LAMP环境搭建+iTop安装（实测使用centos7更方便）

centos 6.7 basic server搭建apache+mariadb+php
Apache
1、ifup ifcfg eth0，配置开机自动启动；
2、setup 设置dns
3、yum install vsftpd
4、修改vsftpd配置文件，两个配置文件中的root用户注释掉；
5、关闭selinux；
# vi /etc/selinux/config
6、修改ftpd服务开机启动启动；
7、上传补丁；
8、打补丁；

下载pcre-8.38.zip
https://sourceforge.net/projects/pcre/files/latest/download
#unzip 10-pcre-8.38
#cd pcre-8.38
# ./configure --prefix=/usr/local/pcre
#make
#make install
#tar -zxvf 11-httpd-2.4.18.tar.gz
#cd httpd-2.4.18
# ./configure --prefix=/usr/local/apache2 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre
#make
#make install

启动Apache：/usr/local/apache2/bin/apachectl start


AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using itop.study. Set the 'ServerName' directive globally to suppress this message
#vi httpd.conf
#ServerName www.xxx.com:80
ServerName localhost:80
:wq
停止Apache：/usr/local/apache2/bin/apachectl stop
重启Apache：/usr/local/apache2/bin/apachectl restart



http://localhost
显示it works! 说明已安装完成。

# vi /etc/rc.local
追加/usr/local/apache2/bin/apachectl start以便开机自动开启apache服务


网站放在/usr/local/apache2/htdocs下；


如果网站的index后缀名是php的，则需要在/usr/local/apache2/conf/httpd.conf文件夹，增加index.php。
# DirectoryIndex: sets the file that Apache will serve if a directory
# is requested.
#
<IfModule dir_module>
    DirectoryIndex index.html index.php
</IfModule>


参考网页：
http://www.cnblogs.com/zhuque/archive/2012/11/03/2763352.html#
另：Linux下apache服务启动后，本机能正常访问，但局域网内其他机器无法访问
1、打开终端；
2、#setup
3、选择【firewall configuration】；
4、选择下面的【customise】；
5、找到并选择【www(http)】，关闭即可。

Filling help tables...
1602270:23:47 ./bin/mysqld (mysqld 5.5.48-MariaDB) starting as process 1112 ...OK


To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

#cp support-files/mysql.server /etc/init.d/



PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:



启动数据库：
#/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf --datadir=/usr/local/mysql/data --user=mysql &



'./bin/mysqladmin' -u root password 'new-password'
'./bin/mysqladmin' -u root -h php.myfamily password 'new-password'


Alternatively you can run:
'./bin/mysql_secure_installation'


which will also give you the option of removing the test
databases and anonymous user created by default.This is
strongly recommended for production servers.


See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.


You can start the MariaDB daemon with:
cd '.' ; ./bin/mysqld_safe --datadir='/var/lib/mysql'


You can test the MariaDB daemon with mysql-test-run.pl
cd './mysql-test' ; perl mysql-test-run.pl


Please report any problems at http://mariadb.org/jira
