Today Xiaobian to share with you CentOS using local yum source to build LAMP environment related knowledge points, detailed content, clear logic, I believe most people still know too much about this knowledge, so share this article for everyone to refer to, I hope you read this article after harvest, let's learn about it together.

[Preparations]

Configure firewall, open port 80 and port 3306

vi /etc/sysconfig/iptables

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

-a input -m state --state new -m tcp -p tcp --dport 80 -j accept #Allow port 80 through firewall-a input -m state --state new -m tcp -p tcp --dport 3306 -j accept #Allow port 3306 through firewall

Restart firewall to make configuration 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 the installation

yum -y install httpd

start Apache

service httpd restart

Or:

/etc/init.d/httpd start

Apache could not reliably determine the server's fully qualifdomain name, using ::1 for servername

vi /etc/httpd/conf/httpd.conf

Find #servername www.example.com:80

Modify to servername www.lws.com:80 (set to own domain name or servername localhost:80)

:wq!# save and exit

Set to boot

chkconfig httpd on

Check the installation access host address as shown in the figure. Installation is successful

Modify apache configuration

vi /etc/httpd/conf/httpd.conf #It is recommended to make a backup before using ftp tool to modify

Amend as follows:

servertokens os #on line 44 modified to: servertokens prod (Do not display the name of the server operating system when the error page appears) serversignature on #Modified to: serversignature off at line 536 options indexes followsymlinks #on line 331 changed to: options includes execcgi followsymlinks #addhandler cgi-script .cgi #modified to: addhandler cgi-script.cgi .pl on line 796 (Allow cgi scripts with extension.pl to run) allowoverride none #modified to: allowoverride all on line 338 (Allow.htaccess) adddefaultcharset utf-8 #modified to read: adddefaultcharset gb2312 (gb2312 added as default) options indexes multiviews followsymlinks #modified to options multiviews followsymlinks on line 554 (Not displaying tree structure in browser) directoryindex.html index.html.var #modified to: directoryindex.html index.htm default.html index.php default.phpindex.html.var on line 402 (Set default home page file, add index.php) keepalive off #in line 76 modified to: keepalive on (allow programmatic connection) maxkeepaliverequests 100 #in line 83 modified to: maxkeepaliverequests1000 (increase the number of simultaneous connections)

Remove 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 the installation

yum -y install mysql mysql-server

start the 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 password for root account

mysql_secure_installation#Enter, enter y according to prompt, enter password twice, enter, enter y all the way according to prompt, and finally appear: thanks for using mysql

or

mysqladmin -u root password 'password'

Allow remote login

mysql -u root -p

enter the 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 the installation

yum -y install php

Install php components (here select the following installation package, enter y to install according to the prompt)

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 make a backup before modifying it with ftp tool

Amend as follows:

date.timezone= prc #Remove the semicolon at 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_streror,posix_times,posix_ttyname,posix_uname #List the functions that php can disable in line 386. If some programs need this function, you can delete it and undisable it.

expose_php = off #Disable php version information on line 432 magic_quotes_gpc = on #Open magic_quotes_gpc on line 745 to prevent sql injection short_open_tag = on #Support php short tag open_basedir = .:/on line 229 tmp/#is set in line 380 to allow access to the current directory (that is, the directory where the php script file is located) and/tmp/directory, which can prevent php Trojans from crossing sites. If there is a problem with installing the program after changing it, you can log off this line, or write directly to the program directory/data/www.osyunwei.com/:/tmp/

Restart mysql, apahe

service mysqld restartservice httpd restart

(This completes the yum source lamp environment, we can check the installation version of each part)

View Apache version

httpd -v

View php version

php -v

Check out the MySQL version

mysql -v
