centos6.5下安裝nginx配置https

要給項目裝https，記錄一下避免本身忘記。https在tomcat上也能夠作，但缺點就是隻給一個tomcat用，非專業的軟件作了專業的事情，感受仍是nginx來配置更好些。
當咱們用客戶端訪問https網站時，這個客戶端會生成對稱密鑰對咱們輸入的數據進行加密。服務端會將nginx配置的公鑰和私鑰中的公鑰下發給客戶端，客戶端用這個公鑰來把對稱密鑰進行加密，而後傳到服務端，服務端用私鑰來解密獲得對稱密鑰的密碼而後再解密成明文。爲何不直接用公鑰來加密呢，由於若是傳輸大的文件用算法加密會很是的慢。nginx的https的默認端口時443
下面下載：

wget http://zlib.net/zlib-1.2.11.tar.gz
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.39.tar.gz
wget https://www.openssl.org/source/openssl-1.0.1t.tar.gz

上面三個是依賴包，都是先configure而後make，make install安裝(沒裝編譯工具的話 須要安裝一下 yum -y install gcc gcc-c++)

wget http://nginx.org/download/nginx-1.9.0.tar.gz

安裝 ./configure --prefix=/usr/local/nginx --with-http_ssl_module報錯找不到庫文件

yum -y install openssl openssl-devel

安裝一下就能夠了而後再make，make install。
也是同上面同樣的安裝方式，啓動報錯找不着庫文件。去 /lib64 建立一下軟鏈接 ln -s /lib64/libpcre.so.0.0.1 /lib64/libpcre.so.1
而後建個目錄生成證書就能夠了。
先生成一個私鑰

openssl genrsa -des3 -out server.key 2048

再生成一個根證書

openssl req -new -key server.key -out server.csr

而後去除密碼

cp server.key server.key.org
openssl rsa -in server.key.org -out server.key

簽署簽名

openssl x509 -req -sha256 -days 365 -in server.csr -signkey server.key -out server.crt

而後對文件進行配置就沒問題了，必定要注意開啓防火牆端口，443。
