假如我們在centos7上安裝nginx時，會附帶的安裝一個openssl-devel的包，但是我們安裝的時候會出現以下報錯：可能是因為openssl-devel的版本太低。

Error: Package: 1:openssl-devel-1.0.1e-60.el7.x86_64 (base)
           Requires: openssl-libs(x86-64) = 1:1.0.1e-60.el7
           Installed: 1:openssl-libs-1.0.2k-21.el7_9.x86_64 (@updates)
               openssl-libs(x86-64) = 1:1.0.2k-21.el7_9
           Available: 1:openssl-libs-1.0.1e-60.el7.x86_64 (base)
               openssl-libs(x86-64) = 1:1.0.1e-60.el7
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
 

1.如果虛擬機器聯網，直接安裝

[root@proxy-master ~]# wget ftp://ftp.pbone.net/mirror/ftp.centos.org/7.9.2009/updates/x86_64/Packages/openssl-devel-1.0.2k-21.el7_9.x86_64.rpm

http://rpm.pbone.net/resultsb_dist_94_size_1581144_name_openssl-devel-1.0.2k-21.el7_9.x86_64.rpm.html

然後安裝

[root@rs1 ~]# rpm -ivh openssl-devel-1.0.2k-21.el7_9.x86_64.rpm
 

如果提示以下報錯

[root@rs1 ~]# rpm -ivh openssl-devel-1.0.2k-21.el7_9.x86_64.rpm 
error: Failed dependencies:
    krb5-devel(x86-64) is needed by openssl-devel-1:1.0.2k-21.el7_9.x86_64
    zlib-devel(x86-64) is needed by openssl-devel-1:1.0.2k-21.el7_9.x86_64

說明沒有下面的兩個包， 直接安裝下面的兩個包，

[root@rs1 ~]# yum -y install krb5-devel zlib-devel
 

然後更新一樣openssl-devel包

[root@rs1 ~]# rpm -ivh openssl-devel-1.0.2k-21.el7_9.x86_64.rpm --force
