检出命令（git checkout）是git最常用的命令之一，同时也是个很危险的命令，因为这条命令会重写工作区：用法一：git checkout [-q] [<commit>] [–] <paths>… 用法二：git checkout [<branch>] 用法三：git checkout [-m] [[-b|–orphan] <new_branch>] [<start_point>] 上面列出的第一种用法和第二种用法的区别在于，第一种用法在命令中包含路径<paths>.为了避免路径和引用（或者提交id）同名而发生冲突，可以在<paths>前面用两个连续的短线（减号作为分割）第一种用法的<commit>是可选项，如果省略则相当于从暂存区进行检出（检出的默认值是暂存区）。第一种用法（包含了路径<paths>的用法）不会改变HEAD头指针，主要是用于指定版本的文件覆盖工作区中对应的文件。如果省略<commit>，则会用暂存区的文件覆盖工作区的文件，否则用指定提交中的文件覆盖暂存区和工作区中对应的文件. 第二种用法则会改变HEAD头指针，主要用作切换到分支，如果省略<branch>则相当于对工作区进行状态检查。第三种用法主要是创建和切换到新的分支(<new_branch>),新的分支从<start_point>指定的提交开始创建。新的分支和master分支没有什么实质的不同，都是在refs/heads命名空间下的引用。具体示例： git checkout branch 检出branch分支，要完成上图的三个步骤，更新HEAD以指向branch分支，以及用branch指向的树更新暂存区和工作区 git checkout 汇总显示工作区，暂存区与HEAD的差异 git checkout HEAD 同上 git checkout — filename 用暂存区中filename文件来覆盖工作区中的filename文件。相当于git add filename的撤消，这个命令很危险，因为对于本地的修改会悄无声息的覆盖 git checkout — . 或写作 git checkout .

python中的subprocess.Popen()使用

python中的subprocess.Popen()使用从python2.4版本开始,可以用subprocess这个模块来产生子进程,并连接到子进程的标准输入/输出/错误中去，还可以得到子进程的返回值。 subprocess意在替代其他几个老的模块或者函数，比如：os.system os.spawn* os.popen* popen2.* commands.* 一、subprocess.Popen subprocess模块定义了一个类： Popen class subprocess.Popen( args, bufsize=0, executable=None, stdin=None, stdout=None, stderr=None, preexec_fn=None, close_fds=False, shell=False, cwd=None, env=None, universal_newlines=False, startupinfo=None, creationflags=0) 各参数含义如下： args: args参数。可以是一个字符串，可以是一个包含程序参数的列表。要执行的程序一般就是这个列表的第一项，或者是字符串本身。 subprocess.Popen([“cat”,”test.txt”]) subprocess.Popen(“cat test.txt”) 这两个之中，后者将不会工作。因为如果是一个字符串的话，必须是程序的路径才可以。(考虑unix的api函数exec，接受的是字符串列表) 但是下面的可以工作 subprocess.Popen(“cat test.txt”, shell=True) 这是因为它相当于 subprocess.Popen([“/bin/sh”, “-c”, “cat test.txt”]) 在*nix下，当shell=False（默认）时，Popen使用os.execvp()来执行子程序。args一般要是一个【列表】。如果args是个字符串的话，会被当做是可执行文件的路径，这样就不能传入任何参数了。注意： shlex.split()可以被用于序列化复杂的命令参数，比如： >>> shlex.split(‘ls ps Read more…

CentOS 7 上使用Certbot申请通配符证书

在CentOS7上安装Certbot有三种方式：使用Certbot官方提供的对应平台的RPM包安装使用Certbot官方的提供的certbot-auto安装使用pip安装Certbot，因为Certbot是Python程序本文使用虚拟环境，使用pip安装Certbot 创建虚拟环境：可参考https://meaninglive.com/2020/06/15/%E5%88%9B%E5%BB%BA%E8%99%9A%E6%8B%9F%E7%8E%AF%E5%A2%83-ansible-python3-and-virtualenvs-on-centos-and-rhel/ 创建所需环境：

mkvirtualenv certbot 
workon certbot 
pip install -U setuptools pip pip install certbot-dns-route53 
参考：https://wsgzao.github.io/post/certbot/

mkvirtualenv certbot

workon certbot

pip install -U setuptools pip pip install certbot-dns-route53

参考：https://wsgzao.github.io/post/certbot/

用如下命令申请证书注意替换成自己的域名；执行该命令时不依赖nginx：

certbot -d meaninglive.com \
          -d *.meaninglive.com \
          --manual --preferred-challenges dns-01 \
          --server https://acme-v02.api.letsencrypt.org/directory \
          certonly --agree-tos

