Vagrantfile安装CentOS虚拟机 一、virtualbox安装1、下载 https://www.virtualbox.org/2、在主板开启CPU虚拟化，自行百度3、安装，直接下一步，选择安装路径。二、安装虚拟机1、下载虚拟系统CentOS7https://app.vagrantup.com/boxes/search Vagrant官方镜像仓库https://www.vagrantup.com/ Vagrant下载2、初始化虚拟系统打开安装好的virtualbox软件，打开window cmd窗口，运行下面命令，即可初始化一个CentOS7系统。初始化之后window用户文件夹夹会多出一个Vagrantfile文件。此时virtualbox界面就会多出一个CentOS系统了。vagrant box add centos/7 CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box 或 Vagrant init centos/73、启动虚拟机，初始root用户密码vagrant，此时看到virtualbox中的CentOS正在启动。vagrant up4、vagrant其他命令使用vagrant用户链接至CentOS虚拟机，初始root用户密码vagrant。vagrant ssh上传文件vagrant upload source [destination][name][id]更多命令可以访问官网文档5、设置固定ip，默认虚拟机ip是随机的，方式1-修改Vagrantfile，方式2-进入linx系统修改网卡配置信息,下面为修改Vagrantfile改ip：config.vm.network "private_network",ip:"192.168.10.1"6、重启虚拟机vagrant reload7、启动，除了上面的3启动虚拟机，也可以在virtualbox界面选择虚拟机右键开启。8、virtualbox界面还可以设置虚拟机内存大小等信息，更多设置可以查看官网。9、开启ssh登录linux虚拟机。10、进入虚拟机目录cd /etc/sysconfig/network-scripts/配置网卡信息vi ifcfg-eth1修改网卡网关和dns：# The contents below are automatically generated by Vagrant. Do not modify. NM_CONTROLLED=yes BOOTPROTO=none ONBOOT=yes IPADDR=192.168.56.10 NETMASK=255.255.255.0 GATEWAY=192.168.56.1 DNS1=114.114.114.114 DNS2=8.8.8.8 DEVICE=eth1 PEERDNS=no #VAGRANT-END如上加了GATEWAY=192.168.56.1和DNS1=114.114.114.114 、DNS2=8.8.8.8。切换到root用户：su root提示输入root密码，默认密码vagrant。然后重启网卡服务：service network restart11、修改ssh登录，默认未开启。修改linx配置文件vi /etc/ssh/sshd_configPasswordAuthentication no将no改为yes重启ssh服务：service sshd restart现在就可以使用ssh工具进行远程连接了。

Docker搭建Typecho博客 博客一直使用firekylin搭建，最近看着typecho活跃度还可以，于是本周末用docker重新搭建了博客。一、环境说明操作系统：CentOS7.6技术：Docker、MySQL、PHP、Nginx使用工具：Xftp 7、Xshell 7、Notepad++博客系统：Typecho二、安装步骤Docker环境搭建Docker安装MySQLDocker安装PHPDocker安装Nginx三、遇到问题安装mysql、php、nginx时，映射文件路径错误，导致安装好后，找不到文件。Nginx配置时映射路径错误、80端口自动转发443端口，导致http访问一直追加路径。证书路径放置错误。Typecho初始化安装时，提示"对不起，无法连接数据库，请先检查数据库配置再继续进行安装"。四、解决方案通过docker log 容器，查看日志，一步步解决。添加异常提示代码：, $e->getMessage()instal.php第56行，添加ob_start();ip地址错误，默认localhost，docker安装时，需要改成公网ip或局域网ip。未创建typecho数据库。Nginx配置文件:server { listen 443 ssl http2 reuseport; server_name yanxizhu.com www.yanxizhu.com; root /var/www/html/yanxizhu.com; index index.php; ssl on; ssl_certificate /etc/nginx/conf.d/自己证书.crt; ssl_certificate_key /etc/nginx/conf.d/自己证书key.key; ssl_session_cache shared:SSL:1m; ssl_session_timeout 5m; ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; access_log /var/log/nginx/typecho_access.log main; if (!-e $request_filename) { rewrite ^(.*)$ /index.php$1 last; } location ~ .*\.php(\/.*)*$ { include fastcgi_params; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_index index.php; fastcgi_pass phpfpm:9000; fastcgi_split_path_info ^(.+\.php)(.*)$; } } server { listen 80; server_name yanxizhu.com www.yanxizhu.com; rewrite ^(.*) https://yanxizhu.com$1 permanent; }

Docker安装Nginx 一、Docker安装Nginx拉取Nginx镜像docker pull nginx:1.10随便启动一个nginx 实例，只是为了复制出配置docker run -p 80:80 --name nginx -d nginx:1.10拷贝容器内的配置文件docker container cp nginx:/etc/nginx .重命名文件夹mv nginx conf 移动配置文件到/mydata/nginx下mv conf /mydata/nginx/终止原容器docker stop nginx删除原容器docker rm nginx运行Nginx容器,参数见-说明1docker run -d -p 80:80 -p 443:443 --name nginx -v /mydata/nginx/html:/var/www/html -v /mydata/nginx/conf/conf.d:/etc/nginx/conf.d -v /mydata/nginx/logs:/var/log/nginx --link php:phpfpm --name nginx nginx:1.10设置随Docker启动docker update --restart=always nginx二、Nginx配置https协议SSL-443配置，在/mydata/nginx/conf/conf.d下新建配置文件yanxizhu.com.conf，内容如下：server { listen 443 ssl http2 reuseport; server_name yanxizhu.com www.yanxizhu.com; root /var/www/html/yanxizhu.com; index index.php; ssl on; ssl_certificate /etc/nginx/conf.d/自己证书.crt; ssl_certificate_key /etc/nginx/conf.d/自己证书key.key; ssl_session_cache shared:SSL:1m; ssl_session_timeout 5m; ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; access_log /var/log/nginx/typecho_access.log main; if (!-e $request_filename) { rewrite ^(.*)$ /index.php$1 last; } location ~ .*\.php(\/.*)*$ { include fastcgi_params; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_index index.php; fastcgi_pass phpfpm:9000; fastcgi_split_path_info ^(.+\.php)(.*)$; } } server { listen 80; server_name yanxizhu.com www.yanxizhu.com; rewrite ^(.*) https://yanxizhu.com$1 permanent; }注意：映射路径、文件存放路径、证书路径。https://www.yanxizhu.com/ 博客SSL配置如上，使用的mysql、php、nginx、typecho搭建。

Docker安装PHP Docker安装PHP拉取PHP镜像docker pull php:7.4-fpm运输PHP容器docker run -d -v /mydata/nginx/html:/var/www/html -p 9000:9000 --link mysql:mysql --name php php:7.4-fpm进入PHP容器docker exec -it php /bin/bashPHP扩展安装(非必须)docker-php-ext-install pdo_mysql设置随Docke启动docker update --restart=always php注意：自己映射路径/mydata/nginx/html。
