记一次阿里云 ECS 服务器数据盘无损扩容
原数据盘 20G 扩容至 25G,购买后通过 SSH 登陆实例进行操作;
操作步骤完全参考阿里云帮助即可:https://help.aliyun.com/document_detail/25452.html

值得注意的点是 fdisk 命令操作时, 是使用 fdisk /dev/vdb
而不是 fdisk /dev/vdb1
,这里没仔细看坑了我好长时间,一直扩容失败;
扩容成功。
解决 Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ 错误
安装完 MySQL ,进行运行测试,报 Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ 错误,
[root@localhost mysql]# /usr/local/mysql/bin/mysqld_safe 131206 22:42:51 mysqld_safe Logging to ‘/var/log/mysqld.log’. 131206 22:42:51 mysqld_safe Starting mysqld daemon with databases from /data/mysql/data 131206 22:42:57 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended [root@localhost mysql]# /usr/local/mysql/bin/mysql ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)
检查一下 MySQL 的运行状态
[root@localhost mysql]# ps -ef | grep mysql root 32092 2108 0 22:43 pts/0 00:00:00 grep mysql
查看 /tmp 文件夹的确没有 mysql.sock 文件,
通过 find 命令查找
[root@localhost /]# find / -name mysql.sock /var/lib/mysql/mysql.sock
原来安装到 /var/lib/mysql/mysql.sock 这个位置啦,我们需要修改 my.cnf 文件
[root@localhost /]# vi /usr/local/mysql/my.cnf [client] character-set-server = utf8 port = 3306 socket = /var/lib/mysql/mysql.sock ……
保存之后即出,重新启动 MySQL 。

解决: Homestead 环境下, yarn install –no-bin-links, NPM run dev, 命令报错
执行以下命令:
- 1
$ rm -rf node_modules
- 2
$ yarn config set registry http://registry.cnpmjs.org
- 3
$ yarn install --no-bin-links
- 4 接下来打开 pakage.json 修改, 去掉 package.json 中的四处 cross-env
"scripts": { "dev": "npm run development", "development": "NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "watch": "NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "watch-poll": "npm run watch -- --watch-poll", "hot": "NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js", "prod": "npm run production", "production": "NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js" },
- 5.执行
$ npm run watch-poll
或者npm run dev
- 6.完成

国家标准《国民经济行业分类》(GBT4754-2011) 数据库 MySQL 版本下载
国家标准《国民经济行业分类》(GBT4754-2011) 数据库 SQL 版本,纠正了一些错误数据,含 PID,作为快速索引。

解决 WordPress 后台主题中只显示一个主题不显示其他主题的问题
网站 ald 安装的一些记录
Call to undefined function Think\Session\Driver\mysql_connect()
Conf/common.php 的 SESSION_TYPE 留空,如写 db 则以 mysql 为驱动,会报上述错误
nginx 引入文件 include vhost/other/osv2_nginx.conf;

nginx 主要配置项 重写 thinkphp index.php 文件,取消引入 php7 的 pathinfo.php,引入 osv2_nginx.conf 重写文件
删除 .user.ini 文件,可能造成 No input file specified
