杂记：
1. linux crontab laravel
:
* * * * * /usr/bin/php /var/www/api.xxx.com/artisan schedule:run >> /dev/null 2>&1
2. rpm下载安装
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
3. mysql修改root初始密码，创建可远程登录新用户密码
ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘OMXlX222222222’;
grant all privileges on *.* to ‘dbusername’@’%’ identified by ‘0X=C!1i3333ddd’ with grant option;
flush privileges;
4. nginx与php-fpm两种通信方式: unix socket方式要比tcp的方式快，而且消耗资源少
listen = /run/php-fpm/www.sock
upstream php-fpm {
server unix:/run/php-fpm/www.sock;
}
unix:/run/php-fpm/www.sock;
fastcgi_pass unix:/run/php-fpm/www.sock;
fastcgi_pass 127.0.0.1:9000;
5. laravel storage 文件夹权限修改
chmod -R 777 /var/www/xxxx-prod/user/xxxx_user_api/storage
6. 将网站某个文件夹及子文件夹内容备份一份并重命名
cp -r /var/www/admin.xxxxx.com /var/www/admin.xxxxx.com_backup
