CentOS 6.4 installation and configuration LAMP server (Apache+PHP5+MySQL)

Preparation:

1. Configure the firewall and open port 80 and 3306
vi /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT #Allow port 80 Through the firewall
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT #Allow port 3306 through the firewall

As shown below:
############################ After adding, the firewall rules will look as follows###### #######################
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp - j ACCEPT
-A INPUT -i lo -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp- host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited

/etc/init.d/iptables restart #Finally restart the firewall to make the configuration take effect

2. Turn off SELINUX
vi /etc/selinux/config

Change to ServerName www.osyunwei.com:80 #Set it to your own domain name here. If there is no domain name, you can set it to localhost
:wq! #Save and exit
chkconfig httpd on #Set to start at boot
/etc/init.d/httpd restart #Restart Apache

2. Install MySQL

/etc/init.d/mysqld start #Start MySQL
chkconfig mysqld on #Set To start up
cp /usr/share/mysql/my-medium.cnf /etc/my.cnf #Copy the configuration file (Note: If there is a my.cnf under the /etc directory by default, just overwrite it directly)

2. Set the password for the root account
mysql_secure_installation
Press Enter, enter Y according to the prompts
Enter the password twice, press Enter
Enter Y all the way according to the prompts
Finally, the following message appears: Thanks for using MySQL!

2. PHP configuration
vi /etc/php.ini #Edit
date.timezone = PRC #On line 946, remove the semicolon in front and change it to date.timezone = PRC
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

#On line 386, list the functions that can be disabled in PHP. If some programs need to use this function, it can be deleted and undisabled.
expose_php = Off #Suppress display of php version information on line 432
magic_quotes_gpc = On #Turn on magic_quotes_gpc on line 745 to prevent SQL injection
short_open_tag = ON #Support php short tags on line 229
open_basedir = .:/tmp / # Setting on line 380 means allowing access to the current directory (that is, the directory where the PHP script file is located) and the /tmp/ directory, which can prevent PHP Trojans from crossing the site. If there is a problem with the installation program after changing it (for example: DreamWeaver Content Management system), you can log out of this line, or write directly to the program directory /data/www.osyunwei.com/:/tmp/
:wq! #Save and exit
