postfix start error!

Do you have that library installed? If not install it. If it is installed, make sure you have at least a symlink to the expected library location...

Hi!Scott!

Thanks for your comment.
Of course the library is installed.
If possible, I do not want to use symlink ... Does not there any other means ...

Since you define LD_LIBRARY_PATH MAKE SURE to include /usr/lib:/usr/local/lib
Not sure why you are running postfix out of /var/ap/home versus the normal /usr/sbin ..

What Linux distribution are you running, are you using some kind of prepared package ......?

Hi!arnold!
Thanks for your comment.

>Since you define LD_LIBRARY_PATH MAKE SURE to include /usr/lib:/usr/local/lib
I set it to LD_LIBRARY_PATH, but the result does not change.
Also, setting the path to OpenSSL in ld.so.conf.d will work.

>Not sure why you are running postfix out of /var/ap/home versus the normal /usr/sbin ..
Due to security concerns, I have installed OpenSSL and installed it in a different location than usual.
The place where OpenSSL is installed is "var / home / lib / openssl".

Also, in Postfix build, I compile using the following command, is this correct?
make -f Makefile.init makefiles \
        shared=yes \
        dynamicmaps=yes \
        command_directory=/var/home/ap/postfix/bin \
        config_directory=/var/home/ap/postfix/etc \
        daemon_directory=/var/home/ap/postfix/libexec \
        data_directory=/var/home/ap/postfix/data \
        mailq_path=/var/home/ap/postfix/bin/mailq \
        manpage_directory=/var/home/ap/postfix/man \
        meta_directory=/var/home/ap/postfix/etc \
        newaliases_path=/var/home/ap/postfix/bin/newaliases \
        openssl_path=/var/home/lib/openssl/bin/openssl \
        queue_directory=/var/home/ap/postfix/queue \
        sendmail_path=/var/home/ap/postfix/bin/sendmail \
        shlib_directory=/var/home/ap/postfix/lib \
        OPT='-O2 -march=corei7-avx -mtune=atom -fno-strict-aliasing' \
        CCARGS='-DHAS_SSL -DUSE_TLS -DHAS_PCRE -I/var/home/lib/openssl/include/openssl' \
        AUXLIBS='-L/var/home/lib/openssl/lib -lssl -lcrypto -lpcre -ldl -lz'

Please help someone.

What security concerns? If you are running postfix chrooted, you have to make sure that everything is in the path.Check what your /etc/ld.so.conf
run ldconfig /var/home/lib /var/home/lib/openssl/ /var/home/lib/openssl/lib
/etc/ld.so.conf and /etc/ld.so.conf.d/* you may have to add references to the openssl as /var/home/lib as a path where libraries can be found.

In a situation where you compile you programs, you would have to keep an eye on vulnerabilities and patch them yourself versus relying on Centos updates that manage the updates while maintaining the major/minor version of the programs to avoid any changes in functionality/behavior.

Hi!arnold!
Thanks for your comment.

I do not use chroot.

Is there only using 'ld.so.conf'?
Can I make a dynamic link with "LD_LIBRARY_PATH"?

Please help someone.

Thanks!

glad I could help, if you decide to compile apps from source, you might want to consider installing them in /usr/local as the path
sysconfdir=/etc/
systemstatedir=/var/
sendmail_ref=/usr/sbin/sendmail or make sure the symlink for /etc/alternatives/mta to maintain other apps that might use sendmail..

You can build your own RPM packages...... .and then install/remove/update them...
placing apps in /home could be an issue if you ever mount /home as nosuid, and other parameters.
