$ /usr/local/nginx/sbin/nginx: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or directory
从报错内容看是找不到libssl.so.0.9.8
如何解决？
1. 通过ldd查找缺少的库
$ ldd $(which /usr/local/nginx/sbin/nginx) linux-gate.so.1 => (0xb7773000) libcrypt.so.1 => /lib/i386-linux-gnu/libcrypt.so.1 (0xb7729000) libpcre.so.3 => /lib/i386-linux-gnu/libpcre.so.3 (0xb76ea000) libssl.so.0.9.8 => not found libcrypto.so.0.9.8 => not found libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xb76e4000) libz.so.1 => /lib/i386-linux-gnu/libz.so.1 (0xb76cf000) libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb7553000) /lib/ld-linux.so.2 (0xb7774000)
2.进入/lib/i386-linux-gnu/ 目录，发现原来是libssl.so.0.9.8 libcrypto.so.0.9.8 这两个文件升级成
libssl.so.1.0.0 libcrypto.so.1.0.0 导致，
做软链接没办法解决依赖关系，此时最好是重新编译niginx，使用升级后的库。
$ ldd $(which /usr/local/nginx/sbin/nginx) linux-gate.so.1 => (0xb77b8000) libcrypt.so.1 => /lib/i386-linux-gnu/libcrypt.so.1 (0xb776e000) libpcre.so.3 => /lib/i386-linux-gnu/libpcre.so.3 (0xb772f000) libssl.so.1.0.0 => /lib/i386-linux-gnu/libssl.so.1.0.0 (0xb76e1000) libcrypto.so.1.0.0 => /lib/i386-linux-gnu/libcrypto.so.1.0.0 (0xb753d000) libz.so.1 => /lib/i386-linux-gnu/libz.so.1 (0xb7528000) libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb73ac000) libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xb73a7000) /lib/ld-linux.so.2 (0xb77b9000)
