升级openssl

网站：https://www.openssl.org/source/openssl-1.1.1g.tar.gz

1.查看openssl版本

[root@iflytek ~]# openssl version
OpenSSL 1.0.1e-fips 11 Feb 2013

2.下载最新的openssl

[root@iflytek ~]# wget https://www.openssl.org/source/openssl-1.1.1g.tar.gz

3.解压并安装

[root@iflytek ~]# tar -zxvf openssl-1.1.1g.tar.gz
[root@iflytek ~]# cd openssl-1.1.1g/
[root@iflytek openssl-1.1.1g]# ./config --prefix=/usr/local/openssl  #如果此步骤报错,需要安装perl以及gcc包

[root@iflytek openssl-1.1.1g]# make && make install

4.备份原来openssl

[root@iflytek openssl-1.1.1g]# mv /usr/bin/openssl /usr/bin/openssl.bak_oldversion

5.设置软连接并声明

[root@iflytek openssl-1.1.1g]# ln -sf /usr/local/openssl/bin/openssl /usr/bin/openssl
[root@iflytek openssl-1.1.1g]# echo "/usr/local/openssl/lib" >> /etc/ld.so.conf #openssl的库文件
[root@iflytek openssl-1.1.1g]# ldconfig -v  #设置生效

6.查看版本

[root@iflytek openssl-1.1.1g]# openssl version
OpenSSL 1.1.1g  21 Apr 2020
