想到是13年买的A410，应该升级一下，可官网都没了，最后搜索到这个16年的最新固件：
https://drivers.softpedia.com/get/DVD-BluRay-Media-Players/Cloud-Media/Cloud-Media-Popcorn-Hour-A-410-Media-Player-Firmware-050816061625POP425802.shtml
通过USB顺利更新了一把。

再查看mac可以开nfs，方法如下：

sudo vi /etc/exports
加入：

/ -sec=sys

 

/Users /Users/popeye /Users/popeye/movies -ro -mapall=popeye:staff -alldirs

检查配置：

sudo nfsd checkexports


重启：

sudo nfsd restart

这里要注意movies目录是我重新建立的755权限，不要用系统原来的目录，不然总是访问不了。

再到A410里网络浏览里就能找到了。

在最后的编译选项里添上:
-flat_namespace -undefined suppress -lz

就可以编译出: livestatus.o

livecheck编不过,报找不到n_short:

vi ./check_icmp.c 
把这个调整到INCLUDE序列的最后即可:

June 30, 2011 | By 

This tutorial will walk you through how to configure SSL (https://localhost:8443 access) on Tomcat in 5 minutes.

apache tomcat Setting Up SSL on Tomcat in 5 minutes (https://localhost:8443)

For this tutorial you will need:

  • Java SDK (used version 6 for this tutorial)
  • Tomcat (used version 7 for this tutorial)

The set up consists in 3 basic steps:

  1. Create a keystore file using Java
  2. Configure Tomcat to use the keystore
  3. Test it
  4. (Bonus ) Configure your app to work with SSL (access through https://localhost:8443/yourApp)

1 – Creating a Keystore file using Java

Fisrt, open the terminal on your computer and type:

Windows:

cd %JAVA_HOME%/bin

Linux or Mac OS:

cd $JAVA_HOME/bin

The $JAVA_HOME on Mac is located on “/System/Library/Frameworks/JavaVM.framework/Versions/{your java version}/Home/”

You will change the current directory to the directory Java is installed on your computer. Inside the Java Home directory, cd to the bin folder. Inside the bin folder there is a file named keytool. This guy is responsible for generating the keystore file for us.

Next, type on the terminal:

keytool -genkey -alias tomcat -keyalg RSA

When you type the command above, it will ask you some questions. First, it will ask you to create a password (My password is “password“):

loiane:bin loiane$ keytool -genkey -alias tomcat -keyalg RSA Enter keystore password:  password Re-enter new password: password What is your first and last name?   [Unknown]:  Loiane Groner What is the name of your organizational unit?   [Unknown]:  home What is the name of your organization?   [Unknown]:  home What is the name of your City or Locality?   [Unknown]:  Sao Paulo What is the name of your State or Province?   [Unknown]:  SP What is the two-letter country code for this unit?   [Unknown]:  BR Is CN=Loiane Groner, OU=home, O=home, L=Sao Paulo, ST=SP, C=BR correct?   [no]:  yes  Enter key password for 	(RETURN if same as keystore password):  password Re-enter new password: password

It will create a .keystore file on your user home directory. On Windows, it will be on: C:\Documents and Settings\[username]; on Mac it will be on /Users/[username] and on Linux will be on /home/[username].

2 – Configuring Tomcat for using the keystore file – SSL config

Open your Tomcat installation directory and open the conf folder. Inside this folder, you will find the server.xml file. Open it.

Find the following declaration:

<!-- <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"     maxThreads="150" scheme="https" secure="true"     clientAuth="false" sslProtocol="TLS" /> -->

Uncomment it and modify it to look like the following:

Connector SSLEnabled="true" acceptCount="100" clientAuth="false"     disableUploadTimeout="true" enableLookups="false" maxThreads="25"     port="8443" keystoreFile="/Users/loiane/.keystore" keystorePass="password"     protocol="org.apache.coyote.http11.Http11NioProtocol" scheme="https"     secure="true" sslProtocol="TLS" />

Note we add the keystoreFile, keystorePass and changed the protocol declarations.

3 – Let’s test it!

Start tomcat service and try to access https://localhost:8443. You will see Tomcat’s local home page.

Note if you try to access the default 8080 port it will be working too: http://localhost:8080

4 – BONUS - Configuring your app to work with SSL (access through https://localhost:8443/yourApp)

To force your web application to work with SSL, you simply need to add the following code to your web.xml file (before web-app tag ends):

<security-constraint> 	<web-resource-collection> 		<web-resource-name>securedapp</web-resource-name> 		<url-pattern>/*</url-pattern> 	</web-resource-collection> 	<user-data-constraint> 		<transport-guarantee>CONFIDENTIAL</transport-guarantee> 	</user-data-constraint> </security-constraint>

The url pattern is set to /* so any page/resource from your application is secure (it can be only accessed with https). The transport-guarantee tag is set to CONFIDENTIAL to make sure your app will work on SSL.

If you want to turn off the SSL, you don’t need to delete the code above from web.xml, simply changeCONFIDENTIAL to NONE.

Reference: http://tomcat.apache.org/tomcat-7.0-doc/ssl-howto.html (this tutorial is a little confusing, that is why I decided to write another one my own).

Happy Coding!

http://www.mysql.com/downloads/

下来后先装:mysql-5.5.27-osx10.6-x86_64.pkg
它是装到/usr/local/mysql,到此目录运行下:
./scripts/mysql_install_db --user mysql

通过这个启动:
./bin/mysqld_safe

排错:
看下上面的LOG提示.
Can't find file: './mysql/host.frm' :一般是没权限,把DATA目录删除,再用上面命令建一次
unknow option:把/etc/my.cnf删除掉,里面有新版本不认识的上一版本遗留配置
说mysql.sock找不到,这个版本是在/tmp/目录下哦!

再把剩下两个包装了,就可以通过配置面板启动了:
MySQL.prefPane
MySQLStartupItem.pkg

下次升级可能要给下/usr/local/mysql/data目录的权限
