The main function of the Linux common command ldconfig command is to search the shared dynamic link library under the directory listed in the default search directory / lib and / usr/lib and the dynamic library configuration file / etc/ld.so.conf, and then create the connection and cache files needed by the dynamic loader (ld.so).

Syntax format: ldconfig [parameters]

Common parameters:-v displays the directory being scanned, the dynamic link library searched and the name of the connection created-n scans only the directory specified on the command line, not the default directory, nor the directory listed in the configuration file-N does not rebuild the cache file-X does not update the file connection-f CONF specifies that the configuration file of the dynamic link library is CONF The system defaults to / etc/ld.so.conf-C CACHE and specifies that the generated cache file is CACHE, and the default is / etc/ld.so.cache-r ROOT to change the root directory of the application to ROOT-l to enter expert mode to manually set the connection-p prints out the names of all shared libraries saved by the current cache file-c FORMAT specifies the format used by the cache file-V prints out the version information of ldconfig Then exit-- help prints out its help information, and then exits the reference instance to execute dynamic link library management commands:

[root@linux265 ~] # sudo ldconfig add library file / usr/local/mysql/lib to / etc/ld.so.conf file:

[root@linux265 ~] # echo "/ usr/local/mysql/lib" > > / etc/ld.so.conf [root@linux265 ~] # ldconfig-v | grep mysql "how to use the ldconfig command of Linux" ends here. Thank you for reading.
