更新工具包
注:此更新步骤仅为建议,非必须
1 2 sudo yum -y updatesudo yum -y install vim bash-completion wget tar
更新后重启系统
安装工具包 1 2 3 4 5 sudo yum install epel-release yum-utilssudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpmsudo yum makecache fastsudo yum-config-manager --disable remi-php54sudo yum-config-manager --enable remi-php72
安装 php 和 Nginx
注:若二者已安装,此步可跳过
1 2 3 sudo yum -y install php-cli php-fpm php-mysql php-zip php-ldap sudo yum -y install php-devel php-gd php-mcrypt php-mbstring sudo yum -y install php-curl php-xml php-pear php-bcmath
安装好了后,检查一下 php 版本
若正常,会显示如下信息:
1 2 3 PHP 7.2.10 (cli) (built: Sep 11 2018 11:22:20) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
注:此处略去安装 Nginx 过程,如有需要,请参考其他教程
安装 Dokuwiki 下载前,先到 Github 检查一下它的最新稳定版本,此处假设为”2018-04-22b”
1 2 export RELEASE="2018-04-22b" wget https://github.com/splitbrain/dokuwiki/archive/release_stable_${RELEASE} .tar.gz
解压下载的安装包,并转移到新建的文件夹 /var/www/html/ 中
1 2 3 tar xvf release_stable_${RELEASE} .tar.gzsudo mkdir -p /var/www/html/ sudo mv dokuwiki-release_stable_${RELEASE} /var/www/html/dokuwiki
将文件夹 /var/www/html/dokuwiki 所有者权限修改为 nginx_user:nginx_group
注1:更改文件夹的所有者权限,方便 Nginx 有权访问该文件夹中的内容;此处假设 Nginx 进程运行在 nginx_user:nginx_group 下面,如果不是,则相应修改 注2:查看 nginx 所属用户 username 的办法为 ps aux | grep nginx
注3:查看某个用户 username 所属组的方法为 groups username
1 sudo chown -R nginx_user:nginx_group /var/www/html/dokuwiki
安装 SSL 证书 目的:支持使用 https 访问
安装 certbot-auto 到本地的 /usr/local/bin 下 目的:方便从 Letsencrypt 机构申请免费证书并简化后续的证书到期更新工作
注:若已安装过 certbot-auto 此步骤可略过
1 2 sudo wget https://dl.eff.org/certbot-auto -P /usr/local/binsudo chmod a+x /usr/local/bin/certbot-auto
配置 pip 国内源 注:若之前已配置,请跳过此步骤;此步骤的目的是加速 CertBot 下载 python 模块的速度
1 2 3 4 5 6 7 8 9 10 mkdir .pip && cd .pip vi pip.conf [global] index-url=http://mirrors.aliyun.com/pypi/simple/ [install] trusted-host=mirrors.aliyun.com
运行脚本,安装依赖 1 /usr/local/bin/certbot-auto --help
配置 nginx 目的:获取域名证书过程中, Let’s Encrypt 会对域名发起访问,以确认申请者对域名的所有权;故需要配置 nginx,以便能够对 Let’s Encrypt 的访问返回正确的响应;
1 2 3 4 mkdir /home/letsencrypt vi /usr/local/nginx/conf/nginx.conf
1 2 3 4 5 6 7 8 9 10 11 12 13 14 http { server { listen 80 ; server_name domain.example .com ; location ~ /.well-known/ acme-challenge/ { defaulf_type "text/plain" ; root /home/letsencrypt/; } }
重启 nginx 1 2 3 4 5 6 7 /usr/local/nginx/sbin/nginx -t > nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok /usr/local/nginx/sbin/nginx -s reload
运行脚本,申请证书 1 2 /usr/local/bin/certbot-auto certonly --email youremail.com --webroot -w /home/letsencrypt -d domain.example.com
申请成功后,界面下会有如下的成功提示:
1 2 3 4 5 IMPORTANT NOTES: - Congratulations! Your certificate and chain have been saved at /etc/letsencrypt/live/helloworld.com/fullchain.pem. Your cert will expire on 2019-08-26. To obtain a new version of the certificate in the future, simply run Let's Encrypt again......
注:记下以上提示信息中的 fullchain.pem 和 privkey.pem 两个文件路径,后续配置 nginx 会用到
配置 Nginx 打开 nginx 配置文件
1 2 vi /usr/local/nginx/conf/nginx.conf
在nginx 配置文件中,新增两个 server 条目,内容如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 server { listen 443 ssl; server_name domain.example.com; root /var/www/html/dokuwiki; access_log /var/log/dokuwiki.access.log; error_log /var/log/dokuwiki.error.log; ssl on; ssl_certificate /etc/letsencrypt/live/domain.example.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/domain.example.com/privkey.pem; ssl_session_timeout 5m; ssl_ciphers 'AES128+EECDH:AES128+EDH:!aNULL' ; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; index index.html index.php doku.php; location / { try_files $uri $uri / @dokuwiki; } location @dokuwiki { rewrite ^/_media/(.*) /lib/exe/fetch.php?media=$1 last; rewrite ^/_detail/(.*) /lib/exe/detail.php?media=$1 last; rewrite ^/_export/([^/]+)/(.*) /doku.php?do =export_$1 &id =$2 last; rewrite ^/(.*) /doku.php?id =$1 last; } location ~ /(data|conf|bin|inc)/ { deny all; } location ~* \.(css|js|gif|jpe?g|png)$ { expires 1M; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate" ; } location ~ \.php$ { fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_index index.php; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name ; fastcgi_intercept_errors off; fastcgi_buffer_size 16k; fastcgi_buffers 4 16k; } location ~ /\.ht { deny all; } } server { listen 80; server_name domain.example.com; location ~ /.well-known/acme-challenge/ { defaulf_type "text/plain" ; root /home/letsencrypt/; } location / { add_header Strict-Transport-Security max-age=2592000; rewrite ^ https://$host$request_uri ? permanent; } }
配置 php-fpm 打开以下 php-fpm 中的文件
1 sudo vim /etc/php-fpm.d/www.conf
将文件中以下几个键的值设置为如下:
1 2 3 4 5 6 7 user = nginx_user group = nginx_group listen = /var/run/php-fpm/php-fpm.sock listen.owner = nginx_user listen.group = nginx_group listen.mode = 0660
启动 nginx 和 php-fpm
1 2 sudo systemctl start php-fpmsudo systemctl enable php-fpm
重启 Nginx
1 2 3 4 5 6 /usr/local/nginx/sbin/nginx -t > nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok /usr/local/nginx/sbin/nginx -s reload
配置 DokuWiki 使用浏览器打开网址:https://domain.example.com/install.php,打开后页面如下,配置方法请参考其他教程
注:domain.example.com 请相应替换为实际域名
其他 Letsenctrypt 的证书有效期为三个月,当剩余一个月时,Letsenctrypt 会发通知邮件到预留的邮箱;收到通知后,只需要登录服务器,运行相关命令,即可自动更新证书
1 2 /usr/local/bin/certbot-auto renew --dry-run
若显示如下字样,则表示自动更新功能测试成功
1 2 3 4 Congratulations, all renewals succeeded. The following certs have been renewed: /etc/letsencrypt/live/www.helloworld.com/fullchain.pem (success) ** DRY RUN: simulating 'certbot renew' close to cert expiry ** (The test certificates above have not been saved.)
运行以下实际的更新命令,更新完了后,记得重启 nginx 服务器,以便启用新的证书
1 /usr/ local/bin/ certbot-auto renew -v
