三臺主機
1 yum安裝
[mariadb]
name = MariaDB
baseurl = https://mirrors.tuna.tsinghua.edu.cn/mariadb/mariadb-5.5.60/yum/centos7-amd64/
gpgcheck=0

httpd2.2

order deny,allow

allow from 192.168.30.6
deny from 192.168.30.0/24

</IfModule>

#
# Control access to UserDir directories. The following is an example
# for a site where these directories are restricted to read-only.
#
#<Directory “/home/*/public_html”>
# AllowOverride FileInfo AuthConfig Limit Indexes
# Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
# Require method GET POST OPTIONS
#</Directory>

<directory /home/wang/public_html>
authType Basic
AuthName “wang home dir”
AuthUserFile “/etc/httpd/conf.d/.httpuser”
AuthGroupFile “/etc/httpd/conf.d/.httpgroup”
Require group g1
</directory>
