: In linux httpd server, how does one configure user authentication in the CONF file?
　　
: In-service ACCESS. It seems that there is no response in CONF,
　　
: For example, ACCESS. Setting deny from all in CONF seems useless !!
　　
: I want to know how to ensure that only LINUX users can access HTTPD SERVER.
　　
: (Or a group)
　　
Access and user authentication in httpd can be performed in the global or directory, or at the same time.
　　
The default file for server control is access. conf. Generally, only sysop has the right to change the directory access control. htaccess (available in srm. conf), because everyone can create. htaccess. you can set up access control for your own directories .. Because the two
　　
The method is similar. the following only describes the access. conf file: # The following is an explanation.
　　
　　
　　
Options shortdes # allow SSI
　　
AuthType Basic # it seems that this type is supported now
　　
AuthName "Ali's Homepage"
　　
AuthUserFIle/home/www/ali/. htpasswd # User passwd file
　　
AuthGroupFile/home/www/ali/. htpgroup # User Group file
　　
　　
　　
# Restrict access to hosts
　　
Order deny, allow
　　
Allow from gzsums.edu.cn
　　
Deny from all
　　
# Deny from all reject all
　　
# Restrict access to users,
　　
Require user ali, last
　　
# Allow ali and last access to this directory # require user valid-user includes all users in. htpasswd
# Host-based control priority is higher than user-based # so... this directory is accessible only when ali and last are in * .gzsums.edu.cn.
　　
　　
　　
　　
　　
. Htpasswd is created using the htpasswd command. check whether the directory is correct. ps-ax checks the httpd PID, and kill-1 PID.
　　
Enjoy it.
