安裝好sysbench后，試着打開時出錯：
[root@qht134 sysbench-master]# /usr/local/sysbench/bin/sysbench --version
/usr/local/sysbench/bin/sysbench: error while loading shared libraries: libmysqlclient.so.20: cannot open shared object file: No such file or directory
字面意思就是打不到共享庫文件libmysqlclient.so.20.
先查找一下本地有沒有這個文件：
[root@qht134 /]# find . -name 'libmysqlclient*' ./usr/lib64/mysql/libmysqlclient.so.16
./usr/lib64/mysql/libmysqlclient.so.16.0.0
./usr/lib64/mysql/libmysqlclient_r.so.16
./usr/lib64/mysql/libmysqlclient_r.so.16.0.0
./usr/local/mysql/lib/libmysqlclient.so.20
./usr/local/mysql/lib/libmysqlclient.so.20.3.8
./usr/local/mysql/lib/libmysqlclient.a
./usr/local/mysql/lib/libmysqlclient.so
在/usr/loca/mysql/lib下面有這個文件，解決方法是先建立一個軟鏈接到/usr/local/lib
[root@qht134 /]# ln -s /usr/local/mysql/lib/libmysqlclient.so.20 /usr/local/lib/libmysqlclient.so.20
接着在/etc/ld.so.cnf中加入/usr/loca/lib這一行
[root@qht134 /]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/lib
執行ldconfig -v更新下配置就可以了
[root@qht134 /]# /sbin/ldconfig -v
現在sysbench可以執行了！
[root@qht134 /]# /usr/local/sysbench/bin/sysbench --version
sysbench 1.1.0
