實驗須知:node
實驗主機1:192.168.1.11,做爲web服務器web
實驗主機2:192.168.1.12,做爲CA簽署證書的主機apache
配置流程:vim
(1) 爲服務器申請數字證書;這裏出於測試的目的,須要創建私有CAwindows
建立私有CA瀏覽器
在web服務器上建立證書籤署請求bash
CA證書籤署服務器
(2) 配置httpd支持使用ssl及使用的證書併發
(3) 測試基於https訪問的主機ide
配置步驟:
在12主機:
[root@node2 ~]# cd /etc/pki/CA [root@node2 CA]# (umask 077;openssl genrsa -out private/cakey.pem2048)Generating RSA private key, 2048 bit long modulus ..............................................................................+++ ..................................................................+++ e is 65537 (0x10001) [root@node2 CA]# openssl req -new -x509 -key private/cakey.pem -outcacert.pem -days 10000 CN BJ BJ Magedu Ops ca.mageu.com [root@node2 CA]# touch index.txt [root@node2 CA]# echo 01 > serial
在11主機:
#cd/etc/httpd/ #mkdir ssl #cd ssl # (umask077;openssl genrsa -out http.key 1024) #openssl req-new -key http.key -out http.csr CN BJ BJ MageEdu Ops www.a.com #scp http.csr@172.16.11.12:/tmp
在12主機:
[root@node2 tmp]# cd /tmp/ [root@node2 tmp]# opensslca -in http.csr -out http.crt -days 3655 [root@node2 tmp]#scp http.crt172.16.100.11:/etc/httpd/ssl/
在11主機:
#yum install mod_ssl-y #rpm -ql mod_ssl #vim /etc/httpd/conf.d/ssl.conf ……….. <VirtualHost192.168.1.11:443> DocumentRoot "/vhosts/a.com/htdocs" ServerName www.a.com:443 ……… SSLCertificateFile/etc/httpd/ssl/http.crt SSLCertificateKeyFile/etc/httpd/ssl/http.key ……….. #httpd–t #servicehttpd restart #ss–tnl …..查看是否有443端口……..
在12主機:
#cd /etc/pki/CA #scp cacert.pem 172.16.1.11:/tmp
此時能夠在瀏覽器中輸入:https://192.168.1.11測試;
最後一步,將/tmp目錄下的證書cacert.pem文件導入windows桌面,並更更名爲cacert.crt,雙擊安裝證書便可;如今咱們須要在瀏覽器中輸入:https://www.a.com能正常顯示網頁信息,就在windows裏面改hosts文件:
……..添加…………..
192.168.1.11 www.a.com
再次輸入https://ww.a.com,觀察顯示結果
壓力測試工具ab的使用:
用法:
#ab [options] URL
-c:請求的最大併發數
-n:總的請求數
-k:以持久鏈接的模式測試
使用示例:
