Linux下ssl+http 实现 HTTPS 访问服务器设置

yum install httpd php
1.配置CA服务器
vim /etc/pki/tls/openssl.cnf
修改第45行，更改存放证书目录
dir = ../../CA
dir = /etc/CA
修改第178行，让服务器支持自签名
#basicConstraints=CA:FALSE
自签名的证书可以使用
basicConstraints=CA:TRUE
cd /etc/pki/CA
配置生成CA证书脚本 42行
vim /etc/pki/tls/misc/CA
CATOP=../../CA
CATOP=/etc/CA

运行脚本生成CA证书
/etc/pki/tls/misc/CA -newca
CA certificate filename (or enter to create) 回车

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

将证书请求发送给CA

CA服务器对证书请求进行数字签名
openssl ca -keyfile /etc/CA/private/cakey.pem -cert /etc/CA/cacert.pem -in /tmp/server.csr -out /tmp/server.crt
/etc/CA/private/cakey.pem ca私钥
/tmp/server.csr 证书请求
/etc/CA/cacert.pem ca证书
/tmp/server.crt 数字证书名字
/etc/httpd/conf.d web私钥

报错：
failed to update database
TXT_DB error number 2
解决：
cd /etc/CA 修改yes为no
vim index.txt.attr
unique_subject = yes
unique_subject = no

将签名后的数字证书颁发给web服务器
cp /tmp/server.crt /etc/httpd/conf.d/

配置web支持ssl实现https
yum install mod_ssl
vim /etc/httpd/conf.d/ssl.conf
修改112行 数字证书签名
SSLCertificateFile /etc/pki/tls/certs/localhost.crt

SSLCertificateFile /etc/httpd/conf.d/server.crt
修改119行 web私钥
SSLCertificateKeyFile /etc/pki/tls/private/localhost.key

SSLCertificateKeyFile /etc/httpd/conf.d/server.key

启动 httpd 服务
service httpd restart
输入密码
验证安全可信度
把/etc/CA/private/cakey.pem 文件复制到ftp
下在后把此文件导入到浏览器
火狐 编辑 配置 高级 查看证书 导入 找到ca证书 选三个勾 ok
