nginx下证书配置

nginx 下 配 置 CA 认 证
 
为nginx配置https并自签名证书   开启443端口
 
实验环境: centos6.5    192.168.16.14
 
[root@localhost nginx]# rpm -qa | grep openssl
openssl-devel-1.0.1e-15.el6.x86_64
openssl-1.0.1e-15.el6.x86_64
 
一.准备证书
1.制作CA证书
ca.key CA私钥:
步骤与使用OpenSSL自签发服务器https证书所述大同小异。在这里再重复一次。
[root@localhost zhengshu]# pwd
/root/zhengshu
[root@localhost zhengshu]# openssl genrsa -des3 -out ca.key 2048    //制作ca.key 私钥
Generating RSA private key, 2048 bit long modulus
...............................+++
............................................................................................................+++
e is 65537 (0x10001)
Enter pass phrase for ca.key:         //输入ca.key私钥  tfo0zQ1JiP3PeZQVAzMy
Verifying - Enter pass phrase for ca.key:    //再次输入ca.key私钥    tfo0zQ1JiP3PeZQVAzMy
 
制作解密后的CA私钥(一般无此必要):
[root@localhost zhengshu]# openssl rsa -in ca.key -out ca_decrypted.key
Enter pass phrase for ca.key:         //输入ca.key私钥    tfo0zQ1JiP3PeZQVAzMy
writing RSA key
[root@localhost zhengshu]# ls
ca_decrypted.key  ca.key           //解密后的ca私钥和ca私钥
 
 
ca.crt CA根证书(公钥):
[root@localhost zhengshu]# openssl req -new -x509 -days 7305 -key ca.key -out ca.crt
Enter pass phrase for ca.key:         //输入ca.key私钥    tfo0zQ1JiP3PeZQVAzMy  
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.
-----
Country Name (2 letter code) [XX]:             //输入一个国家的名字,两字母代码  可为空
State or Province Name (full name) []:        //州或省名称 ,全名   可为空
Locality Name (eg, city) [Default City]:        //地区名称,如城市  可为空
Organization Name (eg, company) [Default Company Ltd]:           //组织名称,默认有限公司 可为空
Organizational Unit Name (eg, section) []:       //组织单元名称 ,可为空            
Common Name (eg, your name or your server's hostname) []:www.amber.com      //常见的名字(例如你的名字或你的服务器的主机名),输入该网址的域名,必填
Email Address []:       //邮件地址,可为空
[root@localhost zhengshu]# ls
ca.crt  ca_decrypted.key  ca.key           //ca公钥
 
 
2、制作生成网站的证书并用CA签名认证,在这里,假设网站域名为www.amber.com
生成www.amber.comt证书私钥:
[root@localhost zhengshu]# openssl genrsa -des3 -out www.amber.com.pem 1024
Generating RSA private key, 1024 bit long modulus
..............................++++++
......++++++
e is 65537 (0x10001)
Enter pass phrase for www.amber.com.pem:    //输入www.amber.com.pem口令   8BZNTubqWA3Y6A1aVJyW
Verifying - Enter pass phrase for www.amber.com.pem:     //再次输入www.amber.com.pem  口令    8BZNTubqWA3Y6A1aVJyW
 
 
制作解密后的www.amber.oom证书私钥:
[root@localhost zhengshu]# openssl rsa -in www.amber.com.pem -out www.amber.com.key
Enter pass phrase for www.amber.com.pem:  //输入www.amber.com.pem口令   8BZNTubqWA3Y6A1aVJyW
writing RSA key
[root@localhost zhengshu]# ls     //解密后的wwwamber.com.key证书私钥
ca.crt  ca_decrypted.key  ca.key www.amber.com.key  www.amber.com.pem
 
 
生成签名请求:
[root@localhost zhengshu]# openssl req -new -key www.amber.com.pem -out www.amber.com.csr
Enter pass phrase for www.amber.com.pem:     //输入www.amber.com.pem 口令   8BZNTubqWA3Y6A1aVJyW
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.
-----
Country Name (2 letter code) [XX]:     //输入一个国家的名字,两字母代码  可为空
State or Province Name (full name) []:       //州或省名称 ,全名   可为空
Locality Name (eg, city) [Default City]:      //地区名称,如城市  可为空
Organization Name (eg, company) [Default Company Ltd]:         //组织名称,默认有限公司 可为空
Organizational Unit Name (eg, section) []:        //组织单元名称 ,可为空  
Common Name (eg, your name or your server's hostname) []:www.amber.com    //常见的名字(例如你的名字或你的服务器的主机名),输入该网址的域名,必填
Email Address []:  //邮件地址,可为空
 
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:tutRLJVpkCXlfBJqtZDh   //输入密码
An optional company name []:ZX    //输入一个公司的名称
 
注:在common name中填入网站域名,如blog.creke.net即可生成改站点的证书,同时也可以使用泛域名如*.creke.net来生成所有二级域名可用的网站证书
 
 
 
用CA进行签名:
[root@localhost zhengshu]# openssl ca -policy policy_anything -days 1460 -cert ca.crt -keyfile ca.key -in www.amber.com.csr -out www.amber.com.crt
Using configuration from /etc/pki/tls/openssl.cnf
Enter pass phrase for ca.key:       //输入ca私钥   tfo0zQ1JiP3PeZQVAzMy
/etc/pki/CA/index.txt: No such file or directory
unable to open '/etc/pki/CA/index.txt'    //报错,不能打开这个目录..
140576737036104:error:02001002:system library:fopen:No such file or directory:bss_file.c:398:fopen('/etc/pki/CA/index.txt','r')
140576737036104:error:20074002:BIO routines:FILE_CTRL:system lib:bss_file.c:400:
 
