Apache http Server 2.4 效能解放

Apache 2.4 宣佈已經可以跟 Nginx比拼了
但很多網路文章卻測不出這個效能

一開始我也沒辦法解放它的效能
經過數次的安裝移除的循環
發現一個重要的參數: --with-mpm
必須安裝為 event Multi-Processing Module
這就是解放效能的所在囉

什麼是 event module， 其實就是 linux EPoll，Nginx 也是應用這個模式


Apache 2.4 安裝步驟

#安裝 APR
tar -zxvf apr-1.4.6.tar.gz
cd apr-1.4.6
./configure --prefix=/usr/local/apache-apr --enable-nonportable-atomics=yes
make
sudo make install

#安裝 APR-UTIL apr-util
tar -zxvf apr-util-1.4.1.tar.gz
cd apr-util-1.4.1
./configure --prefix=/usr/local/apache-apr --with-apr=/usr/local/apache-apr
make
sudo make install

unzip -o pcre-8.30.zip
cd pcre-8.30
./configure --prefix=/usr/local/pcre --enable-utf --enable-unicode-properties
make
sudo make install

#安裝 apache server
1. tar -zxvf httpd-2.4.2.tar.gz

2. cd httpd-2.4.2

3. ./configure --prefix=/usr/local/apache2.4 --with-apr=/usr/local/apache-apr --with-apr-util=/usr/local/apache-apr --with-pcre=/usr/local/pcre --with-mpm=event \
--enable-nonportable-atomics=yes \
--enable-mods-shared=all \
--enable-expires=shared \
--enable-headers=shared \
--enable-reqtimeout=shared \
--enable-ssl=shared \
--enable-rewrite=shared \
--enable-speling=shared \
--enable-proxy=shared \
--enable-proxy-connect=shared \
--enable-proxy-ajp=shared \
--enable-proxy-balancer=shared \
--enable-proxy-express=shared \
--enable-info=shared \
--enable-heartbeat=shared \
--enable-heartmonitor=shared \
--enable-ratelimit=shared \
--enable-remoteip=shared \
--enable-allowmethods=shared

4. make

5. sudo make install

6.Check Apache MPM 是 event
/usr/local/apache2.4/bin/httpd -l
/usr/local/apache2.4/bin/httpd -V | grep MPM

#效能調整
#修改 httpd-mpm.conf 下的mpm_event_module

    StartServers             2
    MinSpareThreads         25
    MaxSpareThreads         75
    ThreadsPerChild         25
    MaxRequestWorkers      150
    MaxConnectionsPerChild   0

利用 Ghostscript 重新產生PDF

Ghostscript
http://pages.cs.wisc.edu/~ghost/


完整參數
http://www.ghostscript.com/doc/current/Use.htm


範例指令

 轉換為600dpi
 gswin32c -dNOPAUSE -dBATCH -q -r600 -sDEVICE=pdfwrite -sOutputFile=out.pdf input.pdf

指定頁數
gswin32c -dNOPAUSE -dBATCH -q -r600 -sDEVICE=pdfwrite -dFirstPage=22 -dLastPage=36 -sOutputFile=out.pdf input.pdf

pdfwrite Additional Options

 -dPDFSETTINGS=/ebook    (low quality, 150 dpi images)
 -dPDFSETTINGS=/printer  (high quality, 300 dpi images)
 -dPDFSETTINGS=/prepress (high quality, color preserving, 300 dpi imgs)

Paper size selection options
 -sPAPERSIZE=letter
 -sPAPERSIZE=a4
 -dDEVICEWIDTHPOINTS=w -dDEVICEHEIGHTPOINTS=h (point=1/72 of an inch)
 -dFIXEDMEDIA (force paper size over the PostScript defined size)

Other options
 -dEmbedAllFonts=true
 -dSubsetFonts=false
 -dFirstPage=pagenumber
 -dLastPage=pagenumber
 -dAutoRotatePages=/PageByPage
 -dAutoRotatePages=/All
 -dAutoRotatePages=/None
 -r1200 (resolution for pattern fills and fonts converted to bitmaps)
 -sPDFPassword=password
 -dConvertCMYKImagesToRGB=true
 -dCompatibilityLevel=1.5

更多參數請參考 Ps2pdf.htm

讓Ext JS 2 支援IE9

增加下列語法即可

if (typeof Range.prototype.createContextualFragment == "undefined") {
    Range.prototype.createContextualFragment = function(html) {
        var doc = this.startContainer.ownerDocument;
        var container = doc.createElement("div");
        container.innerHTML = html;
        var frag = doc.createDocumentFragment(), n;
        while ( (n = container.firstChild) ) {
            frag.appendChild(n);
        }
        return frag;
    };
}

GraphicsMagick 安裝

GraphicsMagick 據說效能比 ImageMagick好，是ImageMagick的分支

安裝說明網頁

./configure --with-quantum-depth=8 (8、16、32 數字越低，轉圖效率越高)

--with-gslib=yes

--disable-openmp (開閉OpenMP)

--enable-shared

顯示有缺套件時需自行安裝

yum install libjpeg libjpeg-devel zlib zlib-devel libpng libpng-devel bzip2 bzip2-devel lcms lcms-devel librsvg2 librsvg2-devel libxml2 libxml2-devel libtiff libtiff-devel libwmf libwmf-devel libXau libXau-devel

ImageMagick pdf to jpg

安裝 ImageMagick

安裝 ghostscript (PDF 額外套件)，未安裝會出現 error/pdf.c/ReadPDFImage 錯誤

unix 環境

1. ghostscript-8.70.tar.gz
2. ghostscript-fonts-std-8.11.tar.gz 解壓縮到 /usr/local/share/ghostscript/fonts

windows 環境

1. gs871w32.exe
2. 設定path C:\Program Files\gs\gs8.71\bin

執行指令即可轉換檔案 convert -verbose 1.pdf 1.jpg

OpenOffice service

一般網路上的教學都是使用下列指令
soffice -headless -accept="socket,host=localhost,port=8100;urp;StarOffice.Service" -nofirststartwizard

但如果使用非管理者的帳號啟動上列指令，可能會發生部分目錄下的轉檔失敗。
可以改用下列指令啟動
soffice.bin -accept="socket,host=localhost,port=8100;urp;StarOffice.Service" -headless
-nofirststartwizard

outputParams.add(call.invoke(inputParams));

//取得剩餘的回傳值
outputParams.addAll(call.getOutputValues());
