前面两个是因为密码不对

第二个说是connect() to unix:/tmp/phpfpm.sock failed 重点是:(13: Permission denied)

后面的错误是因为受到[crit]的影响而来的

这里呢,上次碰到过一次,不过也弄了好久,

这一次有点印象,就很容易找到原因,并且修改回来

开始修改文件了--------------------------

[root@dep5 ~]# vim /usr/local/php/etc/php-fpm.conf

查找phpfpm.sock这一向,发现这个sock在/tmp下面,

[root@dep5 ~]# ll /tmp/phpfpm.sock

rw-rw---- 1 root root 0 9月 1 08:30 /tmp/phpfpm.sock

发现phpfpm.scok的属主属组都是root用户,并且权限为660

而且源码安装PHP和Nginx指定的用户是daemon,daemon,根本没权限查看和修改这个sock文件

解决一方案:

vim /usr/local/php/etc/php-fpm.conf

查找下面那两个

Set permissions for unix socket, if one is used. In Linux, read/write

ermissions must be set in order to allow connections from a web server. Many

BSD-derived systems allow connections regardless of permissions.

Default Values: user and group are set as the running user

mode is set to 0660

listen.owner=****

listen.group=****

将那listen.owner和listen.group注释取消掉,并且改成nginx用户

或者

将 ;listen.mode = 0660 注释取消的,直接改成777得了(^_^)

解决方案二:

chmod 777 /tmp/phpfpm.sock

#PS:我没试过这个方案,但觉得可行,但是这里还有个问题,当把php-fpm重启的时候,权限又被自己改回来了,。。。。。
