数据库备份与恢复

一、备份脚本

#!/usr/bin/bash
path_current=$(cd "$(dirname "$0")"; pwd)
name_current=$(basename "$0" .sh)
echo $path_current
echo $name_current
 
if [ ! -d $path_current/backup/ ];then
   echo "create backup path: $path_current/backup"
   mkdir -p $path_current/backup
fi
 
path_backup=$path_current/backup/
echo "backup path: ${path_backup}"
 
dball=(commams-bigdata commams-bos commams-coupon commams-device commams-face commams-goods commams-log commams-logistics commams-marketing commams-member commams-oa commams-oauth commams-order commams-partner commams-pay commams-payaccount commams-peripherals commams-sms commams-wallet commams-wms)
for db in ${dball[@]};do
   if [ ! -f ${path_backup}/"$db".sql ];then
      echo "backup next database:$db"
      mysqldump --host xxxxx --port 196227  -u abc -p'yyy3' --set-gtid-purged=off --databases "$db" > ${path_backup}/"$db".sql
      if [ $? -ne 0 ]; then
         rm -f ${path_backup}/"$db".sql
         echo "failed to backup the database."
         exit 1
      fi
   fi
done
echo "success to backup database from production"

二、restore.sh恢复脚本

#!/usr/bin/bash
path_current=$(cd "$(dirname "$0")"; pwd)
name_current=$(basename "$0" .sh)
echo $path_current
echo $name_current
 
if [ ! -d $path_current/backup/ ];then
   echo "should first backup database."
   exit 1
fi
 
path_backup=$path_current/backup/
echo "backup path: ${path_backup}"
 
dball=(commams-bigdata commams-bos commams-coupon commams-device commams-face commams-goods commams-log commams-logistics commams-marketing commams-member commams-oa commams-oauth commams-order commams-partner commams-pay commams-payaccount commams-peripherals commams-sms commams-wallet commams-wms)
 
for db in ${dball[@]};do 
   if [ -f ${path_backup}/"$db".sql ];then
      echo "restore database:$db"
      mysql --host sxxxxx --port 3307  -uroot -p'123456' < ${path_backup}/"$db".sql && echo "$db is ok"
   fi
done
echo "success to restore database from production"

xdebug3的调试开启方式

xdebug2和xdebug3的开启调试方式是不同的。

此外xdebug3的默认端口改为9003了，故需要修改PHPSTORM的调试端口。
——xdebug3—–的开启方式。
zend_extension=”xdebug-3.0.1.so”
xdebug.mode=debug

GIT误删库如何恢复

转:
误操作删除服务器上git仓库的处理方法

说明：

git 服务器上仓库代码不小心被删除了，但是通过git clone下来的code存在

另外git 服务器上没有建立任何branch信息；

1.在之前clone过服务器代码的客户端机器上，找到clone下来的代码目录，

执行git remote -vv
查询原来git 仓库所在服务器的IP地址以及路径；

2.根据步骤1上查询的结果，在服务器上找到对应路径，创建git仓库；

git init –bare

3.在客户端之前clone 代码所在目录，强制push客户端的代码至服务器

git push origin master –force

这样原来clone下来的代码以及change log等信息，就会被强制clone到服务器上；

说明：此处必须加–force选项，否则会因服务器上仓库信息与客户端仓库信息不匹配导致push失败
