# 安装
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server
# 启动
systemctl start  mysqld.service 
# 状态
systemctl status mysqld.service
# 找密码 G9hLnliLXd?p
grep "password" /var/log/mysqld.log
# 进入root
mysql -uroot -p
# 修改密码 降低复杂难度
mysql> set global validate_password_policy=0;
mysql> set global validate_password_length=1;
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'password';
# del Yum Repository
yum -y remove mysql57-community-release-el7-10.noarch

vim /etc/ssh/sshd_config

#将 #PermitRootLogin yes 这一行的注释去掉#，这样就可以允许远程连接了

# 重启ssh服务：

systemctl restart sshd
systemctl status sshd （能查看到服务正常了）
# 此时应该就可以远程连接服务器了，如果还不能连接，有如下提示：

#ECDSA host key “ip地址” for has changed and you have requested strict checking

ssh-keygen -R “你的远程服务器ip地址”

1. 下载NImg
wget https://github.com/ofpay/nimg/archive/master.zip -O nimg.zip

2. 解压刚才下载的文件nimg.zip
 unzip nimg.zip

3.安装依赖模块组
  cd nimg-master
  npm install

4.修改配置，确保图片存储以及上传目录有足够的权限
vi config.js

exports.tmproot='/node/temp'; //上传临时目录，
exports.imgroot='/node/img'; //图片存储目录，
exports.errorlog='/node/log/error.log'; //程序错误日志，记录
exports.port=9000;  //http端口号
exports.appname='NImg';
exports.maxFileSize=1024*1024;//上传最大限制单位字节 1024kb 1mb
exports.maxSide=800; //最大截图边长
exports.minSide=30; //最小截图边长
 
//支持图像文件类型
exports.imgtypes={
        "gif": "image/gif",
        "jpeg": "image/jpeg",
        "jpg": "image/jpeg",
        "png": "image/png"
};
 

5.启动
sh nimg.sh start

6.查看控制台输出
taillf nohup.out

7.关闭
sh nimg.sh stop

# nimg 压缩convent图片 缺少ImageMagick 巨坑
yum install -y libjpeg* libpng* libtiff* libungif* freetype zlib
wget https://www.imagemagick.org/download/ImageMagick.tar.gz
tar zxvf ImageMagick.tar.gz
cd ImageMagick.tar.gz
./configure
make
make install
ldconfig /usr/local/lib
检测是否成功 convert -version

一定一定要先测试上传 有坑

Error: Buffer.write(string, encoding, offset[, length]) is no longer supported #6
package.json 里边 改下express版本， “express”: “3.21.2”
