确认系统中是否已安装openssl工具,没有就安装

yum install openssl openssl-devel -y

确认/etc/pki/CA目录下是否有以下文件，没有则自行创建

mkdir -pv /etc/pki/CA/{certs,crl,newcerts,private}

touch /etc/pki/CA/{serial,index.txt}

指定证书编号

cd /etc/pki/CA
echo 01 >> serial

生成CA私钥

umask 077; openssl genrsa -out /etc/pki/CA/private/cakey.pem 4096

根据私钥生成CA证书

openssl req -new -x509 -key /etc/pki/CA/private/cakey.pem -out /etc/pki/CA/cacert.pem -days 3650

 

生成服务端证书

生成服务端私钥

创建要给存放服务端证书文件的目录

mkdir ./https  && cd ./https
openssl genrsa -out https.pem 4096

生成服务端证书请求

# 查看证书信息
openssl x509  -in /etc/pki/CA/cacert.pem -noout -subject
# 生成证书请求
openssl req -new -key https.pem -out https.csr -days 365 -subj "/C=cn/ST=beijingshi/L=beijingshi/O=Default Company Ltd/OU=navysummer/CN=navysummer.top/emailAddress=navysummer@yeah.net"

生成服务端证书

openssl ca -in https.csr -out https.crt -days 365

 Nginx上添加配置

ssl_certificate https.crt;
ssl_certificate_key  https.key;