certbot -d meaninglive.com \

-d *.meaninglive.com \

--manual --preferred-challenges dns-01 \

--server https://acme-v02.api.letsencrypt.org/directory \

certonly --agree-tos

介绍下相关参数： certonly，表示安装模式，Certbot 有安装模式和验证模式两种类型的插件。 –manual 表示手动安装插件，Certbot 有很多插件，不同的插件都可以申请证书，用户可以根据需要自行选择 -d 为那些主机申请证书，如果是通配符，输入 *.devapi.haoshiqi.net（可以替换为你自己的域名） –preferred-challenges dns，使用 DNS 方式校验域名所有权 –server，Let’s Encrypt ACME v2 版本使用的服务器不同于 v1 版本，需要显示指定。输入应急邮箱，证书到期前会有邮件提示如果想跳过输入邮箱的步骤，可在申请命令后面加上：

--register-unsafely-without-email

1	--register-unsafely-without-email

之后出现如下提示：要公开记录申请该证书的IP地址，是否同意？不同意就无法继续。同意之后，出现如下提示，第一个“Press Enter to Continue”处直接回车，第二个“Press Enter to Continue”不要按回车：

自签名证书详解

总结下来，其实生成证书就两句话：

DOMAIN='www.example.com'

SUBJECT="/C=US/ST=Mars/L=iTranswarp/O=iTranswarp/OU=iTranswarp/CN=$DOMAIN"
openssl req -nodes -new -subj $SUBJECT -keyout $DOMAIN.key -out $DOMAIN.csr

printf "subjectAltName=DNS:localhost,IP:192.168.1.1" | \
openssl x509 -req -sha256 -days 3650 -in $DOMAIN.csr \
 -signkey $DOMAIN.key -out $DOMAIN.crt \
 -extfile /dev/stdin

DOMAIN='www.example.com'

SUBJECT="/C=US/ST=Mars/L=iTranswarp/O=iTranswarp/OU=iTranswarp/CN=$DOMAIN"

openssl req -nodes -new -subj $SUBJECT -keyout $DOMAIN.key -out $DOMAIN.csr

printf "subjectAltName=DNS:localhost,IP:192.168.1.1" | \

openssl x509 -req -sha256 -days 3650 -in $DOMAIN.csr \

-signkey $DOMAIN.key -out $DOMAIN.crt \

-extfile /dev/stdin

———————————————- 有一个shell脚本来自动生成证书：

—————证书知识补充——————————- 自签名证书 + Nginx 实现 HTTP 升级 HTTPS 很多内网平台在开发时候并没有考虑 HTTPS，想要从 HTTP 升级到 HTTPS 一般有两种方法：一种是更新所有相关前后端代码；另一种是基本不改变代码，用 Nginx 把 HTTPS 反向代理到 HTTP 接口。第一种方法工作量有点大，本文介绍下第二种方法，当然首先要做的是生成自签名证书。准备工作内网环境受影响的是软件安装升级和证书申请，所以需要制作本地 yum 和自签名证书，自签名证书稍后讲，制作本地 yum 库可参考链接内容， HTTPS 和 CA 基础知识查看这里。制作本地 yum 库，为了自动处理软件之间的依赖关系，一般都会用 yum 等软件包管理器来安装更新软件，默认 yum 是从互联网获取各种软件包的，内网环境就需要制作本地 yum Read more…

trust_host_root_certs: false

ngrok出现”bad certificate”的原因： 1. 看准了， server_address居然是直接使用的主域名， 2. 编译出来的ngrok程序一定是使用和server相同的证书产生的。如果server编译出来的在本地运行的时候出现“segment fault“，那么可以尝试着将/usr/local/ngrok放到本地，然后运行编译客户端的几行代码重新编译即可。 3. 客户端启动的配置文件中，trust_host_root_certs选项，除非你的证书是第三方的，否则就乖乖的使用false吧 ssl脚本执行目录：/root/ssl/ www目录: /root/www/challenges ， python -m SimpleHTTPServer 80 sendemail放置地方：/root/ssl/sendemail ＨＴＴＰ服务器准备如果胆儿大，直接执行如下的内容即可

How To Setup DNS Slave Auto Configuration Using Virtualmin/Webmin

实现步骤由于bind主从集群安装完成后，用webmin管理的话，在新创建主区域后，无法自动同步到从节点，现在找到解决办法了用Virtualmin去做主dns，去管理slave dns 在Post-Installation Wizard界面配置主从节点信息在server index里将从节点加入，用户名密码可以用webmin的主帐号 admin 在bind dns管理里在cluster slave servers里加入dns slave cluster改变的文件还是蛮多的：改变文件： /etc/webmin/virtual-server/config /etc/webmin/bind8/config /etc/webmin/servers/1592326172.serv /etc/named.rfc1912.zones /etc/named.conf 所以最好调cgi接口去做改动完了以后，就可以主从自动同步了其中修改完的virtual-server/config文件是这样的：

