(翻墙VPS)谷歌云一年免费帐户申请+架设ShadowSocksR服务器+客户端设置

https://www.youtube.com/watch?v=z_GPMoymipA

利用谷歌云提供的300美元一年的免费试用, 可以架设个SSR的翻墙服务器用很久, 看YOUTUBE高清无压力.

相关下载请到 https://www.dengnz.com/youtube/

用到的命令:

//先跟着这个页面的1,2,3,4步添加docker repository

https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-using-the-repository

//安装docker

sudo apt-get update && sudo apt-get install docker-ce

//单命令架设SSR

sudo docker run -d --rm --name ssr -p 81:81 malaohu/ssr-with-net-speeder -s 0.0.0.0 -p 81 -k P@ssw0rd -m rc4-md5 -o http_simple

不是所有的参数都能在这个教程里用, 比如chacha20的加密算法就用不了, 因为这个docker image 的作者没有加libsodium 的包. 我有空会定制一个新的docker image, 把这些加进去.

对原理有兴趣的请看这里:

https://github.com/shadowsocksrr/shadowsocks-rss/blob/master/ssr.md

这里分享一个ShadowSocksR 服务器

ShadowSocks R

server: 35.229.147.33

port: 81

protocol: origin

password: 看视频最后几分钟

method: rc4-md5

Git - Reapply changes that were accidentally rollback

Here is the scenario

I made some changes and commit the file

I accidentally undo the change in my editor then made some more changes and commit

Now I realized the first change has been rollback.

Here is what I did

Find the finger print of my first change a6dfb30, and find the original finger print 7c54b25, use the following command to generate the patch file

git diff 7c54b25 a6dfb30 -- src/app/dashboard/dashboard.component.html > 1.patch

Then apply the patch

git apply 1.patch

Done

Docker nginx doesn't work with angular route

If you are serving angular app with nginx docker image, you will notice that your cannot directly access your app route Url directly from browser's address bar. You will get 404 file not found error.

To resolve this, you need to edit the default.conf file to tell nginx how to find files.

// Copy your conf.d directory out to your current dir

docker cp columnConcator:/etc/nginx/conf.d .

// Stop the container

docker stop columnConcator

// Edit the default.conf file in conf.d dir

// Update your location block as following:

location / {

root /usr/share/nginx/html;

index index.html index.htm;

try_files $uri $uri/ /index.html;

}

// copy modified directory back

sudo docker cp conf.d/ columnConcator:/etc/nginx

// restart the docker

docker start columnConcator

Done!

Use Kdiff3 for git diff

Firstly, put kdiff3 into the path

set path=%path%;C:\Program Files\KDiff3

Then run

git difftool --tool=kdiff3

You can calso config kdiff3 as the default diff tool

git config --global diff.tool kdiff3

Then you can just run

git difftool

use -y if you don't have to see prompts

git difftool -y

In Kdiff3's Config, you may would like to enable "Quit also via Esacpe key" to be able to quick exit kdiff3 for next file.

TextArea in Draggable container doesn't work well with firefox 60.0

I used the following module in my angular project.

https://www.npmjs.com/package/ng2-dnd

It works fine on google chrome.

Whereas on Firefox, the textarea inside a draggble container cannot get focus from mouse click. And it always scroll to top when typing.

MYBB enable HTTPS

I built a forum and enabled HTTPS for it though nginx_proxy and it's companion.

But certificate was not working.

I stop and rm the companion docker container and recreate it again.

sudo docker run \

--name companion \

-v /home/fennng/certs:/etc/nginx/certs:rw \

-v /var/run/docker.sock:/var/run/docker.sock:ro \

--volumes-from nginx-proxy \

jrcs/letsencrypt-nginx-proxy-companion

Problem resolved.

But with HTTPS, I got following error:

To fix this

remove http: from Board URL

Problem solved

Mixed content issue will come back if someone post images or medias with HTTP. I will leave it for now.

Compile gcc 2.95.3 with docker gcc

I tried to compile GCC 2.95.3 in docker.

Although I have solved so many issues, but still failed.

