Editor to share with you a case of CentOS using local yum sources to build a LAMP environment, I believe most people do not know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it together.

Configure firewall to open ports 80 and 3306

Vi / etc/sysconfig/iptables

As shown in the figure, add the following two items:

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 80-j ACCEPT # allow port 80 to pass through firewall-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 3306-j ACCEPT # allow port 3306 to pass through firewall

Restart the firewall for the configuration to take effect

/ etc/init.d/iptables restart

Close SELINUX

Vi / etc/selinux/config#SELINUX=enforcing # comment out # SELINUXTYPE=targeted # comment out SELINUX=disabled # add: wq! # Save exit

Restart the system

Shutdown-r now

[install Apache]

Perform installation

Yum-y install httpd

Start Apache

Service httpd restart

Or:

/ etc/init.d/httpd start

After Apache starts, the error Could not reliably determine the server's fully qualifdomain name, using:: 1 for ServerName will be prompted. The solution:

Vi / etc/httpd/conf/httpd.conf

Find # ServerName www.example.com:80

Change to ServerName www.lws.com:80 (set to your own domain name or ServerName localhost:80)

: wqquit # Save exit

Set to boot

Chkconfig httpd on

Check the installation access host address as shown in the figure for successful installation

Modify Apache configuration

Vi / etc/httpd/conf/httpd.conf # it is recommended to use the ftp tool to make a backup before modification

The modifications are as follows:

ServerTokens OS # was modified on line 44 to: ServerTokens Prod (do not display the name of the server operating system when an error page occurs) ServerSignature On # changed to: ServerSignature Off (do not show the version of Apache in the error page) Options Indexes FollowSymLinks # changed to: Options Includes ExecCGI FollowSymLinks (allows the server to execute CGI and SSI Disable listing of directories) # AddHandler cgi-script .cgi # is modified to: AddHandler cgi-script .cgi .pl (allows CGI scripts with .pl extension to run) AllowOverride None # to: AllowOverride All (allow .htaccess) AddDefaultCharset UTF-8 # to: AddDefaultCharset GB2312 (add GB2312 as the default encoding) Options Indexes MultiViews FollowSymLinks # to Options MultiViews FollowSymLinks on line 554 (do not display the tree on the browser) DirectoryIndexindex.html index.html.var # is modified to: DirectoryIndexindex.html index.htm Default.html Default.htm index.php Default.phpindex.html.var (set the default home page file) at line 402 Add index.php) KeepAlive Off # modified to: KeepAlive On (allow programmatic online) MaxKeepAliveRequests100 # at line 83 to: MaxKeepAliveRequests1000 (increase the number of simultaneous connections)

Delete two default test pages

Rm-f / etc/httpd/conf.d/welcome.conf / var/www/error/noindex.html

Restart Apache

Service httpd restart

Or

/ etc/init.d/httpd restart

[install MySQL]

Perform installation

Yum-y install mysql mysql-server

Start MySQL

/ etc/init.d/mysqld start

Set to boot

Chkconfig mysqld on

Copy the configuration file (Note: if there is a my.cnf by default under the / etc directory, you can overwrite it directly)

Cp / usr/share/mysql/my-medium.cnf / etc/my.cnf

Set the password for the root account

Enter mysql_secure_installation#, enter Y according to the prompt, enter the password twice, enter Y all the way according to the prompt, and finally appear: Thanks for using MySQL setting is complete

Or

Mysqladmin-u root password 'password'

Allow remote login

Mysql-u root-p

Enter password

Enter the mysql command:

GRANT ALL PRIVILEGES ON *. * TO 'root'@'%' IDENTIFIED BY' password 'WITH GRANT OPTION

Exit mysql:exit

Restart MySQL

Service mysqld restart

[install PHP5]

Perform installation

Yum-y install php

Install the PHP component (select the following installation package here and enter Y to install according to the prompts)

The copy code is as follows:

Yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt

Modify PHP configuration

Vi / etc/php.ini # it is recommended to use the ftp tool to make a backup before modification

The modifications are as follows:

Date.timezone= PRC # remove the previous semicolon on line 946 and change it to date.timezone= PRC

The copy code is as follows:

Disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server,escapeshellcmd,dll,popen,disk_free_space,checkdnsrr,checkdnsrr,getservbyname,getservbyport,disk_total_space,posix_ctermid,posix_get_last_error,posix_getcwd,posix_getegid,posix_geteuid,posix_getgid,posix_getgrgid,posix_getgrnam,posix_getgroups,posix_getlogin Posix_getpgid,posix_getpgrp,posix_getpid,posix_getppid,posix_getpwnam,posix_getpwuid, posix_getrlimit,posix_getsid,posix_getuid,posix_isatty,posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid,posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname # lists the functions that PHP can disable at line 386 If some programs need to use this function, you can delete it and undisable it.

Expose_php = Off # disable the display of php version information on line 432 magic_quotes_gpc = On # Open magic_quotes_gpc on line 745to prevent SQL injection short_open_tag = On # support php short tag open_basedir =.: / tmp/# on line 380th means allowing access to the current directory (that is, the directory where the PHP script files are located) and / tmp/ directory, which can prevent php Trojans from crossing sites, if there is a problem with the installer after the change You can log out of this line, or write directly to the program's directory / data/www.osyunwei.com/:/tmp/

Restart MySQL, Apahe

Service mysqld restartservice httpd restart

(after completing the yum source to build the LAMP environment, we can check the installation version of each part.)

View Apache version

Httpd-v

View PHP version

Php-v

View MySQL version

Mysql-V
