搭建集群步骤注意事项

节点初始化

     1.时间同步 

     2.防火墙端口开放

     3.系统内核参数优化

 mysql主从操作

       1.mysql创建用户和授权必须要用root用户登录

      2.mysql导出数据库

       3.配置mysql slave端 

       mysql>change master to master_host='192.168.1.102',master_user='slaveuser',master_password='a12345',master_port=3307,master_log_file='mysql-bin.000002',master_log_pos=120;
      

    7.手动初始化数据库数据

 fdfs文件存储服务搭建排错

      1. 启停fdfs服务

    2.检查fdfs服务是否正常

   3.重启服务的步骤

     1.重启fdfs

    2.重启调用fdfs的业务应用

  fastfdfs集成web

        在nginx中给fdfs模块单独配置一个server即可

        要实现HTTP下载必须要求Nginx和fastdfs-nginx-module结合起来

    server {
        listen       8999;
        server_name  localhost;

        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80

        #location ~ \.php$ {

        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;

        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }
