测试环境

AnolisOS-8.6-x86_64-minimal.iso
Virtual Box，2 vCPU, 4G RAM, 40 vDisk

安装依赖

yum install -y make gcc

编译安装GmSSL

unzip GmSSL-master.zip
**注：**由于许多系统有自带的 ssl 库，为避免潜在的动态库冲突，此处仅生成静态库
./config –prefix=/usr/local/gmssl –openssldir=/usr/local/gmssl no-shared
make && make install
加到系统环境变量
echo ‘export PATH=“$PATH:/usr/local/gmssl/bin”’ >> ~/.bash_profile
source ~/.bash_profile
查看版本
gmssl version
gmssl ciphers -v |grep SM

OpenVPN编译安装

安装依赖

yum install -y gcc libnl3-devel libcap-ng-devel openssl-devel lz4-devel lzo-devel pam-devel make

tar -zxvf openvpn-2.5.10.tar.gz

cd openvpn-2.5.10

./configure OPENSSL_LIBS=“-L/usr/local/gmssl/lib /usr/local/gmssl/lib/libssl.a /usr/local/gmssl/lib/libcrypto.a -lpthread -ldl”
OPENSSL_CFLAGS=-I/usr/local/gmssl/include –includedir=/usr/local/gmssl/include
–libdir=/usr/local/gmssl/lib –prefix=/usr/local/openvpn

重点1： 两个静态库要指定。
重点2： -lpthread -ldl 要指定。
变量名不能写错， OPENSSL_CFLAGS、 OPENSSL_LIBS
