安装

  1. 官网下载安装包https://www.dokuwiki.org/
  2. 安装php和nginx yum install -y php70w php70w-gd php70w-xml php70w-fpm nginx
  3. 开机自启动 systemctl enable nginx php-fpm
  4. 配置nginx
    server {
        listen       80;
        server_name  localhost;
        # Maximum file upload size is 4MB - change accordingly if needed
        client_max_body_size 4M;
        client_body_buffer_size 128k;

        root /dokuwiki;
        index doku.php;

        #Remember to comment the below out when you're installing, and uncomment it when done.
        location ~ /(conf/|bin/|inc/|install.php) { deny all; }

        #Support for X-Accel-Redirect
        location ~ ^/data/ { internal ; }

        location ~ ^/lib.*\.(js|css|gif|png|ico|jpg|jpeg)$ {
             expires 365d;
        }

        location / { try_files $uri $uri/ @dokuwiki; }

        location @dokuwiki {
            # rewrites "doku.php/" out of the URLs if you set the userwrite setting to .htaccess in dokuwiki config page
            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=$1&$args last;
        }

        location ~ \.php$ {
            try_files $uri $uri/ /doku.php;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param REDIRECT_STATUS 200;
            fastcgi_pass 127.0.0.1:9000;
        }
    }
  1. 启动nginx和php-fpm systemctl start php-fpm nginx
  2. 在网站一栏输入:http://你的ip地址/install.php 在右上角选好语言,简体中文zh,按照提示安装即可。如果打开页面保存,请修改conf、data、lib目前的权限。

安装插件

  1. 新增页面Add New Page插件

  2. Markdown插件Markdown Page Plugin

  3. 侧边栏

    • 安装Indexmenu Plugin插件
    • 新建data\pages\sidebar.txt,内容如下:
        ===== 导航目录 =====
        {{indexmenu>..|navbar}}
        ===== 添加新页面 =====
        {{NEWPAGE}}
    

中文文件名乱码

修改dokuwiki/conf/local.php在最后一行加上:

$conf['fnencode']='utf-8';

此处是centos系统(系统默认字符编码utf-8)下修改乱码,windows系统请参考文章末尾的原文地址。

集成editor.md

  1. 下载editor.md
    https://github.com/pandao/editor.md/archive/v1.5.0.tar.gz
  2. 解压到dokuwiki\lib\editor.md\
  3. 替换/inc/form.php里的函数form_wikitext($attrs),修改return结果
    function form_wikitext($attrs) {
        // mandatory attributes
        unset($attrs['name']);
        unset($attrs['id']);
        $text = str_replace("<markdown>\n",'',$attrs['_text']);
        $text = str_replace("\n</markdown>",'',$text);
        return '<div id="editormd" contenteditable="true"><textarea name="wikitext">'.DOKU_LF.formText($text).'</textarea></div>';
    }

代码中id="editormd"是后面editor.md实例需要的id

  1. 在/inc/parser/xhtml.php里更改cdata函数
    function cdata($text) {
        //$this->doc .= $this->_xmlEntities($text);
        return $this->doc.=$text;
    }

替换原因是:因为以前是纯字符编辑器,会将一些特殊符号进行过滤,比如:<>等等.而替换之后的xheditor本身已经做了一次过滤了,再次过滤就会导致字符<变成&lt,因此去掉这段之后,就只过滤一次

  1. inc/Action/Save.php的
    saveWikiText($ID,con($PRE,$TEXT,$SUF,true),$SUM,$INPUT->bool('minor')); //use pretty mode for con
    替换成
    saveWikiText($ID,con($PRE,"<markdown>\n".$TEXT."\n</markdown>",$SUF,true),$SUM,$INPUT->bool('minor')); //use pretty mode for con
  1. lib/tpl/dokuwiki/main.php添加editor.md包
<link rel="stylesheet" href="<?php echo DOKU_BASE;?>lib/editor.md/css/editormd.min.css" />
    <script src="<?php echo DOKU_BASE;?>lib/editor.md/editormd.js"></script>
    <script type="text/javascript">
    $ = jQuery
        var testEditor;
        $(function(md) {
        if (document.getElementById("editormd")) {
            testEditor = editormd("editormd", {
                width: "100%",
                height: 740,
                path: '<?php echo DOKU_BASE;?>lib/editor.md/lib/',
                syncScrolling : "single",
                imageUpload: true,
                imageFormats: ["jpg", "jpeg", "gif", "png", "bmp", "webp"],
                imageUploadURL: "<?php echo DOKU_BASE;?>uploadimg.php",
                onload: function() {}
            });
        }
        });

        window.onload = function() {
            //document.getElementById("editormd").addEventListener('paste', function (event) {
            $("#editormd").on('paste', function(event) {
                //console.log(event);
                var items = (event.clipboardData || event.originalEvent.clipboardData).items;
                for (var index in items) {
                    var item = items[index];
                    //console.log(item);
                    if (item.kind === 'file') {
                        var blob = item.getAsFile();                        
                        var reader = new FileReader();
                        reader.onload = function(event) {                            
                            var base64 = event.target.result;
                            console.log(base64);
                            //ajax上传图片
                            $.post("<?php echo DOKU_BASE;?>uploadimg.php", {
                                screenshots: base64
                            }, function(rets) {
                                ret = JSON.parse(rets);
                                //layer.msg(ret.msg);
                                console.log(ret);
                                if (ret.success === 1) {
                                    //新一行的图片显示
                                    testEditor.insertValue("\n![](" + ret.url + ")");
                                } else {
                                    alert("截图上传失败:" + ret.message);
                                }
                            });
                        };
                        reader.readAsDataURL(blob);
                    }
                }
            });
        }
    </script>

