postfixを起動しようとすると、次のエラーが発生します。
/usr/sbin/postconf: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such...r directory
/usr/bin/newaliases: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No suc...r directory
/usr/sbin/postfix: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No suc...r directory
Postfixはmysqlをインストールするまではうまくいきました。 mysqlでPostfixエラーが発生する理由が何であるかわかりません。
find . -name 'libmysqlclient*'コマンドを実行すると、次の結果が表示されます。
./usr/lib64/mysql/libmysqlclient.so.21

18バージョンがインストールされていませんが、なぜ21ではなく18を見つけるのか混乱しています。

誰でも助けることができますか？私の問題に似た他の記事をここで確認しましたが、試すのに十分な状況に近い解決策を見つけることができませんでした。

答え1
更新と修正:
この特定の問題を特定しようとして数時間努力した最後に、最終的にpostfixを削除して再インストールすることにしました。良いニュースは、この機能が機能し、失われたパッケージを見つけるのに役立ちます。
私が実行したコマンドは次のとおりです。
#yum remove postifix
#yum clean all
#yum install postfix
これでインストール結果は次のようになります。
# yum install postfix

最後に、次のコマンドを実行しました。
//Start Postfix
#systemctl start postfix
//Enable the service so it will start on its own after reboot
#systemctl enable postfix
//Check to ensure it is running with no errors
#systemctl status postfix
//The key portion of the output that I was looking for
Active: active (running)
最後に、正しく機能しているかどうかをテストしてみてください。もちろん、これは私のニーズに合わせてPostfixを設定した後です！