创建虚拟环境: Ansible, Python3, and Virtualenvs on CentOS and RHEL and MacOS

要为ansible运行创建一个最新的虚拟环境, 以下是步骤: 下载最新的python3.8.3安装包:

wget https://www.python.org/ftp/python/3.9.0/Python-3.9.0.tgz

1	wget https://www.python.org/ftp/python/3.9.0/Python-3.9.0.tgz

解压:

xz -d Python-3.9.0.tar.xz && tar xvf Python-3.9.0.tar

1	xz -d Python-3.9.0.tar.xz && tar xvf Python-3.9.0.tar

创建虚拟环境目录: mkdir /root/.python_env 编译安装python

cd Python-3.9.0/
./configure --prefix=/root/.python_env && make && make install

1 2	cd Python-3.9.0/ ./configure --prefix=/root/.python_env && make && make install

配置一下pip国内源, 以增加安装速度

cat > $HOME/.config/pip/pip.conf << EOF
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
trusted-host = mirrors.aliyun.com
#proxy=http://xxx.xxx.xxx.xxx:8080 # 替换出自己的代理地址，格式为[user:passwd@]proxy.server:port

[install]
trusted-host=mirrors.aliyun.com
EOF

cat > $HOME/.config/pip/pip.conf << EOF

[global]

index-url = http://mirrors.aliyun.com/pypi/simple/

trusted-host = mirrors.aliyun.com

#proxy=http://xxx.xxx.xxx.xxx:8080 # 替换出自己的代理地址，格式为[user:passwd@]proxy.server:port

[install]

trusted-host=mirrors.aliyun.com

EOF

安装virtualenvwrapper

cd .python_env/bin/
ln -s python3 python
ln -s pip3 pip
./pip install virtualenvwrapper

cd .python_env/bin/

ln -s python3 python

ln -s pip3 pip

./pip install virtualenvwrapper

安装过程中报错: ImportError: No module named ‘_ctypes’, 解决方法是(参考https://stackoverflow.com/questions/27022373/python3-importerror-no-module-named-ctypes-when-using-value-from-module-mul):

sudo yum -y install gcc gcc-c++ 
sudo yum -y install zlib zlib-devel
sudo yum -y install libffi-devel

sudo yum -y install gcc gcc-c++

sudo yum -y install zlib zlib-devel

sudo yum -y install libffi-devel

然后重新编译安装python3 定义环境变量

cat >> /root/.bashrc << EOF
# virtualenv
#export PIP_REQUIRE_VIRTUALENV=true #pip安装东西的时候不安装到本地环境
#export PIP_RESPECT_VIRTUALENV=true #在执行pip的时候让系统自动开启虚拟环境
# virtualenv
export WORKON_HOME=/root/.python_env/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/root/.python_env/bin/python
export PIP_VIRTUALENV_BASE=$WORKON_HOME
export VIRTUALENV_USE_DISTRIBUTE=1
export PATH="$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/root/.python_env/bin"
export VIRTUALENVWRAPPER_VIRTUALENV=/root/.python_env/bin/virtualenv
#export VIRTUALENVWRAPPER_VIRTUALENV=$(which virtualenv)
source $(which virtualenvwrapper.sh)
EOF

cat >> /root/.bashrc << EOF

# virtualenv

#export PIP_REQUIRE_VIRTUALENV=true #pip安装东西的时候不安装到本地环境

#export PIP_RESPECT_VIRTUALENV=true #在执行pip的时候让系统自动开启虚拟环境

# virtualenv

export WORKON_HOME=/root/.python_env/.virtualenvs

export VIRTUALENVWRAPPER_PYTHON=/root/.python_env/bin/python

export PIP_VIRTUALENV_BASE=$WORKON_HOME

export VIRTUALENV_USE_DISTRIBUTE=1

export PATH="$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/root/.python_env/bin"

export VIRTUALENVWRAPPER_VIRTUALENV=/root/.python_env/bin/virtualenv

#export VIRTUALENVWRAPPER_VIRTUALENV=$(which virtualenv)

source $(which virtualenvwrapper.sh)

EOF

创建ansible虚拟环境：

mkvirtualenv ansible

1	mkvirtualenv ansible

The prompt change tells us we’ve successfully made, and activated, our first python 3 virtualenv. Validate it is configured as Read more…
