可能用到的命令

1. 查看系统信息：cat /etc/redhat-release
2. 查看安装包：yum list xx*
3. 查看文件大小：du -h xxx或 du -b xxx
4. 从服务器上下载文件:scp username@servername:/remote_dir/filename local_dir
5. 上传本地文件到服务器:scp local_path/filename username@servername:remote_path
6. 从服务器下载整个目录:scp -r username@servername:/remote_dir/ local_dir
7. 上传目录到服务器:scp -r local_dir username@servername:remote_dir

安装环境

JDK

1. 查看jdk列表:yum list java*
2. 安装特定版本:yum -y install java-1.8.0-openjdk
3. 查看安装结果:java -v

MySql

安装

1. 查看系统版本

$ cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)

2. 下载对应的YUM https://dev.mysql.com/downloads/repo/yum/

$ wget https://dev.mysql.com/get/mysql80-community-release-el8-1.noarch.rpm

3. 安装MySql源

$ sudo rpm -Uvh mysql80-community-release-el8-1.noarch.rpm

4. 检查是否安装成功
   
   执行成功后会在/etc/yum.repos.d/目录下生成两个repo文件mysql-community.repo及 mysql-community-source.repo，并且通过yum repolist可以看到mysql相关资源

$ yum repolist enabled | grep "mysql.*-community.*"
!mysql-connectors-community/x86_64 MySQL Connectors Community                108
!mysql-tools-community/x86_64      MySQL Tools Community                      90
!mysql80-community/x86_64          MySQL 8.0 Community Server                113

5. 安装MySql
   
   下载比较慢

$ sudo yum install mysql-community-server

修改密码

$ ALTER USER 'root'@'localhost' IDENTIFIED BY 'xxxxxxxx

开启远程访问<8.0

$ grant all privileges on *.* to 'root'@'%' identified by '你的密码' with grant option

开启远程访问>=8.0

1. $ CREATE USER 'root'@'%' IDENTIFIED BY 'pWVRIVJw3NJX%%lB';
   
2. $ GRANT ALL ON *.* TO 'root'@'%';
3. $ ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'xxxxxx
4. $ FLUSH PRIVILEGES;

Tomcat

1. 现在本地下载Tomcat安装包
2. 上传到server
3. 解压安装包
4. 配置环境变量:

# Tomcat
export TOMCAT_HOME=/usr/local/apache-tomcat-9.0.35
export PATH=$TOMCAT_HOME/bin:$PATH

5. 增加域名解析conf/server.xml中Host节点添加新的Host

    <Host appBase="webapps" autoDeploy="true" name="easyplan.cloud" unpackWARs="true">
        <Alias>app.easyplan.cloud</Alias>
        <Context debug="0" path="" privileged="true" />
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
            pattern="%h %l %u %t" prefix="easyplan_access_log." resolveHosts="false"
            suffix=".txt" />
    </Host>

6. 启动：bin/start.sh
