nginx安装
1.首先下载nginx的网络源
[root@localhost ~]# rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2.使用yum安装nginx
[root@localhost ~]# yum install nginx

Resolving Dependencies
--> Running transaction check

Error: Package: 1:nginx-1.16.0-1.el7.ngx.x86_64 (nginx)
Requires: libcrypto.so.10(OPENSSL_1.0.2)(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
3.此时我们看到如下报错，说缺少libcrypto.so.10这个包
Error: Package: 1:nginx-1.16.0-1.el7.ngx.x86_64 (nginx)
Requires: libcrypto.so.10(OPENSSL_1.0.2)(64bit)
4.但经过查询，其实是有这个包的
[root@localhost ~]# find / -name libcrypto.so.10
find: ‘/run/user/1000/gvfs’: Permission denied
/usr/lib64/libcrypto.so.10 ##是有这个东西
[root@localhost ~]# openssl version ##查看openssl版本
OpenSSL 1.0.2o 27 Mar 2018
[root@localhost ~]# rpm -q --provides openssl
openssl = 1:1.0.1e-60.el7
openssl(x86-64) = 1:1.0.1e-60.el7
5.查看当前库文件中的 libcrypto.so.10
[root@localhost ~]# rpm -q --provides openssl-libs | grep libcrypto.so.10
libcrypto.so.10()(64bit)
libcrypto.so.10(OPENSSL_1.0.1)(64bit)
libcrypto.so.10(OPENSSL_1.0.1_EC)(64bit)##libcrypto.so.10(OPENSSL_1.0.2)(64bit)
libcrypto.so.10(libcrypto.so.10)(64bit)
6.把升级OpenSSL 1.0.1到OpenSSL 1.0.2
在右下角找到并下载
| CentOS 7.7.1908 for x86_64 | openssl-libs-1.0.2k-19.el7.x86_64.rpm |
上传到服务器后，使用rpm进行升级，为了防止和已经有的版本冲突，强制安装(--force)
[root@ /home/kiosk/repod]# rpm -ivh openssl-libs-1.0.2k-16.el7.x86_64.rpm --force
warning: openssl-libs-1.0.2k-16.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY

现在用yum安装nginx，发现已经可以正常安装了
