tar -zxvf openssl-1.0.2p.tar.gz 

3、切換至解壓目錄中，我這裏是解壓到/opt目錄中

# cd /opt
# ll
drwxr-xr-x 20 root root    4096 Aug 17 23:57 openssl-1.0.2p
# cd openssl-1.0.2p
#

4、進行編譯安裝

# ./config 
#
# make && make install  *註：需要提前安裝好gcc開發編譯環境*

5、由於編譯安裝的默認安裝位置為/usr/local/ssl下，需要通過設置軟連接來訪問

# ln -s /usr/local/ssl/bin/openssl  /usr/bin/opessl
# ln -s /usr/local/ssl/include/openssl /usr/include/
# echo "/usr/local/ssl/lib" >> /etc/ld.so.conf
# ldconfig -v

6、查看是否升級成功

# openssl version -a
OpenSSL 1.0.2p  14 Aug 2018

Centos Openssl升級
