php gd库没有安装问题确认

今天一个php开发找上门，说某台服务器gd库用不了

看看编译用的gd库路径是/usr/local/gd

/usr/local/php/bin/php-config |grep --color=auto gd

  --ldflags           [ -L/usr/kerberos/lib64 -L/usr/local/lib -L/usr/local/libjpeg/lib -L/usr/local/libpng/lib -L/usr/local/freetype/lib -L/usr/local/gd/lib -L/usr/local/mysql/lib]

  --libs              [-lcrypt   -lz -lcrypt -lmysqlclient -lmcrypt -lltdl -lgd -lfreetype -lpng -lz -ljpeg -lcurl -lbz2 -lz -lrt -lm -ldl -lnsl  -lrt -lxml2 -lz -lm -lssl -lcrypto -ldl -lz -lcurl -lidn -lssl -lcrypto -lrt -lssl -lcrypto -ldl -lz -lz -lxml2 -lz -lm -lssl -lcrypto -ldl -lz -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt -lxml2 -lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt ]

ldd查看lib文件用的路径，发现gd 用的lib是

ldd /usr/local/php/bin/php|grep jp

libjpeg.so.7 => /usr/local/libjpeg/lib/libjpeg.so.7 (0x00002b5541e18000)

libjpeg.so.62 => /usr/lib64/libjpeg.so.62 (0x00002b5542f1c000)

ldd /usr/local/php/bin/php|grep gd

libgd.so.2 => /usr/lib64/libgd.so.2 (0x00002b8dc7002000)

md5和ll查看是否为同一个文件

md5sum /usr/lib64/libgd.so.2

a4d9246143fc28542bea0774c073c863  /usr/lib64/libgd.so.2

ll /usr/lib64/libgd.so.2          

lrwxrwxrwx 1 root root 14 Jul 31  2014 /usr/lib64/libgd.so.2 -> libgd.so.2.0.0

 ll /usr/local/gd/lib/libgd.

libgd.a         libgd.la        libgd.so        libgd.so.2      libgd.so.2.0.0  

ll /usr/local/gd/lib/libgd.so.2  

lrwxrwxrwx 1 root root 14 May 15 10:20 /usr/local/gd/lib/libgd.so.2 -> libgd.so.2.0.0

md5sum /usr/local/gd/lib/libgd.so.2

cdb329af5b013d40d79f29f02ba1b275  /usr/local/gd/lib/libgd.so.2

明显不一致，所以只能重新编译php
