nginx检查报错 error while loading shared libraries: libprofiler.so.0: cannot open shared object file: No such file or directory

在centos7.3上编译安装nginx-1.12.2 启动测试出错

[root@web02 local]# /usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx: error while loading shared libraries: libprofiler.so.0: cannot open shared object file: No such file or directory

从错误看出是缺少lib文件导致，进一步查看下

可以看出libprofiler.so.0并没有找到

找出源文件

[root@web02 local]# find / -type f -name "libprofiler.so*"
/usr/local/lib/libprofiler.so.0.4.17
/usr/local/src/gperftools-2.6.90/.libs/libprofiler.so.0.4.17　

做软连接

[root@web02 local]# ln -sv /usr/local/lib/libprofiler.so.0.4.17 /lib64/libprofiler.so.0
‘/lib64/libprofiler.so.0’ -> ‘/usr/local/lib/libprofiler.so.0.4.17’　　

再次检查

[root@web02 local]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx-1.12.2/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx-1.12.2/conf/nginx.conf test is successful

ok了。
