初始化CentOS LAMP，記錄一下過程：
一、安裝apache
[root@syslog01 axing]# yum install httpd -y
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: mirror.sov.uk.goscomb.net
#過程略...
Installed:
httpd.x86_64 0:2.4.6-88.el7.centos
Dependency Installed:
apr.x86_64 0:1.4.8-3.el7_4.1 apr-util.x86_64 0:1.5.2-6.el7
httpd-tools.x86_64 0:2.4.6-88.el7.centos mailcap.noarch 0:2.1.41-2.el7
Complete!
啓動httpd服務
[root@syslog01 axing]# systemctl start httpd.service
設置開機啓動
[root@syslog01 axing]# systemctl enable httpd.service
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
2、安裝數據庫。這裏安裝的是MariaDB，MariaDB數據庫是MySQL的一個分支，完全兼容MySQL，包括API和命令行。
[root@syslog01 axing]# yum -y install mariadb-server mariadb
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
#過程略...
Installed:
mariadb-server.x86_64 1:5.5.60-1.el7_5 mariadb.x86_64 1:5.5.60-1.el7_5
Dependency Installed:
perl-DBD-MySQL.x86_64 0:4.023-6.el7
Complete!
啓動數據庫服務
[root@syslog01 axing]# systemctl start mariadb.service
設置開機啓動
[root@syslog01 axing]# systemctl enable mariadb.service
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
數據庫安全設置，包括設置root密碼，禁止root遠程登錄，移除匿名用戶和測試數據庫等，可選項：
[root@syslog01 axing]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
[root@syslog01 axing]#
3、安裝PHP
安裝PHP，這裏用yum install安裝的是PHP Version 5.4.16
[root@syslog01 axing]# yum -y install php
安裝常用模塊
[root@syslog01 axing]# yum -y install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel
關聯php與數據庫
[root@syslog01 axing]# yum -y install php-mysql
想簡單看到PHP版本，可以在/var/www/html/目錄下創建一個info.php文件，用vi/vim什麼的也都行，待會用。
[root@syslog01 axing]# echo "<?php phpinfo(); ?>" > info.php
4、防火牆設置
開放防火牆80端口。如果不喜歡firewall的話，關掉安裝ufw也挺好，我ubuntu用的多，更習慣用ufw
[root@syslog01 axing]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success
···
[root@syslog01 axing]# firewall-cmd --reload
success
#關閉 selinux
[root@syslog01 axing]# setenforce 0
重啓httpd
[root@syslog01 axing]# systemctl restart httpd.service
5、驗證
在瀏覽器裏輸入服務器ip地址，會顯示類似下面信息表示httpd正常運行：
輸入http://<IP Address>/info.php，則可以看到PHP信息
完工，快照一下，然後開心的繼續安裝其他服務去了。
