Centos7下Tomcat环境安装及使用脚本安装

一、安装Java
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)
二、添加tomcat用户
groupadd tomcat
useradd -s /bin/nologin -g tomcat -d /usr/local/tomcat tomcat
三、下载Tomcat
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 /usr/local/tomcat --strip-components=1
cd /usr/local/tomcat
chown -R tomcat .
chgrp -R tomcat conf
chmod g+rwx conf
chmod g+r conf/*
chown -R tomcat logs/ temp/ webapps/ work/
四、为Tomcat创建systemd unit 文件
vi /etc/systemd/system/tomcat.service
[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

五、 安装haveged
yum install haveged
systemctl start haveged.service && systemctl enable haveged.service
六、启动Tomcat 并开启防火墙
systemctl start tomcat.service && systemctl enable tomcat.service
firewall-cmd --zone=public --permanent --add-port=8080/tcp && firewall-cmd --reload
访问 http://[Your-Host-IP]:8080 预览是否正常。
七、配置Tomcat 管理界面
vi /usr/local/tomcat/conf/tomcat-users.xml
在 <tomcat-users ...>...</tomcat-users>中加入一个admin账号：
<user username="yourusername" password="yourpassword" roles="manager-gui,admin-gui"/>
重启Tomcat

sudo systemctl restart tomcat.service

附脚本

#!/usr/bin/env bash
yum install java-1.8.0-openjdk.x86_64
groupadd tomcat && mkdir /usr/local/tomcat &&\
useradd -s /bin/nologin -g tomcat -d /usr/local/tomcat tomcat
wget -c http://mirrors.shu.edu.cn/apache/tomcat/tomcat-8/v8.5.31/bin/apache-tomcat-8.5.31.tar.gz &&\
tar -zxvf apache-tomcat-8.5.31.tar.gz -C /usr/local/ && cd /usr/local/ &&\
mv apache-tomcat-8.5.31 tomcat && cd tomcat &&\
chown -R tomcat . && chgrp -R tomcat conf && chmod g+rwx conf && chmod g+r conf/*
touch /etc/systemd/system/tomcat.service
#将一下代码添加到tomcat.service上去
cat>>/etc/systemd/system/tomcat.service<<EOF
