Linux基本得命令和软件基础

登录阿里云并购买服务器 进入阿里云官网

[https://www.aliyun.com][https_www.aliyun.com]

尽量选择系统镜像,并且选择CentOS7的镜像文件

搭建自己得web程序

点详情进入服务器  
包含了一些基本信息,主要是公网IP和内网IP

左侧的导航栏远程连接,点击密钥管理  
新建一个密钥,新建完密钥之后会有一个文件要你下载,此文件相当重要,而且只能下载一次,妥善保管,使用自动生成的密钥

生成完之后,点击查看密钥指纹,可以查看自己的密钥

设置第三步的管理员密码  
远程连接工具  
阿里云推荐的是使用putty

工具是xshell  
远程文件上传工具xftp

mysql的安装:

在linux上下载文件需要先安装wget

yum -y install wget

如果没有安装wget，会出现-bash:wget:未找到命令

获取安装包

wget [https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm][https_dev.mysql.com_get_mysql57-community-release-el7-11.noarch.rpm]

安装mysql源

yum -y localinstall mysql57-community-release-el7-11.noarch.rpm

在线安装Mysql

yum -y install mysql-community-server

启动Mysql服务  
systemctl start mysqld

设置开机启动  
systemctl enable mysqld  
systemctl daemon-reload

查看临时密码:  
方法一:grep ‘temporary password’ /var/log/mysqld.log

方法二:vi /var/log/mysqld.log

必须修改密码:  
ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘root’;

密码太简单,需要执行以下两条命令

修改validate\_password\_policy参数的值  
set global validate\_password\_policy=0;  
再修改密码的长度  
set global validate\_password\_length=1;  
再次执行修改密码就可以了  
ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘root’;

远程连接  
设置远程连接权限  
grant all privileges on *.* to root@’%’ identified by “root”;  
刷新更改  
flush privileges;

开启防火墙:  
通过systemctl status firewalld查看firewalld状态，发现当前是dead状态，即防火墙未开启。  
通过systemctl start firewalld开启防火墙，没有任何提示即开启成功。  
再次通过systemctl status firewalld查看firewalld状态，显示running即已开启了。  
如果要关闭防火墙设置，可能通过systemctl stop firewalld这条指令来关闭该功能。  
再次执行执行firewall-cmd --permanent --zone=public --add-port=3306/tcp，提示success，表示设置成功，这样就可以继续后面的设置了。

通过iptables开启防火墙

iptables服务安装命令:  
yum install iptables-services  
开启iptables防火墙命令:  
systemctl start iptables.service  
重启iptables防火墙的命令:  
systemctl restart iptables.service  
关闭iptables防火墙的命令:  
systemctl stop iptables.service  
查看iptables防火墙状态的命令:  
systemctl status iptables.service  
设置iptables防火墙开机启动:  
systemctl enable iptables.service  
开放3306端口  
/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT  
添加后进行保存-------service iptables save

检测jdk安装包  
rpm -qa | grep java

卸载(有的话，没有跳过)  
假设有java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86\_64  
rpm -e --nodeps  
java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86\_64  
再次检测

上传jdk，解压  
tar -zxvf jdk-8u171-linux-x64.tar.gz

配置环境变量

1)vi /etc/profile  
2)配置环境变量  
JAVA\_HOME=/usr/java/jdk1.8.0\_171  
CLASSPATH= J A V A H O M E / l i b / P A T H = JAVA\_HOME/lib/ PATH= JAVAHOME/lib/PATH=PATH:$JAVA\_HOME/bin  
export PATH JAVA\_HOME CLASSPATH

重新加载文件  
source /etc/profile  
测试  
java -version

Tomcat的安装  
1.将tomcat-linux上传到Linux  
2.解压tomcat: tar -zxvf apache-tomcat-7.0.88.tar.gz  
3.如果没有开放8080端口，需要在防火墙配置文件中开放8080端口,  
4.或者直接使用命令添加8080端口：firewall-cmd --zone=public --add-port=8080/tcp --permanent  
5.systemctl restart firewalld.service  
6.也可以通过iptables添加端口,/sbin/iptables -I INPUT -p tcp --dport 8080 -j ACCEPT,然后添加后进行保存-------service iptables save  
7.启动tomcat服务 ./startup.sh 停止服务:./shutdown.sh
