添加系统用户

useradd -M -d /data -s /sbin/nologin yeqiang

重启nginx

# /usr/local/nginx/sbin/nginx  -s stop
# /usr/local/nginx/sbin/nginx 

配置测试目录

# mkdir yeqiang-dir
# chown yeqiang:yeqiang^C
# echo a > yeqiang-dir/a
# chown -R yeqiang:yeqiang yeqiang-dir/
# 
# useradd -M -s /sbin/nologin -d /data test
# mkdir test-dir
# echo b > test-dir/b
# chown -R test:test test-dir/ 
# setfacl -R -m u:yeqiang:rwx test-dir/
# chmod -R o-rwx test-dir/
# chmod -R o-rwx yeqiang-dir/
