centos7中使用docker建立wordpress博客,以及部分踩坑记录
首先前提准备 1.安装docker,这个到菜鸟教程里面就可以搜索到安装教程 2.安装python3环境,因为centos中预装了python2,所以需要下载重新配置下 3.docker安装wordpress的.yml文件 文章目录 问题1:docker-compose无法安装,docker-compose version命令不存在 问题2:安装docker-compose过程中报错 -----------------------更新分割线--------------------------------- 1.安装docker 2.centos7环境下安装python3环境 2.1 安装 2.1.1 、安装依赖环境 2.1.2 安装pip,用pip装wget 2.1.3 wget下载安装包 2.1.4 编译安装 2.1.5 建立python3的软链接 2.2 部分坑记录 2.2.1 3.docker安装wordpress的.yml文件 3.1 docker-compose安装 3.2 最后 docker-compose.yml文件 更新 补充: 问题1:docker-compose无法安装,docker-compose version命令不存在 cd /usr/local/bin/ wget https://github.com/docker/compose/releases/download/1.14.0-rc2/docker-compose-Linux-x86_64 rename docker-compose-Linux-x86_64 docker-compose docker-compose-Linux-x86_64 chmod +x /usr/local/bin/docker-compose 参考:https://blog.csdn.net/countofdane/article/details/95206131 问题2:安装docker-compose过程中报错 报错内容 ERROR: Command errored out with exit status 1: command: /usr/bin/python2 -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-zItSn5/pycparser/setup.py'"'"'; __file__='"'"'/tmp/pip-install-zItSn5/pycparser/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' egg_info --egg-base pip-egg-info cwd: /tmp/pip-install-zItSn5/pycparser/ Complete output (17 lines): Traceback (most recent call last): File "<string>", line 1, in <module> File "/tmp/pip-install-zItSn5/pycparser/setup.py", line 65, in <module> cmdclass={'install': install, 'sdist': sdist}, File "/usr/lib64/python2.7/distutils/core.py", line 112, in setup _setup_distribution = dist = klass(attrs) File "/usr/lib/python2.7/site-packages/setuptools/dist.py", line 269, in __init__ _Distribution.__init__(self,attrs) File "/usr/lib64/python2.7/distutils/dist.py", line 287, in __init__ self.finalize_options() File "/usr/lib/python2.7/site-packages/setuptools/dist.py", line 302, in finalize_options ep.load()(self, ep.name, value) File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2341, in load return self.resolve() File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2351, in resolve raise ImportError(str(exc)) ImportError: 'module' object has no attribute 'check_specifier' ---------------------------------------- ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output. 解决方法: sudo pip install --upgrade pip sudo pip install --upgrade setuptools 参考: https://www.cnblogs.com/liubiaos/p/9444485.html https://blog.csdn.net/liuyunshengsir/article/details/79136379 -----------------------更新分割线--------------------------------- 1.安装docker 在菜鸟教程官网有下载教程,搜索即可https://www.runoob.com/docker/docker-compose.html 或者看我写的一个教程 https://blog.csdn.net/weixin_42245375/article/details/103447571 2.centos7环境下安装python3环境 部分小命令整理: 1.Linux系统下如何查看当前所处目录位置 #pwd 2.centos7更新pip版本 pip install --upgrade pip 2.1 安装 2.1.1 、安装依赖环境 yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel 2.1.2 安装pip,用pip装wget yum -y install epel-release yum install python-pip#安装pip pip install wget #安装wget 2.1.3 wget下载安装包 sudo mkdir /usr/local/python3 # 创建安装目录 wget --no-check-certificate https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz #下载文件 tar -xzvf Python-3.7.0.tgz # 解压 cd Python-3.7.0 #进入 2.1.4 编译安装 sudo ./configure --prefix=/usr/local/python3 # 指定创建的目录 sudo make && sudo make install 2.1.5 建立python3的软链接 sudo ln -s /usr/local/python3/bin/python3 /usr/bin/python3 **备注:**关于建立软链接这部分,我是这个写法,其他博主也有说直接软链接到默认的python的,那样为防止对yum有影响,需要修改yum配置文件,如下 sudo ln -s /usr/local/python3/bin/python3 /usr/bin/python 修改 yum 配置文件 sudo vi /usr/bin/yum 将第一行指定的 python 版本改为 python2.7(#!/usr/bin/python 改为 #!/usr/bin/python2.7) vi /usr/libexec/urlgrabber-ext-down 2.2 部分坑记录 2.2.1 解决也很简单,但是一开始没想到,我们单独装这个 more-itertools 库,装 5.0.0 版本就好。 pip install more-itertools==5.0.0 再次执行安装最新版本 pip install sentry 3.docker安装wordpress的.yml文件 3.1 docker-compose安装 pip install docker-compose 3.2 最后 docker-compose.yml文件 文件内容: version: '3.3' services: db: image: mysql:5.7 volumes: - db_data:/var/lib/mysql restart: always environment: MYSQL_ROOT_PASSWORD: somewordpress MYSQL_DATABASE: wordpress MYSQL_USER: wordpress MYSQL_PASSWORD: wordpress wordpress: depends_on: - db image: wordpress:latest ports: - "8000:80" restart: always environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_USER: wordpress WORDPRESS_DB_PASSWORD: wordpress WORDPRESS_DB_NAME: wordpress volumes: db_data: {} 进入该文件所在目录,一行命令运行 docker-compose up -d 最后通过浏览器访问url: ip:8000 即可访问博客主页 完成。。
