近期升级了一下openssl的版本
1. 安装依赖
yum group install 'Development Tools'
yum install perl-core zlib-devel -y
2. 下载openssl并解压
wget https://www.openssl.org/source/openssl-1.1.1c.tar.gz
tar -xf openssl-1.1.1c.tar.gz
3. 安装
cd openssl-1.1.1c
./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlib
make
make test
make install
4. 配置
cd /etc/ld.so.conf.d/
创建openssl-1.1.1c.conf文件，写入
/usr/local/ssl/lib
reload the dynamic link
ldconfig -v
5. Configure OpenSSL Binary
mv /bin/openssl /bin/openssl.backup
创建/etc/profile.d/openssl.sh文件，写入
#Set OPENSSL_PATH
OPENSSL_PATH="/usr/local/ssl/bin"
export OPENSSL_PATH
PATH=$PATH:$OPENSSL_PATH
export PATH
设置为可执行
chmod +x /etc/profile.d/openssl.sh
source /etc/profile.d/openssl.sh
6. 检查版本
openssl version -a