注;其中,policy参数允许签名的CA和网站证书可以有不同的国家、地名等信息,days参数则是签名时限
 
报错解决方法:
如果在执行签名命令时,出现“I am unable to access the ../../CA/newcerts directory”
修改/etc/pki/tls/openssl.cnf中“dir = ./CA”
[root@localhost zhengshu]# vim /etc/pki/tls/openssl.cnf
42 dir             = ./CA 
 
然后:
mkdir -p CA/newcerts
touch CA/index.txt
touch CA/serial
echo "01" > CA/serial
 
[root@localhost zhengshu]# mkdir -p CA/newcerts
[root@localhost zhengshu]# touch CA/index.txt
[root@localhost zhengshu]# touch CA/serial
[root@localhost zhengshu]# echo "01" > CA/serial
再重新执行签名命令。
[root@localhost zhengshu]# openssl ca -policy policy_anything -days 1460 -cert ca.crt -keyfile ca.key -in www.amber.com.csr -out www.amber.com.crt
Using configuration from /etc/pki/tls/openssl.cnf
Enter pass phrase for ca.key:    //输入ca私钥   tfo0zQ1JiP3PeZQVAzMy   
Check that the request matches the signature
Signature ok

Certificate is to be certified until Sep  1 23:37:46 2020 GMT (1460 days)
Sign the certificate? [y/n]:y
 
 
1 out of 1 certificate requests certified, commit? [y/n]y
Write out database with 1 new entries
Data Base Updated
 
 
最后,把ca.crt的内容粘贴到www.amber.com.crt后面。这个比较重要!因为不这样做,可能会有某些浏览器不支持
[root@localhost zhengshu]# cat ca.crt >> www.amber.com.crt
 
好了,现在https需要到的网站私钥www.amber.com.key和网站证书www.amber.com.crt都准备完毕。接下来开始配置服务端。
 
 
二.配置nginx服务端
源码包安装nginx服务器
卸载rpm包安装的apache服务  ,可省略次步骤
[root@localhost zhengshu]# rpm -q httpd
package httpd is not installed
[root@localhost zhengshu]# rpm -e httpd --nodeps
[root@localhost zhengshu]# netstat -anpt | grep 80
 
安装nginx支持软件:
[root@localhost ~]# yum -y install pcre-devel zlib-devel gcc gcc-c++ make
[root@localhost ~]# rpm -q  pcre-devel zlib-devel gcc gcc-c++ make
pcre-devel-7.8-6.el6.x86_64
zlib-devel-1.2.3-29.el6.x86_64
gcc-4.4.7-4.el6.x86_64
gcc-c++-4.4.7-4.el6.x86_64
make-3.81-20.el6.x86_64
[root@localhost ~]# yum -y install pcre-devel zlib-devel
[root@localhost ~]# rpm -q  pcre-devel zlib-devel
pcre-devel-7.8-6.el6.x86_64
zlib-devel-1.2.3-29.el6.x86_64
 
创建运行用户,组:
[root@localhost ~]# useradd -M -s /sbin/nologin nginx
 
编译安装nginx:
[root@localhost soft]# pwd
/root/soft
[root@localhost soft]# ls
nginx-1.6.0.tar.gz
[root@localhost soft]# tar xf nginx-1.6.0.tar.gz -C /usr/src
[root@localhost soft]# cd /usr/src/nginx-1.6.0/
[root@localhost nginx-1.6.0]# ls
auto  CHANGES  CHANGES.ru  conf  configure  contrib  html  LICENSE  man  README  src
[root@localhost nginx-1.6.0]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module && make && make install    ///安装ssl模块
 
 
为程序nginx创建连接文件:
[root@localhost nginx-1.6.0]# ls /usr/local/nginx/
conf  html  logs  sbin
[root@localhost nginx-1.6.0]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
[root@localhost nginx-1.6.0]# ll /usr/local/sbin/
总用量 0
lrwxrwxrwx 1 root root 27 9月   3 08:04 nginx -> /usr/local/nginx/sbin/nginx
[root@localhost nginx-1.6.0]# nginx -t          //检测nginx语法
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@localhost nginx-1.6.0]# nginx   //启动nginx 服务
[root@localhost nginx-1.6.0]# netstat -anpt | grep nginx
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      5797/nginx  
 
 
在server{}段中设置:
[root@localhost conf]# cp nginx.conf nginx.conf.bak
[root@localhost conf]# vim nginx.conf
35     server {
36         listen       192.168.16.14:443;
37         ssl on;
38         ssl_certificate /usr/local/nginx/conf/www.amber.com.crt;       //密钥存放的路径
39         ssl_certificate_key /usr/local/nginx/conf/www.amber.com.key;     //密钥存放的路径
40         server_name  www.amber.com;     //网站域名
41        
 
 
[root@localhost ~]# cp zhengshu/* /usr/local/nginx/conf/        //把密钥都拷到/usr/local/nginx/conf/ 目录下
cp: 略过目录"zhengshu/CA"
 
nginx其他配置修改:
[root@localhost conf]# vim nginx.conf
 
  1
  2 user  nginx nginx;     //nginx程序账户及程序组
  3 worker_processes  2;   //指定要开启的进程,每个进程要消耗10M-20M内存,cpu要是多核,建议指定与cpu一样多的核数
