Error while loading shared libraries: libiconv. so.2

An error occurred while debugging zabbix recently:

/etc/init.d/zabbix_agentd start Starting zabbix_agentd:  /opt/program/zabbix/sbin/zabbix_agentd: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory                     [FAILED]

Cause analysis:

LD prompts that the library file cannot be found, and the library file is in the current directory.
The default directory of the linker LD is/lib and/usr/lib. If it is placed in another path, you need to let the LD know where the library file is.

 

Method 1:

Edit the/etc/lD. So. conf file and add the directory where the file is located in the new row;

Run ldconfig to update the/etc/lD. So. cache file;

Method 2:

Create a file with the. conf Suffix in the/etc/lD. So. conf. d/directory, and add the directory where the file is located to the file;

Run ldconfig to update the/etc/lD. So. cache file;

 

I think the second method is more convenient, with the minimum modification to the original system. Because the content of the/etc/lD. So. conf file is include/etc/lD. So. conf. d/*. conf. Therefore, any file added with the. conf suffix under the/etc/lD. So. conf. d/directory can be identified.

 

My practice:

1. put all the databases required by users to/usr/loca/LIB; 2. in/etc/lD. so. conf. d/directory to create a new file usr-libs.conf, the content is:/usr/local/lib 3. # sudo ldconfig

Update of LD. So. cache is incremental, just like the path system environment variable. Instead of re-establishing from scratch, the update is accumulated up.

Unless it is restarted, the LD. So. cache file is created from scratch.
