解压deb包添加脚本
dpkg-deb -R openssh-local_10.2p1-1_amd64.deb tmp/
cd tmp
1️⃣ DEBIAN/postinst（安装后执行）
#!/bin/bash
set -e
echo 'export LD_LIBRARY_PATH=/usr/local/lib64${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}' > /etc/profile.d/openssl-local.sh
source /etc/profile
echo "==> 已将/usr/local/lib64加入到LD_LIBRARY_PATH动态链接库"
echo "==> openssl-local_3.5.4-1已安装完成"
exit 0
2️⃣ DEBIAN/postrm（卸载后执行）
#!/bin/bash
set -e
rm -rf /etc/profile.d/openssl-local.sh
source /etc/profile
exit 0
🔐 设置脚本权限
chmod 755 DEBIAN/{postinst,postrm}
📦 重新打包deb文件
dpkg-deb -b tmp/ openssl-local_3.5.4-1_amd64.deb
