从 0 开始在 VPS 上部署 Laravel (CentOS 7.2)

准备工作

之前写了一个 Ubuntu 系统的搭建教程，这次以 CentOS 7.2 为例，来说说怎么部署一个最简单的 Laravel 应用。我这里都是以 root 权限运行，如果不是 root 用户，请在命令前加上sudo。
先运行yum update -y

安装 lnmp 一键安装包

前期使用一键安装包可以有效防止莫名其妙出现的错误，简化安装步骤，这个安装过程预计需要1个小时左右的安装时间。
注意事项：
需要3GB以上硬盘剩余空间
需要128MB以上内存(如果为128MB的小内存VPS,Xen的需要有SWAP,OpenVZ的至少要有128MB以上的vSWAP或突发内存)，注意小内存请勿使用64位系统！
安装MySQL 5.6或5.7及MariaDB 10必须1G以上内存!

首先安装 screen：yum install -y screen
然后运行screen -S lnmp
如果网路出现中断，可以执行命令 screen -r lnmp 重新连接安装窗口
然后是安装 lnmp:wget -c http://soft.vpser.net/lnmp/lnmp1.3-full.tar.gz && tar zxf lnmp1.3-full.tar.gz && cd lnmp1.3-full && ./install.sh lnmp
安装过程中需要输入 MySQL 的 root 密码，后面设置可以自己设置，或者参考我下面的设置。

配置 nginx

参考如下修改 nginx 的配置

listen 80 default_server;
listen [::]:80 default_server;
root /var/www/laravel/public;
index index.php index.html index.htm;
# Make site accessible from http://localhost/
server_name localhost;
location / {
        try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$ {
        try_files $uri /index.php =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
}

部署 Laravel

安装 composer

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
mv composer.phar /usr/local/bin/composer

配置 Laravel

把文件larave上传至/home/wwwroot/目录下
修改storage文件夹权限chmod -R 775 /home/wwwroot/laravel/storage/
chown www:www -R /home/wwwroot/laravel/
编辑env将DB_PASSWORD=root中的root改为之前设置的密码
之后运行命令mv env .env
运行composer install，在国内的话，安装时间会比较长
