如何将程序依赖的动态库拷贝到指定的目录？
1、通过LDD查看依赖的动态库。
# ldd postgres linux-vdso.so.1 => (0x00007ffcfc324000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fb6151ba000) libxml2.so.2 => /lib64/libxml2.so.2 (0x00007fb614e4f000) libpam.so.0 => /lib64/libpam.so.0 (0x00007fb614c40000) libssl.so.10 => /lib64/libssl.so.10 (0x00007fb6149ce000) libcrypto.so.10 => /lib64/libcrypto.so.10 (0x00007fb61456c000) libgssapi_krb5.so.2 => /lib64/libgssapi_krb5.so.2 (0x00007fb61431f000) librt.so.1 => /lib64/librt.so.1 (0x00007fb614117000) libdl.so.2 => /lib64/libdl.so.2 (0x00007fb613f12000) libm.so.6 => /lib64/libm.so.6 (0x00007fb613c10000) libldap-2.4.so.2 => /lib64/libldap-2.4.so.2 (0x00007fb6139bc000) libicui18n.so.50 => /lib64/libicui18n.so.50 (0x00007fb6135bc000) libicuuc.so.50 => /lib64/libicuuc.so.50 (0x00007fb613243000) libsystemd.so.0 => /lib64/libsystemd.so.0 (0x00007fb61321b000) libc.so.6 => /lib64/libc.so.6 (0x00007fb612e59000) /lib64/ld-linux-x86-64.so.2 (0x00007fb6153e1000) libz.so.1 => /lib64/libz.so.1 (0x00007fb612c43000) liblzma.so.5 => /lib64/liblzma.so.5 (0x00007fb612a1d000) libaudit.so.1 => /lib64/libaudit.so.1 (0x00007fb6127f4000) libkrb5.so.3 => /lib64/libkrb5.so.3 (0x00007fb61250c000) libcom_err.so.2 => /lib64/libcom_err.so.2 (0x00007fb612308000) libk5crypto.so.3 => /lib64/libk5crypto.so.3 (0x00007fb6120d4000) libkrb5support.so.0 => /lib64/libkrb5support.so.0 (0x00007fb611ec6000) libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x00007fb611cc2000) libresolv.so.2 => /lib64/libresolv.so.2 (0x00007fb611aa7000) liblber-2.4.so.2 => /lib64/liblber-2.4.so.2 (0x00007fb611898000) libsasl2.so.3 => /lib64/libsasl2.so.3 (0x00007fb61167b000) libssl3.so => /lib64/libssl3.so (0x00007fb61142e000) libsmime3.so => /lib64/libsmime3.so (0x00007fb611207000) libnss3.so => /lib64/libnss3.so (0x00007fb610edd000) libnssutil3.so => /lib64/libnssutil3.so (0x00007fb610caf000) libplds4.so => /lib64/libplds4.so (0x00007fb610aab000) libplc4.so => /lib64/libplc4.so (0x00007fb6108a6000) libnspr4.so => /lib64/libnspr4.so (0x00007fb610667000) libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007fb61035f000) libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007fb610149000) libicudata.so.50 => /lib64/libicudata.so.50 (0x00007fb60eb74000) libcap.so.2 => /lib64/libcap.so.2 (0x00007fb60e96f000) libselinux.so.1 => /lib64/libselinux.so.1 (0x00007fb60e748000) libgcrypt.so.11 => /lib64/libgcrypt.so.11 (0x00007fb60e4c6000) libgpg-error.so.0 => /lib64/libgpg-error.so.0 (0x00007fb60e2c1000) libdw.so.1 => /lib64/libdw.so.1 (0x00007fb60e079000) libcap-ng.so.0 => /lib64/libcap-ng.so.0 (0x00007fb60de72000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007fb60dc3b000) libattr.so.1 => /lib64/libattr.so.1 (0x00007fb60da35000) libpcre.so.1 => /lib64/libpcre.so.1 (0x00007fb60d7d3000) libelf.so.1 => /lib64/libelf.so.1 (0x00007fb60d5bb000) libbz2.so.1 => /lib64/libbz2.so.1 (0x00007fb60d3aa000) libfreebl3.so => /lib64/libfreebl3.so (0x00007fb60d1a7000)
2、写一个SHELL脚本，自动拷贝依赖的动态库。
vi test.sh deplist=$( ldd $1 | awk '{if (match($3,"/")){ print $3}}' ) cp -L -n $deplist $2 -L 表示拷贝文件（如果是软链，会拷贝到最终的文件）。 -n 表示不覆盖已有文件。
3、创建目标目录。
mkdir /tmp/lib
4、将postgres依赖的动态库拷贝到目标目录
. ./test.sh /usr/pgsql-10/bin/postgres /tmp/lib/
