Requirements for Running Symfony
Symfony 3.3 requires PHP 5.5.9 or higher to run, in addition to other minor
requirements. To make things simple, Symfony provides a tool to quickly check if
your system meets all those requirements.
Beware that PHP can define a different configuration for the command console and
the web server, so you need to check requirements in both environments.
Checking Requirements for the Web Server
Symfony includes a config.php file in the web/ directory of your project.
Open that file with your browser to check the requirements.
Once you've fixed all the reported issues, delete the web/config.php file
to avoid leaking internal information about your application to visitors.
Checking Requirements for the Command Console
Open your console or terminal, enter in your project directory, execute this
command and fix the reported issues:
2$ cd my-project/
$ php bin/symfony_requirements

Follow SymfonyCentOS6.4&安装oracle&11g&遇到的各种问题
最近在CentOS6.4安装
oracle，先安装的10g,各种的不通过，郁闷的要命，后面直接又安装11G.
cpio.gz文件的解压
从官网上下载的10201_database_linux_x86_64.cpio.gz,文件需要解压。
1、先解压.gz&& #gunzip&10201_database_linux_x86_64.cpio.gz
2、第一步解压之后 文件名称变成 10201_database_linux_x86_64.cpio
3、再解压.cpio&& #cpio&-idmv&10201_database_linux_x86_64.cpio
问题二 报错信息：libXp.so.6
/lib/i386/libawt.so:&libXp.so.6:&cannot&open&shared&object&file:&No&such&file&or&directory"
解决办法：建议直接把centos接入互联网，然后yum，从网上下载好多各种包，都没有这个来的快。比如上面的报错,直接#yum
install libXp.so.6，直接就可以进行网上匹配安装。
问题三、安装页面中文乱码
oracle 用户登录在执行./runInstaller之前设置语言
#export&LC_ALL=en_US.UTF-8
&&&&&&#LANG=en_US&./runInstaller
这样就可以看到安装文件是英文版了，就不再是口口口了。
问题四、swap安装不通过
This is a prerequisite condition to test whether sufficient total
swap space is available on the system.&(more
Expected Value
&:&15.64GB
Actual Value
问题原因是没有swap空间不足导致，需要扩大交换空间
&&解决：1、使用dd命令创建一个swap分区
&&&&&&&&&&2、#dd&if=/dev/zero&of=/home/swap&bs=1024&count=
3、格式化刚才创建的分区
4、# mkswap
/home/swap
5、再使用swapon命令把这个文件分区变成swap分区
6、#swapon /home/swap
7、（关闭SWAP分区的命令为：#swapoff
/home/swap)
8、再用free -m 查看已经扩容的了swap分区。
9、为了能够让swap自动挂载，需要修改etc/fstab文件，用vi /etc/fstab
10、在文件末尾加上 /home/swap swap swap default 0 0
11、这样就算重启系统，swap分区也不用手动挂载了
& 12、但是我感觉好像我重启了系统
swap就没有了，然后我又百度了一下，要执行下面一段命令&
#echo&& "swapon&
/home/swap" &&
/etc/inittab&
13、然后在看 vi 看下 /etc/inittab
&&&&&&&&&&14、最后一行是swapon&
/home/swap，这样就万事大吉了。
问题五、vi使用
问题六、安装rpm包的时候老是说键值堆错误，Header V3 DSA signature: NOKEY, key
&解决办法：rpm&-ivh&db4-devel-4.3.29-9.fc6.i386.rpm&--force&--nodeps
问题七、semopm&
验证不通过
This&is&a&prerequisite&condition&to&test&whether&the&OS&kernel&parameter&"semopm"&is&properly&set.&(more&details)
Expected&Value&:&100
Actual&Value&:&32
解决办法：
编辑/etc/sysctl.conf文件，添加
kernel.sem=250&32000&100&128
启用刚所做的变更。&输入命令：&#&/sbin/sysctl&-p
问题八、file-max 验证不通过
This&is&a&prerequisite&condition&to&test&whether&the&OS&kernel&parameter&"file-max"&is&properly&set.&(more&details)
Expected&Value
&:&6815744
Actual&Value
This&is&a&prerequisite&condition&to&test&whether&the&OS&kernel&parameter&"ip_local_port_range"&is&properly&set.&(more&details)
Expected&Value
&:&between&9000&&&65500
Actual&Value
&:&between&9000&&&65000
This&is&a&prerequisite&condition&to&test&whether&the&OS&kernel&parameter&"aio-max-nr"&is&properly&set.&(more&details)
Expected&Value
&:&1048576
Actual&Value
&解决办法：修改内核文件
启用刚所做的变更。&输入命令：&#&/sbin/sysctl&-p
fs.aio-max-nr&=&1048576
fs.file-max&=&6815744
kernel.shmall&=&2097152
kernel.shmmax&=&
kernel.shmmni&=&4096
kernel.sem&=&250&32000&100&128
net.ipv4.ip_local_port_range&=&9000&65500
net.core.rmem_default&=&262144
net.core.rmem_max&=&4194304
net.core.wmem_default&=&262144
net.core.wmem_max&=&1048576

This error means that Windows does not recognize the input file as something it is able to affix a digital signature on.
Possible workaround
Using SetReg.exe
to disable Certificate Revocation List checking.
setreg 3 FALSE
setreg 9 FALSE
Reference:
I can try the workaround above to sort the problem, but i was in belief that VS 2013 RC can be easily updated?
VS 2013 can be installed side by side with previous versions of Visual
Studio or, if you have a VS 2013 pre-release, it can be installed
straight over
top of the pre-release.
I've tried using web installer or downloading ISO image again, with no success, as possible solutions in related sources.

then choose Web Installer (the first download option)
If you have already tried installing VS 2013 using ISO Installer you must reboot before trying the Web Installer.

Try to verify whether you have completely downloaded installer, in case if you are using ISO file. I've checked my own with the same problem, and it was broken. Sha hash was different.

I had the same issue while installing RTM version. I replaced the files from the RC version I had downloaded earlier. This is what I did to fix the issue
Uninstall the failed version of 2013 from control panel -> Uninstall programs
Restart the computer
Extract the files from the ISO to a local folder
Replace the the folder "Packages/vsGragphics Helper..." with the copy from RC version ISO.
Re-run the setup again from local folder.
One thing that can cause this error is if the setup files have not been successfully extracted from the ISO.
In the case I've just dealt with, a number of setup files were 0 bytes in length.
The problem can be worked around by deleting the affected folder(s) in "packages" so that the installer will download the missing content.
Or fixed by identifying the cause of the corruption, e.g., you may need to use different software to extract the contents of the ISO, or the ISO itself may have been corrupted.
For me the issue resolved by getting the ISO again. Do check if your ISO is broken using its SHA.
This means the vsgraphics_helperbits.MSI is corrupt. I was able to resolve my issue by navigating to ( \packages\vsgraphics_helper\ ) and renaming (amd64) folder to (amd6488s) and for some reason adding 888s to the folder name makes the installer reach out to the internet to download the vsgraphics that are broken in the ISO.
