用mysql命令登录的时候报错:
[[email protected] www]# mysql -uroot -p mysql: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory
搜索 libmysqlclient.so.16 但是没有找到这个文件
[[email protected] www]# locate libmysqlclient.so /data/db_include/mysql5.7/lib/libmysqlclient.so /data/db_include/mysql5.7/lib/libmysqlclient.so.20 /data/db_include/mysql5.7/lib/libmysqlclient.so.20.3.4 [[email protected] www]# locate libmysqlclient.so.16 [[email protected] www]# locate libmysqlclient.so.16
网上下载了一个 libmysqlclient.so.16 64位的放在了/usr/lib64目录下 下载地址
[[email protected] www]# rpm -qa | grep Percona [[email protected] www]# ldd /usr/bin/mysql /usr/bin/mysql: /usr/lib64/libmysqlclient.so.16: no version information available (required by /usr/bin/mysql) linux-vdso.so.1 => (0x00007ffd753d8000) libncursesw.so.5 => /lib64/libncursesw.so.5 (0x00007f4d9a17e000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f4d99f60000) libmysqlclient.so.16 => /usr/lib64/libmysqlclient.so.16 (0x00007f4d99b03000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007f4d998cc000) libnsl.so.1 => /lib64/libnsl.so.1 (0x00007f4d996b2000) libssl.so.10 => /usr/lib64/libssl.so.10 (0x00007f4d99446000) libcrypto.so.10 => /usr/lib64/libcrypto.so.10 (0x00007f4d99061000) libz.so.1 => /lib64/libz.so.1 (0x00007f4d98e4a000) libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007f4d98b44000) libm.so.6 => /lib64/libm.so.6 (0x00007f4d988c0000) libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f4d986a9000) libc.so.6 => /lib64/libc.so.6 (0x00007f4d98315000) libtinfo.so.5 => /lib64/libtinfo.so.5 (0x00007f4d980f4000) libdl.so.2 => /lib64/libdl.so.2 (0x00007f4d97eef000) /lib64/ld-linux-x86-64.so.2 (0x00007f4d9a3b2000) librt.so.1 => /lib64/librt.so.1 (0x00007f4d97ce7000) libfreebl3.so => /lib64/libfreebl3.so (0x00007f4d97ae4000) libgssapi_krb5.so.2 => /lib64/libgssapi_krb5.so.2 (0x00007f4d9789f000) libkrb5.so.3 => /lib64/libkrb5.so.3 (0x00007f4d975b8000) libcom_err.so.2 => /lib64/libcom_err.so.2 (0x00007f4d973b4000) libk5crypto.so.3 => /lib64/libk5crypto.so.3 (0x00007f4d97187000) libkrb5support.so.0 => /lib64/libkrb5support.so.0 (0x00007f4d96f7c000) libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x00007f4d96d78000) libresolv.so.2 => /lib64/libresolv.so.2 (0x00007f4d96b5e000) libselinux.so.1 => /lib64/libselinux.so.1 (0x00007f4d9693f000)
继续登录发现还是报错
[[email protected] www]# mysql mysql: /usr/lib64/libmysqlclient.so.16: no version information available (required by mysql) mysql: relocation error: mysql: symbol disabled_my_option, version libmysqlclient_16 not defined in file libmysqlclient.so.16 with link time reference
最后解决方法:
原来是以前的文件/usr/bin/mysql没替换的原因
用以下二条命令搞定了。
cd /usr/bin mv mysql mysql.rpmbak ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql
再次登录:
[[email protected] bin]# mysql ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: NO)
