ubuntu安装常用软件

作者:互联网

Ubuntu使用方法:

调整窗口大小:设备—安装增强功能

安装ifconfig: sudo apt-get install net-tools

更新:sudo apt update

安装mysql:

删除mysql的数据文件sudo rm /var/lib/mysql/ -R

删除mysql的配置文件sudo rm /etc/mysql/ -R

卸载mysql(包括server和client)

sudo apt-get autoremove mysql* --purge

sudo apt-get remove apparmor

然后在终端中查看MySQL的依赖项:dpkg --list|grep mysql

1、安装:sudo apt install mysql-server mysql-client
2、查看:sudo systemctl status mysql
安全操作:sudo mysql_secure_installation
3、安装依赖:sudo apt install libmysqlclient-dev
4、登入:sudo mysql  或者 mysql -u root -p 或者进入/etc/mysql目录下,查看debian.cnf文件可以看到初始账号密码

Mysql -u Debian-sys-maint -p …

5、use mysql;

6、修改密码

update user set authentication_string=PASSWORD("root")where user='root';
上面可能不适用mysql8
Alter user ‘root’@’localhost’ identified with mysql_native_password by ‘root’;
设置plugin字段
update user set plugin="mysql_native_password";

7、设置远程访问:

Use mysql;

select host,user from user;

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION

flush privileges;

quit

8、防火墙开放3306端口iptables -A INPUT -p tcp --dport 3306 -j ACCEPT

9、修改MySQL监听sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

10、#注释掉bind-address = 127.0.0.1

11、重启动MySQL

sudo /etc/init.d/mysql restart  或者 sudo service mysql restart

其他命令:

创建用户:CREATE USER 'username'@'host' IDENTIFIED BY 'password';
查看用户:SELECT User,Host FROM mysql.user;
用户授权:grant all on *.* to 'dimp'@'%' identified by '12345678';
查看密码策略SHOW VARIABLES LIKE 'validate_password%'
设置密码强度为lowset global validate_password_policy=LOW;

//添加个新的root主机是%

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';

报错:you are not allowed to create a user with grant

把localhost改为%

Update user set host=’%’ where user = ‘root’;

Grant all on *.* to ‘root’@’%’;这句要执行两次才成功。

user     = debian-sys-maint

password = UGh1OLt6VmpcAUkx

update user set authentication_string='' where user='root';

create user 'root'@'%' identified by 'root';

grant all on *.* to 'root'@'%';

alter user 'root'@'%' identified with mysql_native_password by 'root';

flush privileges;

 

防火墙管理:

sudo ufw disable 防火墙在系统启动时自动禁用

sudo ufw status 状态:不活动

~ sudo ufw enable 在系统启动时启用和激活防火墙

sudo ufw allow 81 规则已添加

sudo ufw deny 81 规则已更新

 

安装ssh

Sudo apt-get install openssh-server

 

安装telnet

安装openbsd-inetd

sudo apt-get install openbsd-inetd -y

安装telnetd
sudo apt-get install telnetd -y

重启openbsd-inetd
sudo /etc/init.d/openbsd-inetd restart

查看telnet运行状态
sudo netstat -a | grep telnet

登录

telnet 127.0.0.1(本机)

安装wireshark

Sudo apt-get install wireshark

Sudo usermod -aG wireshark 你的用户名
