LNMP代表Linux+Nginx+MySQL+PHP网站服务器架构。本文主要目的是为大家提供一种非常简单的方法，在阿里云上部署LNMP栈。
通过<阿里云ROS资源编排服务>，将VPC、NAT Gateway、ECS创建，LNMP栈部署过程自动化，使大家能够非常方便地部署一个LNMP栈。
急速部署LNMP栈
注意：
- 必须确保可以正确下载nginx-.rpm安装包，我们可以选择类似如下的URL：
- CentOS-7
- 我们选择的数据中心在上海/北京。
ROS模板安装LNMP栈
安装LNMP：关闭防火墙，关闭SELinux，安装nginx，MySQL和PHP。UserData如下：
"systemctl stop firewalld.service \n",
"systemctl disable firewalld.service \n",
"sed -i 's/^SELINUX=/# SELINUX=/' /etc/selinux/config \n",
"sed -i '/# SELINUX=/a SELINUX=disabled' /etc/selinux/config \n",
"setenforce 0 \n",
"yum install yum-priorities -y \n",
"yum -y install aria2 \n",
"aria2c $NginxUrl \n",
"rpm -ivh nginx-*.rpm \n",
"yum -y install nginx \n",
"systemctl start nginx.service \n",
"systemctl enable nginx.service \n",
"yum -y install php-fpm \n",
"systemctl start php-fpm.service \n",
"systemctl enable php-fpm.service \n",
"sed -i '/FastCGI/,/htaccess/s/ #/ /' /etc/nginx/conf.d/default.conf \n",
"sed -i '/FastCGI/s/^ / #/' /etc/nginx/conf.d/default.conf \n",
"sed -i '/htaccess/s/^ / #/' /etc/nginx/conf.d/default.conf \n",
"sed -i '/SCRIPT_FILENAME/s/\\/scripts/\\/usr\\/share\\/nginx\\/html\\//' /etc/nginx/conf.d/default.conf \n",
"yum -y install mariadb mariadb-server \n",
"systemctl start mariadb.service \n",
"systemctl enable mariadb.service \n",
"yum -y install php php-mysql php-gd libjpeg* php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-bcmath php-mhash \n",
"MDSRING=`find / -name mbstring.so` \n",
"echo extension=$MDSRING >> /etc/php.ini \n",
"systemctl restart mariadb.service \n",
"mysqladmin -u root password \"$dbrootpassword\" \n",
"$(mysql $dbname -u root --password=\"$dbrootpassword\" >/dev/null 2>&1 </dev/null); (( $? != 0 )) \n",
"echo CREATE DATABASE $dbname \\; > /tmp/setup.mysql \n",
"echo GRANT ALL ON $dbname.* TO \"$dbuser\"@\"localhost\" IDENTIFIED BY \"'$dbpassword'\" \\; >> /tmp/setup.mysql \n",
"mysql -u root --password=\"$dbrootpassword\" < /tmp/setup.mysql \n",
"$(mysql $dbname -u root --password=\"$dbrootpassword\" >/dev/null 2>&1 </dev/null); (( $? != 0 )) \n",
"cd /root \n",
"systemctl restart php-fpm.service \n",
"systemctl restart nginx.service \n",
"echo \\<?php > /usr/share/nginx/html/test.php \n",
"echo \\$conn=mysql_connect\\(\"'127.0.0.1'\", \"'$dbuser'\", \"'$dbpassword'\"\\)\\; >> /usr/share/nginx/html/test.php \n",
"echo if \\(\\$conn\\){ >> /usr/share/nginx/html/test.php \n",
"echo echo \\\"LNMP platform connect to mysql is successful\\!\\\"\\; >> /usr/share/nginx/html/test.php \n",
"echo }else{ >> /usr/share/nginx/html/test.php \n",
"echo echo \\\"LNMP platform connect to mysql is failed\\!\\\"\\; >> /usr/share/nginx/html/test.php \n",
"echo } >> /usr/share/nginx/html/test.php \n",
"echo phpinfo\\(\\)\\; >> /usr/share/nginx/html/test.php \n",
"echo \\?\\> >> /usr/share/nginx/html/test.php \n",
测试部署结果
创建完成后，查看资源栈概况：
浏览器中输入图中的的NginxWebsiteURL，得到如下结果，则部署成功：