For getting GCC 2.95.3 in a docker container, here is the shortcut:

//Pull this docker image

docker pull lpenz/debian-etch-i386

//Create an docker container with this image and bash into it, run following command to install

docker run -v $PWD:/root -p 8202:8202 -it lpenz/debian-etch-i386 bash

apt-get update && apt-get install gcc-2.95

You will get gcc-2.95.4

If you are interested in building your own gcc 2.95.3 in docker ubuntu, the attach full story can be useful for you. I believe that I am quite close now. I have spent 3 days on this. It's enough for me.

=======================

Some useful commands

apt-get update && apt-get install gcc-4.9 flex gcc-multilib g++-multilib gperf autoconf make

rm /usr/bin/gcc

rm /usr/bin/cc

ln -s /usr/bin/gcc-5 /usr/bin/gcc

ln -s /usr/bin/gcc-5 /usr/bin/cc

linux32 bash

time ../gcc-2.95.3/configure --prefix=/opt/gcc-2.95.3 --enable-shared --enable-languages=c,c++ --enable-threads=posix

rm -rf texinfo

cp ../Makefile gcc/Makefile

time make bootstrap CC="gcc -std=gnu89"

export LIBRARY_PATH=/usr/lib/i386-linux-gnu

time make bootstrap CC="gcc -I /data/gcc-2.95.3 -std=gnu89"

make bootstrap CC="gcc -I /data/gcc-2.95.3 -std=gnu89 -B/usr/lib/i386-linux-gnu/"

make bootstrap CC="gcc -I /data/gcc-2.95.3 -std=gnu89 -I../glibc-2.10.1"

export C_INCLUDE_PATH=/data/gcc-2.95.3/glibc-workaround/include

export INCLUDE_PATH=/data/gcc-2.95.3/glibc-workaround/include

This is the step which I failed.

/data/gcc-build/gcc/xgcc -B/data/gcc-build/gcc/ -B/opt/gcc-2.95.3/i686-pc-linux-gnu/bin/ -c -g -O2 -I. -I../../../gcc-2.95.3/libio -I/data/gcc-2.95.3/include -D_IO_MTSAFE_IO -fpic ../../../gcc-2.95.3/libio/iogetline.c -o pic/iogetline.o

You can do above steps using any linux system.

../gcc-2.95.3/configure: 7: /tmp/cONf193.pos: cc: not found

*** The command 'cc -o conftest -g conftest.c' failed.

To build a gcc, you need to have a gcc first.... chicken first

A prebuild gcc needs to be installed.

So you need to has a linux with gcc

docker run -it -v %cd%:/data gcc:4 bash

better, but got this error:

Configuration x86_64-unknown-linux-gnu not supported

Configure in /data/gcc-build/gcc failed, exiting.

root@a77b0f2253d5:/data/gcc-build#

root@a77b0f2253d5:/data/gcc-build# cp /usr/share/libtool/config/config.{guess,sub} ../gcc-2.95.3

same error, doesn't help

Then used this command

../gcc-2.95.3/configure --prefix=/opt/i386/gcc/gcc-2.95.3 --enable-languages=c,c++ --enable-threads=posix --enable-shared --host i386-pc-linux-gnu

Or great, worked!!!

Then I do:

root@cfb1e30f20ef:/data/gcc-build# make bootstrap

Got error:

checking lex output file root... configure: error: cannot find output from lex; giving up

Makefile:1188: recipe for target 'config.status' failed

make[1]: *** [config.status] Error 1

make[1]: Leaving directory '/data/gcc-build/gcc'

Makefile:1493: recipe for target 'bootstrap' failed

make: *** [bootstrap] Error 2

It seems that I need to install flex

Not very confident with alpine, I then used another ubuntu docker and rollback config.sub and config.guess file. Same issue, I had to add x86_64* as well.

Then still got the same flex not found error. But his time it happen with the config command, not the make command.

Then I installed flex:

root@fb7cba64b1ba:/data/gcc-build# apt-get install flex

I got this error again:

Configuration x86_64-unknown-linux-gnu not supported

Configure in /data/gcc-build/gcc failed, exiting.

