2. 操作系统检查
Tomcat 10.1支持RHEL 7.3+、RHEL 8.0+、RHEL 9.0+等操作系统。本文以RHEL 9为例。学习交流加群风哥微信: itpux-com
# cat /etc/redhat-release
Red Hat Enterprise Linux release 9.0 (Plow)
# 检查内核版本
# uname -r
5.14.0-70.22.1.el9_0.x86_64
# 检查SELinux状态
# getenforce
Disabled
# 关闭SELinux（如未关闭）
# vi /etc/selinux/config
SELINUX=disabled
# 检查防火墙状态
# systemctl status firewalld
# 关闭防火墙（生产环境建议开放特定端口而非完全关闭）
# systemctl stop firewalld
# systemctl disable firewalld
3. 安装准备
在安装Tomcat之前，需要进行一系列准备工作，包括安装Java JDK、创建用户和组、配置网络等。
sudo dnf install java-11-openjdk-devel -y
# 设置JAVA_HOME环境变量
echo “export JAVA_HOME=$(dirname $(dirname $(readlink $(readlink $(which javac))))” >> ~/.bashrc
echo “export PATH=$JAVA_HOME/bin:$PATH” >> ~/.bashrc
source ~/.bashrc
# 验证Java安装
# java -version
openjdk version “11.0.16” 2022-07-19
OpenJDK Runtime Environment (Red_Hat-11.0.16.0.8-1.el9_0)
OpenJDK 64-Bit Server VM (Red_Hat-11.0.16.0.8-1.el9_0, mixed mode, sharing)
# 配置防火墙例外（如果防火墙开启）
sudo firewall-cmd –permanent –add-port=8080/tcp
sudo firewall-cmd –permanent –add-port=8443/tcp
sudo firewall-cmd –reload
4. Tomcat软件安装
现在开始安装Tomcat 10.1软件，按照以下步骤进行。
sudo useradd -m -U -d /opt/tomcat -s /bin/false tomcat
# 下载Tomcat 10.1
cd /tmp
sudo wget https://archive.apache.org/dist/tomcat/tomcat-10/v10.1.0/bin/apache-tomcat-10.1.0.tar.gz
# 解压安装包
sudo tar -xzf apache-tomcat-10.1.0.tar.gz -C /opt/tomcat/
# 创建符号链接
sudo ln -s /opt/tomcat/apache-tomcat-10.1.0 /opt/tomcat/latest
# 设置权限
sudo chown -R tomcat:tomcat /opt/tomcat/
5. Tomcat配置
配置Tomcat服务，包括创建systemd服务文件、配置JVM参数等。
sudo vi /etc/systemd/system/tomcat.service
# 内容如下

6. 测试验证
验证Tomcat服务是否正常运行，包括访问默认页面和管理控制台。学习交流加群风哥QQ113257174
# netstat -tuln | grep 8080
tcp6 0 0 :::8080 :::* LISTEN
# 访问Tomcat默认页面
# curl -I http://localhost:8080
HTTP/1.1 200 OK

7. 备份配置
配置Tomcat备份策略，确保配置文件和Web应用的安全。
mkdir -p /backup/tomcat
# 执行备份
# 备份配置文件
cp -r /opt/tomcat/latest/conf /backup/tomcat/
# 备份Web应用
cp -r /opt/tomcat/latest/webapps /backup/tomcat/
# 验证备份文件
ls -la /backup/tomcat/
drwxr-xr-x 4 root root 4096 Mar 31 10:20 .
drwxr-xr-x 3 root root 4096 Mar 31 10:15 ..
drwxr-xr-x 3 root root 4096 Mar 31 10:20 conf
drwxr-xr-x 4 root root 4096 Mar 31 10:20 webapps
# 创建备份脚本
vi /root/backup_tomcat.sh
#!/bin/bash
DATE=$(date +%Y%m%d)
BACKUP_DIR=”/backup/tomcat”
# 创建备份目录（如果不存在）
mkdir -p $BACKUP_DIR
# 执行备份
cp -r /opt/tomcat/latest/conf $BACKUP_DIR/conf_$DATE
cp -r /opt/tomcat/latest/webapps $BACKUP_DIR/webapps_$DATE
# 保留最近7天的备份
find $BACKUP_DIR -name “conf_*.” -mtime +7 -delete
find $BACKUP_DIR -name “webapps_*.” -mtime +7 -delete
# 给脚本添加执行权限
chmod +x /root/backup_tomcat.sh
# 添加到crontab
crontab -e
# 添加以下内容（每天凌晨2点执行备份）