  1. 图片上传支持
    将如下代码保存到uploadimg.php文件,放到dokuwiki根目录下
<?php
if(!defined('DOKU_INC')) define('DOKU_INC', dirname(__FILE__).'/');
require_once(DOKU_INC.'inc/init.php');

$INFO = pageinfo();
$hostpath=getBaseURL(false);
$attachDir='/data/media/editor/';//上传文件保存路径,结尾不要带/
$maxAttachSize = 2*1024*1024;  //最大上传大小,默认是2M

function upEditorImg(){
    global $hostpath, $attachDir, $maxAttachSize;
    //获取文件的大小
    $file_size=$_FILES['editormd-image-file']['size'];
    //echo "$file_size $maxAttachSize";
    if($file_size > $maxAttachSize) {
        echo '{"success":0,"message":"不能上传大于2M的文件"}';
        return false;
    }

    //获取文件类型
    $file_type=$_FILES['editormd-image-file']['type'];
    if($file_type!="image/jpeg" && $file_type!='image/pjpeg' && $file_type!="image/png") {
        echo '{"success":0,"message":"图片格式异常"}';
        return false;
    }

    //判断是否上传成功(是否使用post方式上传)
    if(is_uploaded_file($_FILES['editormd-image-file']['tmp_name'])) {
        //把文件转存到你希望的目录(不要使用copy函数)
        $uploaded_file=$_FILES['editormd-image-file']['tmp_name'];

        //我们给每个用户动态的创建一个文件夹
        $save_path=$_SERVER['DOCUMENT_ROOT'].$hostpath.$attachDir;
        //判断该用户文件夹是否已经有这个文件夹
        if(!file_exists($save_path)) {
            mkdir($save_path);
        }

        //$move_to_file=$save_path."/".$_FILES['editormd-image-file']['name'];
        $file_true_name=$_FILES['editormd-image-file']['name'];
        $move_file_name=time().rand(1,1000).substr($file_true_name,strrpos($file_true_name,"."));
        $move_to_file=$save_path.$move_file_name;
        //echo "$uploaded_file   $move_to_file";
        if(move_uploaded_file($uploaded_file,iconv("utf-8","gb2312",$move_to_file))) {
            //echo $_FILES['editormd-image-file']['name']."上传成功";
            //echo '{"success":1,"message":"上传成功", "url":"'.$hostpath.$attachDir.$move_file_name.'"}';
            $result=array(
              'success'=> 1,
              'message'=>'上传成功',
              'url'=>'editor:'.$move_file_name
            );
            echo json_encode($result);
        } else {
            //echo "上传失败";
            echo '{"success":0,"message":"服务器保存文件失败"}';
        }
    } else {
        //echo "上传失败";
        echo '{"success":0,"message":"上传失败"}';
        return false;
    }
}

//$_POST= [screenshots] => data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAI0AAACcCAYAAABC1CibAAAL6UlEQVR4Ae2dbUiU6RrH...
function upEditorScreenshots(){
    global $hostpath, $attachDir, $maxAttachSize;

    $content = $_POST['screenshots'];

    if (preg_match('/^data:image\/(\w+);base64,(\S+)/', $content, $result)) {
        $file_type = $result[1];
        $base64data = $result[2];

        //echo "$file_type $base64data";
        $save_path = $_SERVER['DOCUMENT_ROOT'].$hostpath.$attachDir;
        if (!is_dir($save_path)) {
            mkdir($save_path, 0777);
        }

        $filedata = base64_decode($base64data);
        $filename = time().rand(1,1000).".".$file_type;
        if (!file_put_contents($save_path . $filename, $filedata)) {
            echo '{"success":0,"message":"服务器保存文件失败"}';
            return false;
        }
        unset($filedata);

        echo '{"success":1,"message":"上传成功", "url":"editor:'.$move_file_name.$filename.'"}';
        return true;
    } else {
        echo '{"success":0,"message":"图片格式异常"}';
        return false;
    }
}

//print_r($_POST);
//print_r($_FILES);

if(isset($_FILES['editormd-image-file'])){
    global $INFO;
    if($INFO['writable'] && !$INFO['locked']) {
        upEditorImg();
    } else {
    echo '{"success":0,"message":"没有权限"}';
    }
    exit();
}

if(isset($_POST['screenshots'])){
    global $INFO;
    if($INFO['writable'] && !$INFO['locked']) {
        upEditorScreenshots();
    } else  {
    echo '{"success":0,"message":",没有权限"}';
    }
    exit();
}
?>

代码中添加了权限校验和兼容dokuwiki获取图片url

  1. 修改图片加载地址
    修改lib/editor.md/lib/marked.min.js文件中img标签生成的方法,在
    var out='<img src="'+href+'" alt="'+text+'"';

代码前添加

    if(href.indexOf(':')>0&&href.indexOf("/")<0){href='/lib/exe/fetch.php?cache=&media='+href;}
