nginx扩展之支持多个ssl加密虚拟主机

nginx支持一台服务器唯一IP:PORT，根据server_name创建区分多个经过ssl加密的https虚拟主机，apache不支持

生成www.magedu.net域名证书：

[[email protected] logs]# cd /etc/pki/tls/certs/
[[email protected] certs]# vim Makefile
%.key:
        umask 77 ; \
        #/usr/bin/openssl genrsa -aes128 $(KEYLEN) > $@
        /usr/bin/openssl genrsa $(KEYLEN) > $@                    #去掉-aes128，创建私钥key时，不会再有输入密码加密key的过程，生成无加密的key
[[email protected] certs]# mv magedu.net* /apps/nginx4/ssl/
[[email protected] certs]# ll /apps/nginx4/ssl/                      #
total 16
-rw------- 1 root root 1330 Mar  8 15:23 magedu.net.crt
-rw-r--r-- 1 root root 1679 Mar  8 15:22 magedu.net.key
-rw------- 1 root root 1330 Mar  7 14:11 magedu.org.crt
-rw------- 1 root root 1675 Mar  7 14:12 magedu.org.key

nginx配置：

[[email protected] certs]# vim /apps/nginx4/conf/conf.d/test.conf
server {
        listen 443 ssl;
        listen 80;
        server_name www.magedu.org;
        root /data/site14/;
        #ssl on;
        ssl_certificate /apps/nginx4/ssl/magedu.org.crt;
        ssl_certificate_key /apps/nginx4/ssl/magedu.org.key;
        ssl_session_cache shared:sslcache:20m;
        ssl_session_timeout 10m;
        access_log /apps/nginx4/logs/magedu.org.ssl.access.log  access_json ;
        location / {
                if ($scheme = http) {
                        rewrite ^/(.*)$ https://www.magedu.org/$1 permanent;
                }
        }
}
server {
        listen 443 ssl;
        listen 80;
        server_name www.magedu.net;
        root /data/site1/;
        ssl_certificate /apps/nginx4/ssl/magedu.net.crt;
        ssl_certificate_key /apps/nginx4/ssl/magedu.net.key;
        ssl_session_cache shared:sslcache:20m;
        ssl_session_timeout 10m;
        access_log /apps/nginx4/logs/magedu.net.ssl.access.log  access_json;
        location / {
                if ($scheme = http) {
                        rewrite ^/(.*)$ https://www.magedu.net/$1 permanent;
                }
        }
}
