openssl 패키지 다운로드 및 체크섬 확인

• OpenSSL : https://www.openssl.org/source/

curl -fsSL https://www.openssl.org/source/openssl-1.1.1n.tar.gz --output /usr/local/src/openssl-1.1.1n.tar.gz

curl -fsSL https://www.openssl.org/source/openssl-1.1.1n.tar.gz.sha256 --output /usr/local/src/openssl-1.1.1n.tar.gz.sha256

echo "$(cat openssl-1.1.1n.tar.gz.sha256) openssl-1.1.1n.tar.gz" | sha256sum --check

$ echo "$(cat openssl-1.1.1n.tar.gz.sha256) openssl-1.1.1n.tar.gz" | sha256sum --check
openssl-1.1.1n.tar.gz: OK

openssl 설치 및 설정

openssl 설치

tar xfz /usr/local/src/openssl-1.1.1n.tar.gz -C /usr/local/src/

./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlib

make && make install

echo "/usr/local/ssl/lib" > /etc/ld.so.conf.d/openssl-1.1.1n.conf

ldconfig -v

environment 편집

• /usr/local/ssl/bin 추가

vim /etc/environment

$ vim /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/ssl/bin"

source /etc/environment; echo $PATH | grep '/usr/local/ssl/bin'

$ echo $PATH | grep '/usr/local/ssl/bin'
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/ssl/bin
