舊版本openssl1.0.2k
新版本openssl1.1.1
安裝所需環境
yum install wget vim gcc gcc-c++ zlib zlib-devel
下載主程序
wget -c -P /opt/tmp/ https://www.openssl.org/source/openssl-1.1.1.tar.gz
解壓縮
cd /opt/tmp/
tar zxvf openssl-1.1.1.tar.gz
cd opensll-1.1.1
配置程序安裝目錄
./config shared zlib --prefix=/usr/local/openssl --openssldir=/usr/local/openssl/ssl
顯示配置數據
perl configdata.pm --dump
編譯安裝
make -j 4
make install
查看新安裝版本
cd /usr/local/openssl/bin
./openssl version -a
此處顯示錯誤，說明找到不libssl.so.1.1庫
./openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory
查看新版本openssl關聯的動態庫
ldd openssl
linux-vdso.so.1 => (0x00007fff12142000)
libssl.so.1.1 => not found
libcrypto.so.1.1 => not found
libz.so.1 => /lib64/libz.so.1 (0x00007f702c2e5000)

設置關聯動態庫配置文件
echo "/usr/local/openssl/lib" >> /etc/ld.so.conf.d/openssl-1.1.1.conf
使配置文件生效
ldconfig -v
查看當前openssl版本
openssl version -a
備份openssl當前版本並關聯新版本數據
mv /usr/bin/openssl /usr/bin/openssl.old
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
openssl version -a
