天翼云重启Nginx：error while loading shared libraries: liblz4.so.1

今天早上 的时候，有位plus用户问  重启Nginx报这个错误，怎么解决呀，

1. error while loading shared libraries: liblz4.so.1: cannot open shared object file: No such file or directoryerror while loading shared libraries: liblz4.so.1: cannot open shared object file: No such file or directory<p></p><div></div>

我首先看到有个liblz4.so这个共享库不存在，大概是安装的时候选择的是急速安装的，导致这个库没有加载到或者没有安装上，给出的解决方案1 是使用编译方式安装下Nginx。不得不说，客户的机器真的很强，一会就编译好了，但是启动报错，这错误很明显：哦豁，不就是端口被占用了嘛，引起这个的问题就是有服务器使用这些端口pkill -9 nginx
,先杀死服务，再重启  /etc/init.d/nginx start 试试
到这里大家觉得已经解决了吧！要是已经解决了本帖就无意义了。。

后面到 rpm包官网找到了这个

查看客户的操作系统版本是CentOS7.3.这个包是CentOS7.9的，给客户沟通，升级下操作系统吧，

1. yum update -y

复制代码

期间更还被系统加固拦截，又让用户关闭了下系统加固，天翼云，网速可以的，YES！ 等了5分钟不到，666666，升级成功，重新编译Nginx  可以了
