关于nginx报错/usr/share/nginx/html/jiankongshare" failed ，2: No such file or directory的问题解决
monitor.conf
server {
server_name monitor.chinasoft.com;
server_name 1.1.1.1;
error_log /data/logs/web-acccess.log info;
access_log /data/logs/web-error.log;
location /jiankongshare{

proxy_set_header X-Real-Ip $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_pass http://localhost:8082/;#正式服务器地址
}
}
访问1.1.1.1/jiankongshare报错如下：

分析：
nginx还是默认到
/usr/share/nginx/html/jiankongshare 这个根目录下去找我们的html文件，通过修改default.conf及nginx.conf的根目录也无法改变目录的配置，重启无效
其实有两台nginx做负载均衡，另外一台是ok的最后不得已直接删除nginx，重新安装，发现问题解决
解决办法：
关闭服务service nginx stop
删除nginx
rpm -e --nodeps nginx-1.10.2-1.el6.x86_64
重新安装
yum install -y nginx
再次修改配置，启动nginx，再次访问1.1.1.1/jiankongshare 发现问题解决
