全新开始CentOS 8.2（二）：配置生产环境（JDK1.8+Tomcat9+nginx1.18+Mysql5.7）

sudo dnf install -y java-1.8.0-openjdk   #直接安装，简单

java -version   #验证版本

sudo useradd -m -U -d /opt/tomcat -s /bin/false tomcat #创建tomcat专用用户，无登录权限

sudo mkdir /opt/tomcat  #创建安装文件夹

cd ~/Download  #习惯了win时期的下载目录

wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.39/bin/apache-tomcat-9.0.39.zip

unzip apache-tomcat-9.0.39.zip   #解压

sudo mv apache-tomcat-9.0.39/ /opt/tomcat

sudo chown -R tomcat:tomcat tomcat/  #更改目录权限

sudo sh -c 'chmod +x /opt/tomcat/bin/*.sh'  #赋予执行权限

groupadd nginx  #创建专用组

useradd -g nginx -s /sbin/nologin -M nginx   #无登录专用用户

#-g:指定所属的group

#-s:指定shell,因为它不需要登录，所以用/sbin/nologin

#-M：不创建home目录,因为它不需要登录
