簡述
zimg是圖像存儲和處理服務器。您可以使用URL參數從zimg獲取壓縮和縮放的圖像。
zimg的並發I / O，分布式存儲和時間處理能力非常出色。
您不再需要在圖像服務器中使用nginx。在基准測試中，zimg可以在高並發級別上處理每秒3000+圖像下載任務和每秒90000+ HTTP回應請求。
性能高於PHP或其他圖像處理服務器。
安裝依賴庫
sudo yum install -y wget openssl-devel cmake libevent-devel libjpeg-devel giflib-devel libpng-devel libwebp-devel ImageMagick-devel libmemcached-devel
sudo yum install -y glibc-headers gcc-c++
sudo yum install -y build-essential nasm
安裝依賴（比較多）
openssl

tar xzvf cmake-3.0.1.tar.gz
cd cmake-3.0.1
./bootstrap --prefix=/usr/local
make && make install
libevent
mkdir -p /usr/local/zimg/libevent
cd /usr/local/zimg/libevent
wget http://cloud.github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
tar zxvf libevent-2.0.21-stable.tar.gz
cd libevent-2.0.21-stable
./configure --prefix=/usr/local
make && make install
libjpeg-turbo
mkdir -p /usr/local/zimg/libjpeg-turbo
cd /usr/local/zimg/libjpeg-turbo
wget https://downloads.sourceforge.net/project/libjpeg-turbo/1.3.1/libjpeg-turbo-1.3.1.tar.gz
tar zxvf libjpeg-turbo-1.3.1.tar.gz
cd libjpeg-turbo-1.3.1
./configure --prefix=/usr/local --with-jpeg8
make && make install
webp
mkdir -p /usr/local/zimg/webp
cd /usr/local/zimg/
wget http://downloads.webmproject.org/releases/webp/libwebp-0.4.1.tar.gz
tar zxvf libwebp-0.4.1.tar.gz
cd libwebp-0.4.1
./configure
make
sudo make install
jpegsrc
mkdir -p /usr/local/zimg/jpegsrc
cd /usr/local/zimg/
wget http://www.ijg.org/files/jpegsrc.v8b.tar.gz
tar -xf jpegsrc.v8b.tar.gz
cd jpeg-8b
./configure --prefix=/usr/local --enable-shared --enable-static
make && make install
imageMagick
mkdir -p /usr/local/zimg/imageMagick
cd /usr/local/zimg/
wget http://www.imagemagick.org/download/ImageMagick.tar.gz
tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.9.1-10
./configure --prefix=/usr/local
make && make install
libmemcached
mkdir -p /usr/local/zimg/libmemcached
cd /usr/local/zimg/
wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz
tar zxvf libmemcached-1.0.18.tar.gz
cd libmemcached-1.0.18
./configure -prefix=/usr/local
make && make install
構建zimg
cd /usr/local/zimg
##此處不要根據下面鏈接去下載，自己去zimg github地址庫區下載最新 版；
#git clone https://github.com/buaazp/zimg -b master --depth=1
# github：https://github.com/buaazp/zimg
cd zimg
make
安裝成功后
cd /usr/local/zimg/zimg/bin
./zimg conf/zimg.lua
ctrl+z 退出
curl http://localhost:4869
如果出現html代碼 則說明安裝啟動成功。
然后可以直接訪問http://localhost:4869 ，如果訪問失敗可以查看防火牆端口是否開啟。
可能會出現的錯誤
安裝zimg最后一步make時報錯make[1]: 進入目錄“/usr/local/zimg/deps/libjpeg-turbo” make[1]: ***
解決方法：
yum install libtool –y
Centos 7 firewall 命令
查看已經開放的端口：
firewall-cmd --list-ports
開啟端口
firewall-cmd --zone=public --add-port=80/tcp --permanent
命令含義：
–zone #作用域
–add-port=80/tcp #添加端口，格式為：端口/通訊協議
–permanent #永久生效，沒有此參數重啟后失效
重啟防火牆
firewall-cmd --reload #重啟firewall
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall開機啟動
firewall-cmd --state #查看默認防火牆狀態（關閉后顯示notrunning，開啟后顯示running）
Python調用上傳接口
img_path = "C:\\Users\\Administrator\\Desktop\\centos7.jpg"
url = 'http://127.0.0.1:4869/upload'
files = {'file': ('centos7.jpg', open(img_path, 'rb'), 'image/jpeg')}
rsp = requests.post(url, files=files)
print(rsp.text)
