libmysqlclient.so.18: cannot open shared object file: No such file or directory，sharedobject

<span style="font-size:24px;">錯誤情形：</span>

[root@localhost ~]# /usr/local/nagios/libexec/check_mysql -h/usr/local/nagios/libexec/check_mysql: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory

解決方案：當然是針對我的虛擬機器情形

利用命令 ：[root@238-lamp ld.so.conf.d]#  find / -name libmysqlclient.so.18
/usr/local/mysql/lib/libmysqlclient.so.18
/home/oldboy/tools/mysql-5.6.10/libmysql/libmysqlclient.so.18

將/usr/local/mysql/lib（mysql的安裝目錄）路徑加到/etc/ld.so.conf中

[root@238-lamp ld.so.conf.d]# vi /etc/ld.so.conf                       include ld.so.conf.d/*.conf/usr/local/lib/usr/local/mysql/lib~~~"/etc/ld.so.conf" 4L, 90C written[root@238-lamp ld.so.conf.d]# ldconfig（生效命令）       [root@238-lamp ld.so.conf.d]# /usr/local/nagios/libexec/check_mysql -hcheck_mysql v1.4.16 (nagios-plugins 1.4.16)Copyright (c) 1999-2007 Nagios Plugin Development Team        <nagiosplug-devel@lists.sourceforge.net>This program tests connections to a MySQL serverUsage: check_mysql [-d database] [-H host] [-P port] [-s socket]       [-u user] [-p password] [-S]Options: -h, --help    Print detailed help screen -V, --version    Print version information -H, --hostname=ADDRESS    Host name, IP Address, or unix socket (must be an absolute path) -P, --port=INTEGER    Port number (default: 3306) -s, --socket=STRING    Use the specified socket (has no effect if -H is used) -d, --database=STRING    Check database with indicated name -u, --username=STRING    Connect using the indicated username -p, --password=STRING
