本次使有4臺主機，系統均為centos7，1臺nignx，2臺tomcat，1臺nfs

第一臺配置nignx腳本

}
EOFsleep 5# 啟動Nginx
systemctl start nginx && systemctl enable nginx
if [ $? = 0 ]
then echo "成功"elseecho "失敗"exit 0
fi

tomcat配置腳本，2臺都是一樣的配置，這里非常注意創建的安裝目錄，后面啟動腳本在里面，要指定絕對路徑

#!/bin/bash
#nignx+Tomcat+NFS負載均衡加共享儲存服務腳本，4臺服務器centos7
#本腳本為tomcat腳本
#xiexianghu   2025.6.23#關閉防火墻和selinux

sleep 5ip=$(hostname  -I  |awk  '{print  $1}')# 安裝OpenJDK 8
yum install -y java-1.8.0-openjdk java-1.8.0-openjdk-devel
if [ $? = 0 ]
thenecho "安裝成功"
elseecho "安裝失敗"sleep 5exit 1  # 返回非零狀態碼表示失敗
fi# 驗證安裝
java -version# 創建安裝目錄
cd /usr/local# 下載Tomcat 9（可根據需求選擇版本）
wget https://dlcdn.apache.org/tomcat/tomcat-9/v9.0.105/bin/apache-tomcat-9.0.105.tar.gz

tar -zxvf apache-tomcat-9.0.105.tar.gz
if [[ $? -ne 0 ]]; thenecho "解壓Tomcat失敗"exit 1

mv apache-tomcat-9.0.105 tomcat
chmod -R 755 /usr/local/tomcat#配置 Tomcat 標識

nfs配置腳本

#!/bin/bash
#nignx+Tomcat+NFS負載均衡加共享儲存服務腳本，4臺服務器centos7
#本腳本為NFS腳本
#xiexianghu   2025.6.23#安裝 NFS 服務
#使用yum命令安裝rpcbind和nfs-utils
yum -y install rpcbind nfs-utils#創建共享目錄
mkdir /data/
mkdir /data/share/
chmod 755 -R /data/share/#編輯 NFS 的配置文件/etc/exports，添加共享目錄及權限設置
# 配置NFS共享
echo "正在配置NFS共享..."
# 檢查/etc/exports文件是否存在，若不存在則創建
if [ ! -f /etc/exports ]; thentouch /etc/exports
fi# 向exports文件中添加共享配置
echo "/data/share/ 10.10.10.104(rw,no_root_squash,no_all_squash,sync)" >> /etc/exports
echo "/data/share/ 10.10.10.105(rw,no_root_squash,no_all_squash,sync)" >> /etc/exports# 重新導出NFS共享
echo "正在重新導出NFS共享..."
exportfs -r# 啟動NFS相關服務
echo "正在啟動NFS相關服務..."
systemctl start rpcbind
systemctl start nfs# 設置服務開機自啟
echo "正在設置服務開機自啟..."
systemctl enable rpcbind
systemctl enable nfs# 輸出腳本執行完成信息
echo "NFS服務安裝與配置完成！"

最后解釋tomcat的最后配置腳本

#!/bin/bash# NFS客戶端配置與掛載腳本
# 功能：安裝NFS客戶端工具，創建掛載目錄，配置NFS掛載并設置開機自動掛載
# 輸出腳本開始信息
echo "開始配置NFS客戶端..."# 安裝NFS相關服務
echo "正在安裝rpcbind和nfs-utils..."
yum -y install rpcbind
yum -y install nfs-utils# 創建掛載目錄
echo "正在創建掛載目錄..."
mkdir -p /mnt/share# 臨時掛載NFS共享
echo "正在臨時掛載NFS共享..."
mount -t nfs 10.10.10.100:/data/share /mnt/share/ -o nolock,nfsvers=3,vers=3# 配置開機自動掛載
echo "正在配置開機自動掛載..."
# 檢查rc.local文件是否存在，不存在則創建
if [ ! -f /etc/rc.d/rc.local ]; thentouch /etc/rc.d/rc.localchmod +x /etc/rc.d/rc.local
fi
# 向rc.local中添加掛載命令（避免重復添加）
grep -q "mount -t nfs 10.10.10.100:/data/share /mnt/share/ -o nolock,nfsvers=3,vers=3" /etc/rc.d/rc.local
if [ $? -ne 0 ]; thenecho "mount -t nfs 10.10.10.100:/data/share /mnt/share/ -o nolock,nfsvers=3,vers=3" >> /etc/rc.d/rc.local
fi# 確保rc.local有執行權限
chmod +x /etc/rc.d/rc.local# 輸出腳本執行完成信息
echo "NFS客戶端配置與掛載完成！"
echo "當前已臨時掛載NFS共享，系統重啟后將自動掛載。"

全部配置好后在tomcat1中創建文件，在tomcat2中會同步