(this problem is solved using newer config.sub and config.guess file, I rolled back the file)

I had resolved above error with gcc:4, then this error happen again in ubuntu.

So, I may just need to install flex in gcc:4

I couldn't find apk in this container... strange

root@cfb1e30f20ef:/data/gcc-build# cat /proc/version

Linux version 4.9.87-linuxkit-aufs (root@95fa5ec30613) (gcc version 6.4.0 (Alpine 6.4.0) ) #1 SMP Wed Mar 14 15:12:16 UTC 2018

It looked like a alpine.

But ...

Debian GNU/Linux 8

It's actually a Debian

That's better, I can use apt-get update && apt-get install flex to install flex

run make bootstrap again

Got error:

Bootstrapping the compiler

make[1]: Entering directory '/data/gcc-build/gcc'

make[1]: *** No rule to make target 'bootstrap'. Stop.

make[1]: Leaving directory '/data/gcc-build/gcc'

Makefile:1490: recipe for target 'bootstrap' failed

I tried to run:

../gcc-2.95.3/configure --prefix=/opt/i386/gcc/gcc-2.95.3 --enable-languages=c,c++ --enable-threads=posix --enable-shared --host i386-pc-linux-gnu

again, but it stopped working.

with this error again:

Configuration x86_64-unknown-linux-gnu not supported

Configure in /data/gcc-build/gcc failed, exiting.

I reset the source code

Run

cp /usr/share/libtool/config/config.{guess,sub} ../gcc-2.95.3

../gcc-2.95.3/configure --prefix=/opt/gcc-2.95.3 --enable-shared --enable-languages=c,c++ --enable-threads=posix

../gcc-2.95.3/configure --prefix=/opt/i386/gcc/gcc-2.95.3 --enable-languages=c,c++ --enable-threads=posix --enable-shared --host i386-pc-linux-gnu

Then succeed again

Links are now set up to build a native compiler for i386-pc-linux-gnu

updating cache ../config.cache

creating ./config.status

creating Makefile

creating intl/Makefile

creating po/Makefile.in

creating fixinc/Makefile

creating cp/Makefile

creating auto-host.h

linking ../../gcc-2.95.3/gcc/intl/libgettext.h to intl/libintl.h

creating libintl.h

Configuring etc...

loading cache ../config.cache

checking for a BSD compatible install... (cached) /usr/bin/install -c

creating ./config.status

creating Makefile

Then much better!!!

Next time, I will install flex in the very beginning. It may need to be installed before config .

make bootstrap

Now we have different error:

Still no luck.

Then I tried to use linux32 to enter 32bit emu

linux32 bash

../gcc-2.95.3/configure --prefix=/opt/gcc-2.95.3 --enable-shared --enable-languages=c,c++ --enable-threads=posix

Great, works with the original config command.

The linux32 command will cheat bash to run in 32bit mode.

But still same error when run make bootstrap

I reset the source code again and start again, see what happen with linx32

../gcc-2.95.3/configure --prefix=/opt/gcc-2.95.3 --enable-shared --enable-languages=c,c++ --enable-threads=posix

Works, don't need to copy the new config.sub and config.guess files.

From the last command, it looks like it's a 32bit system. Then all the outputs of other commands are not reliable.

I tried the above command in a x64 system, got this.

Config.guess failed to determine the host type. You need to specify one.

This linux doesn't have sub and guess file, I copied the one from gcc:4

Configuring for a x86_64-unknown-linux-gnu host.

Created "Makefile" in /data/gcc-build using "mt-frag"

From another linux, we can see cc is just soft link of gcc

So, I create a alias for it

Someone proved that cpp-2.95.3 can be built from Ubuntu 14.1

To fix the error message from the question above: I commented out all the sections of the Makefiles of gcc-2.95.3 that compiled or installed texinfo or cpp.info.

https://unix.stackexchange.com/questions/204882/how-can-i-build-older-version-of-gcc/204937

I remove info and texinfo things from both Makefile and Makefile.in, ./gcc/Makefile

rerun config, and remove generated texinfo folder

cp -R glibc-workaround/include/bits libio/
