一、起因
最近想尝试体验下laravel框架，由于框架对php版本大于5.6.4，自己服务器的php版本才5.4,因此一次性升级到php7。参考官网的laravel服务器要求：https://laravel.com/docs/5.3/installation
PHP >= 5.6.4
OpenSSL PHP Extension
PDO PHP Extension
Mbstring PHP Extension
Tokenizer PHP Extension
XML PHP Extension
二、Ubuntu通过apt-get升级PHP7
添加ppa(https://www.linuxdashen.com/debian%E5%92%8Cubuntu%E6%9C%8D%E5%8A%A1%E5%99%A8%E5%8D%87%E7%BA%A7php7)sudo apt-get install python-software-properties software-properties-common sudo add-apt-repository ppa:ondrej/php sudo apt-get update
安装PHP7
sudo apt-get install php7.0-fpm php7.0-mysql php7.0-common php7.0-curl php7.0-mbstring
三、验证php7.0是否安装成功
php -v
发现还是老的版本，同时发现有一个ph7.0命令：
root:~# php7.0 -v PHP 7.0.13-1+deb.sury.org~precise+1 (cli) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies with Zend OPcache v7.0.13-1+deb.sury.org~precise+1, Copyright (c) 1999-2016, by Zend Technologies
通过浏览器访问phpinfo()发现还是老的版本，默认使用的还是老版本，存在两个版本共存，下面通过php-fpm修改。
四、升级php-fpm
升级php7.0的同时会自动升级php-fpm到7.0，执行ps -ef | grep php-fpm发现有一个原有的
php-fpm和一个
/etc/php/7.0/fpm/php-fpm.conf,把老的kill掉，再通过浏览器执行，发现报502错误。*
解决方式：在php-fpm配置文件（
/etc/php/7.0/fpm/php-fpm.conf）加上下面几行即可。
[www] user=www group=www listen = 127.0.0.1:9000
重启
php-fpm
service php-fpm restart
验证访问成功，并执行phpinfo()确认是php7.0最新版
原因：php-fpm是绑定本地9000端口，nginx通过
fastcgi_pass 127.0.0.1:9000;将请求转发到本地9000端口上。
五、配置laravel目录到nginx上
下载laravel一键安装包（http://www.golaravel.com/download/）：
解压到nginx的root目录
配置nginx，注意
root一定要指向到public目录:
# 完整版
server {
listen 80 default_server;
# 设定网站根目录
root /alidata/www/default/laravel-master/public;
# 网站默认首页
index index.php index.html index.htm;
# 服务器名称，server_domain_or_IP 请替换为自己设置的名称或者 IP 地址
server_name test.com
# 修改为 Laravel 转发规则
location / {
try_files $uri $uri/ /index.php?$query_string;
}
# PHP 支持
location ~ \.php$ {
try_files $uri /index.php =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}浏览器访问
test.com验证：
六、使用lavarel报PDOException异常
使用lavarel操作mysql抛异常，数据库的配置是正确的，完整异常信息如下：Whoops, looks like something went wrong.

at Kernel->handle(object(Request)) in index.php line 55
google后发现是配置问题：http://stackoverflow.com/questions/35240414/laravel-5-pdoexception-could-not-find-driver
解决步骤：
- 找到php.ini（通过phpinfo()查看）
- 找到这行
extension=php_pdo_mysql.dll，取消注释
- 增加一行
extension=pdo_mysql.so
- 执行安装
sudo apt-get install php-mysql
解决。
七、service php-fpm restart
提示Unknown job
使用service php-fpm restart提示以下错误：
root:/alidata/server/nginx/conf/vhosts# service php-fpm start Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service php-fpm start initctl: Unknown job: php-fpm Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start(8) utility, e.g. start php-fpm
原因php-fpm是一个upstart任务，应该改用
restart php-fpm
搞定。
八、感受
碰碰撞撞升级好了PHP7和安装好laravel，过程比较曲折和受挫，还好最后都解决了，我给的建议是遇到问题要学会google，并发挥自己的理解能力，很多时候其实错误提示已经很明显告知具体是什么错误，要学会看英语文档。结果很重要，中间的解决过程、解决思路更重要。享受过程，对技术保持热情。
