skipping. By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? Query OK, 0 rows affected (0.00 sec) MariaDB [mysql] 接着就可以远程登陆数据库了 之后要修改手撕包菜程序里面的连接密码 首先关闭相关的进程 ps -ef |grep python 一般就是下面几个进程 root 958 1 0 20:51 ?
添加allow-query属性： allow-query { localhost; 要添加的zone配置在/etc/named/named.conf.local,如下： zone "example.com" { type master; Negative Cache TTL IN NS dns1.example.com. dns1 IN AAAA 2001:250:4000:2000::44 host1.example.com. IN AAAA 2001:250:4000:2000::41 host2.example.com. IN AAAA 2001:250:4000:2000::43 创建逆向解析文件reserve mapping $TTL 604800 @ IN SOA example.com. admin.example.com ( 3 ; name servers IN NS dns1.example.com. ;
Linux shell流程控制 单分支的if语句 例子 1、使用单分支的if条件语句来判断/home/huanyu/shell/zz文件是否存在，若存在就结束条件判断和整个Shell脚本，反之则去创建这个目录 #!/bin/bash # 通过for循环批量创建用户 read -p "Enter the Users Password:" PASSWD for UNAME in `cat users.txt` do id $UNAME /home/huanyu/shell/null // 查看用户信息 if [ $? [0-9]) echo "你输入的是数字。" ;
Cannot use v-for on stateful component root elemen 报错如图提示： image Cannot use v-for on stateful component root element because it renders multiple elements.中文大致意思：不能在根元素（root element）使用 v-for，因为v-for是个循环体呈现多个元素，v-for在根元素上导致无法渲染。 代码如图： {{item.name}} 修改后代码： {{item.name}}
