Apache Tomcat 是特别为JAVA设计的开源WEB服务器，使用非常广泛。  
以下是CentOS7中安装Tomcat 8 的步骤教程：

# 系统要求 #

1.CentOS7  
2.可登陆的非root的ssh账号

### Step1 升级CentOS系统 ###

sudo yum install epel-release
    sudo yum update -y && sudo reboot

### Step2 安装JAVA ###

sudo yum install java-1.8.0-openjdk.x86_64

安装完毕后，运行`java -version` 将输出如下内容：

openjdk version "1.8.0_91"
    OpenJDK Runtime Environment (build 1.8.0_91-b14)
    OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

### Step3 新增Tomcat专用用户 ###

sudo groupadd tomcat
    sudo mkdir /opt/tomcat
    sudo useradd -s /bin/nologin -g tomcat -d /opt/tomcat tomcat

注意，用户目录是 `/opt/tomcat`

### Step4 下载并安装最新版本Tomcat ###

cd ~
    wget http://www-us.apache.org/dist/tomcat/tomcat-8/v8.0.33/bin/apache-tomcat-8.0.33.tar.gz
    sudo tar -zxvf apache-tomcat-8.0.33.tar.gz -C /opt/tomcat --strip-components=1

### Step5 权限设置 ###

cd /opt/tomcat
    sudo chmod -R tomcat .
    sudo chgrp -R tomcat conf
    sudo chmod g+rwx conf
    sudo chmod g+r conf/*
    sudo chown -R tomcat logs/ temp/ webapps/ work/

### Step6 为Tomcat创建systemd unit 文件 ###

sudo vi /etc/systemd/system/tomcat.service

内容如下：

[Unit]
    Description=Apache Tomcat Web Application Container
    After=syslog.target network.target
    
    [Service]
    Type=forking
    
    Environment=JAVA_HOME=/usr/lib/jvm/jre
    Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid
    Environment=CATALINA_HOME=/opt/tomcat
    Environment=CATALINA_BASE=/opt/tomcat
    Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
    Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'
    
    ExecStart=/opt/tomcat/bin/startup.sh
    ExecStop=/bin/kill -15 $MAINPID
    
    User=tomcat
    Group=tomcat
    
    [Install]
    WantedBy=multi-user.target

### Step7 安装haveged ###

sudo yum install haveged
    sudo systemctl start haveged.service
    sudo systemctl enable haveged.service

### Step8 启动Tomcat 并开启防火墙 ###

sudo systemctl start tomcat.service
    sudo systemctl enable tomcat.service
    
    sudo firewall-cmd --zone=public --permanent --add-port=8080/tcp
    sudo firewall-cmd --reload

访问 `http://[Your-Host-IP]:8080` 预览是否正常。

### Step9 配置Tomcat 管理界面 ###

sudo vi /opt/tomcat/conf/tomcat-users.xml

在 `<tomcat-users ...>...</tomcat-users>`中加入一个admin账号：

之后重启Tomcat

sudo systemctl restart tomcat.service
