openssl版本升级并切换

安装 OpenSSL 1.0.x
# yum -y install openssl openssl-libs openssl-devel

安装 OpenSSL 1.1.x

# yum -y install epel-release
# yum -y install openssl11 openssl11-libs openssl11-devel


查看openssl版本：
# openssl version
OpenSSL 1.0.2k-fips  26 Jan 2017

# openssl11 version
OpenSSL 1.1.1k  FIPS 25 Mar 2021

# ll /usr/lib64/libssl*
# ll /usr/lib64/libcrypto*

ln -s <源文件路径> <链接路径>

-s: 必须参数，指定创建符号链接（软链接）
-f: 强制覆盖已存在的链接文件

ln -sf /usr/lib64/libssl.so.1.1 /usr/lib64/libssl.so
ln -sf /usr/lib64/libcrypto.so.1.1 /usr/lib64/libcrypto.so

或者

ln -sf /usr/lib64/libssl.so.1.1.1k /usr/lib64/libssl.so.1.1
ln -sf /usr/lib64/libcrypto.so.1.1.1k /usr/lib64/libcrypto.so.1.1

ln -s /usr/bin/openssl11 /usr/bin/openssl
ln -s /usr/include/openssl11/openssl /usr/include/openssl

注意：不能直接删除软链接
如需使用新版本，则需替换原来的软链接指向，即替换原动态库，进行版本升级
替换/lib(lib64)和/usr/lib(lib64)和/usr/local/lib(lib64)存在的相应动态库：

ln -sf /usr/lib64/libssl.so.1.1.1k /usr/lib64/libssl.so
ln -sf /usr/lib64/libcrypto.so.1.1.1k /usr/lib64/libcrypto.so

ln -sf /usr/lib64/libssl.so.1.1.1k /usr/lib64/libssl.so.10
ln -sf /usr/lib64/libcrypto.so.1.1.1k /usr/lib64/libcrypto.so.10

重新加载动态链接
ldconfig -v

检查下动态链接库是否有问题
cd /usr/bin/ && ldd openssl

编译的nginx有问题，应该在OpenSSL 1.1.1k下进行编译才行
