1. 生成keystore
    注册在填写名子与姓氏时需要填写tomcat的主机ip地址
    keytool -genkey -v -alias tomcat -keyalg RSA -keystore tomcat.keystore -validity 365
2. 准备生成 CA 的key
    openssl genrsa -out myCA.key 2048
3. 生成 CA
    openssl req -x509 -new -key myCA.key -out myCA.cer -days 730 -subj /CN="Sencloudx Custom CA"
4. 准备从 CA 请求认证的请求文件
    keytool -certreq -alias tomcat -keystore tomcat.keystore -file server.csr
5. 从CA请求认证

有时候在Finder右侧的远程共享内看不到局域网内已经共享的主机，可用如下方法连接

1. 知道ip地址可以直接用在Finder窗口中使用苹果+k连，
  输入windows的用户和密码即可（有的版本的windows默认关闭了共享帐号登录的）。

2. 也可以这样：smb://pc的ip或者机器名/
