARSET=utf8mb4 \
DDEFAULT_COLLATION=utf8mb4_general_ci \
DWITH_INNODB_STORAGE_ENGINE=1 \
DWITH_ARCHIVE_STORAGE_ENGINE=1 \
DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
DWITH_READLINE=system \
DENABLED_LOCAL_INFILE=1 \
DMYSQL_UNIX_ADDR=/var/run/mysqld/mysqld.sock
make && sudo make install初始化数据库并启动MySQL：
sudo /usr/local/mysql/scripts/mysql_install_db user=mysql basedir=/usr/local/mysql datadir=/usr/local/mysql/data sudo groupadd mysql sudo useradd r g mysql s /bin/false mysql sudo chown R mysql:mysql /usr/local/mysql /usr/local/mysql/data sudo /usr/local/mysql/bin/mysqld_safe user=mysql & sleep 5
设置MySQL为系统服务：
sudo cp /usr/local/mysql/supportfiles/mysql.server /etc/init.d/mysqld sudo chmod +x /etc/init.d/mysqld chkconfig add mysqld chkconfig mysqld on
设置root密码：
sudo /usr/local/mysql/bin/mysqladmin u root password 'yourpassword' sudo /usr/local/mysql/bin/mysql u root p'yourpassword' <<EOF FLUSH PRIVILEGES; GRANT ALL ON *.* TO 'root'@'localhost' IDENTIFIED BY 'yourpassword'; EOF
启动MySQL：
sudo service mysqld start
安装PHP
安装依赖项：
sudo yum install y gcc libxml2devel bzip2devel libjpegdevel libmcryptdevel libpngdevel freetypedevel libxsltdevel curldevel libcurldevel libcclientdevel glibcdevel glib2devel libidndevel openssldevel libeditlinedevel libtermcapdevel
下载和解压PHP源码：
cd /usr/local/src wget https://www.php.net/distributions/php5.6.27.tar.gz tar zxvf php5.6.27.tar.gz cd php5.6.27
配置、编译和安装PHP：
./configure prefix=/usr/local/php \
withconfigfilepath=/usr/local/php \
enableinlineoptimization \
withbz2 \
enablebz2 \
withcurl \
enablecurl \
withjpegdir \
withpngdir \
withfreetypedir \
withgd \
enablegdnativettf \
withopenssl \
withmcrypt=shared \
withzlib=shared \
enablembstring \
withxmlrpc \
enablexmlrpc \
withmysql=shared,/usr/local/mysql \
withpdomysql=shared,/usr/local/mysql \
withgettext \
withiconvdir \
withxsl \
enablesoap \
enableftp \
withapxs2=/usr/local/apache2/bin/apxs \
withfpmuser=www \
withfpmgroup=www \
enablefpm \
disabledebug \
disablerpath \
enableinlineoptimization
make && sudo make install创建软链接到PHP解释器：
sudo ln s /usr/local/php/bin/php /usr/bin/php
配置PHPFPM：
sudo cp sapi/phpfpm.service /etc/systemd/system/phpfpm.service sudo systemctl enable phpfpm.service sudo systemctl start phpfpm.service
配置Nginx与PHP的集成
编辑Nginx配置文件以支持PHP处理：
sudo vi /etc/nginx.conf
在http块中添加以下内容：
include /usr/local/nginx/conf/fastcgi.conf; include /usr/local/nginx/conf/fastcgi_params;
在server块中添加PHP处理配置：
server {
listen 80;
server_name localhost;
root html;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}重启Nginx服务：
sudo service nginx restart
至此，你已经成功在CentOS 6.4上编译并安装了LNMP（Linux, Nginx, PHP, MySQL）环境，你可以访问http://<your_server_ip> 查看Nginx欢迎页面，并测试PHP文件是否工作正常。
