Httpd implements the simple function of http

Httpd implements user access control:

(1) define a security domain

Control based on a single user: Options None AllowOverride None AuthType Basic AuthName "String" AuthUserFile "/ etc/httpd/conf/.httpdpasswd" AuthGroupFile "/ etc/httpd/conf/.grp" Require ip 172.20 Require user ops1

Control based on user groups:

Options NoneAllowOverride NoneAuthType BasicAuthName "String" AuthUserFile "/ etc/httpd/conf/.httpdpasswd" AuthGroupFile "/ etc/httpd/conf/.grp" Require ip 172.20 Require group ops

(2) provide account number and password storage (text file)

Use special commands to complete the creation and user management of such files.

Htpasswd [options] / PATH/TO/HTTPD_PASSWD_FILE username-c: automatically creates the file specified here, so it should be used only if this file does not exist -m:md5 format encryption-s: sha format encryption-D: delete specified user-b: batch mode add user [root@localhost conf] # htpasswd-bc / etc/httpd/conf/.httppasswd ops1 123456Adding password for user ops1 [root@localhost conf] # vim / etc/httpd/conf/.grpops:ops1 ops2

(3) restart the test:

[root@localhost conf.d] # systemctl restart httpd

two。 Configuration of virtual host

(1) Virtual host based on IP address

[root@localhost /] # mkdir / data/html/ {a B}-pvmkdir: created directory'/ data/html'mkdir: created directory'/ data/html/a'mkdir: created directory'/ data/html/b' [root@localhost /] # vim / data/html/a/index.htmlhello a [root@localhost /] # vim / data/html/b/index.htmlhello b [root@localhost conf.d] # vim vhost_ip.conf ServerName www.a.com DocumentRoot "/ data/html/a/" Options None AllowOverride None Require all granted ServerName www.b.com DocumentRoot "/ data/html/b/" Options None AllowOverride None Require all granted

(2) Port-based virtual host:

[root@localhost conf.d] # vim vhost_ip.conf Listen 8080 ServerName www.a.com DocumentRoot "/ data/html/a/" Options None AllowOverride None Require all granted ServerName www.b.com DocumentRoot "/ data/html/b/" Options None AllowOverride None Require all granted

(3) Virtual host based on FQDN:

[root@localhost conf.d] # vim vhost_ip.conf ServerName www.a.com DocumentRoot "/ data/html/a/" Options None AllowOverride None Require all granted ServerName www.b.com DocumentRoot "/ data/html/b/" Options None AllowOverride None Require all granted

Note: in the case of httpd-2.2, when using a FQDN-based virtual host, you need to use the following instructions in advance: NameVirtualHost IP:PORT

3. Implement https

[root@localhost conf.d] # yum install-y mod_ssl

(1) build a private CA:

Generate a private key; ~] # (umask 077; openssl genrsa-out / etc/pki/CA/private/cakey.pem 4096) generate a self-signed certificate; ~] # openssl req-new-x509-key / etc/pki/CA/private/cakey.pem-out / etc/pki/CA/cacert.pem-days 3655-new: generate a new certificate signing request;-x509: generate a self-signed certificate dedicated to creating a private CA;-key: the private file path used to generate the request -out: the generated request file path; if the self-signed operation will directly generate the signed certificate;-days: the validity period of the certificate, in day;, the directories and files required for CA; ~] # mkdir-pv / etc/pki/CA/ {certs,crl,newcerts} ~] # touch / etc/pki/CA/ {serial,index.txt} ~] # echo 01 > / etc/pki/CA/serial

(2) the server that uses the certificate for secure communication needs to request the CA to sign the certificate.

The host that uses the certificate generates the private key; ~] # mkdir / etc/httpd/ssl~] # cd / etc/httpd/ssl~] # (umask 077; openssl genrsa-out / etc/httpd/ssl/httpd.key 2048) generates the certificate signing request ~] # openssl req-new-key / etc/httpd/ssl/httpd.key-out / etc/httpd/ssl/httpd.csr-days 365 sign the certificate on the CA host ~] # openssl ca-in / etc/httpd/ssl/httpd.csr-out / etc/pki/CA/certs/httpd.crt-days 365 [root@localhost /] # vim / etc/httpd/conf.d/ssl.conf DocumentRoot "/ data/html/b/" ServerName www.b.com:443SSLCertificateFile / etc/httpd/ssl/httpd.csrSSLCertificateKeyFile / etc/httpd/ssl/httpd.key Options None AllowOverride None Require all granted
