搭建LAMP环境 用yum安装

安装Apache

安装Apache

[root@localhost /]# yum install httpd httpd-devel

启动Apache

[root@localhost /]# systemctl start httpd

设置Apache开机启动

[root@localhost /]# systemctl enable httpd

Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

数据库安全设置

1. [root@localhost /]# mysql_secure_installation
2. NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
3. SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
4. In order to log into MariaDB to secure it, we'll need the current
5. password for the root user. If you've just installed MariaDB, and
6. you haven't set the root password yet, the password will be blank,
7. so you should just press enter here.
8. Enter current password for root (enter for none):
9. OK, successfully used password, moving on...
10. Setting the root password ensures that nobody can log into the MariaDB
11. root user without the proper authorisation.
12. Set root password? [Y/n] y
13. New password:
14. Re-enter new password:
15. Password updated successfully!
16. Reloading privilege tables..
17. ... Success!
18. By default, a MariaDB installation has an anonymous user, allowing anyone
19. to log into MariaDB without having to have a user account created for
20. them. This is intended only for testing, and to make the installation
21. go a bit smoother. You should remove them before moving into a
22. production environment.
23. Remove anonymous users? [Y/n] y
24. ... Success!
25. Normally, root should only be allowed to connect from 'localhost'. This
26. ensures that someone cannot guess at the root password from the network.
27. Disallow root login remotely? [Y/n] n
28. ... skipping.
29. By default, MariaDB comes with a database named 'test' that anyone can
30. access. This is also intended only for testing, and should be removed
31. before moving into a production environment.
32. Remove test database and access to it? [Y/n] y
33. - Dropping test database...
34. ... Success!
35. - Removing privileges on test database...
36. ... Success!
37. Reloading the privilege tables will ensure that all changes made so far
38. will take effect immediately.
39. Reload privilege tables now? [Y/n] y
40. ... Success!
41. Cleaning up...
42. All done! If you've completed all of the above steps, your MariaDB
43. installation should now be secure.
44. Thanks for using MariaDB!

安装PHP

安装PHP

1. [root@localhost /]# yum -y install php
2. [root@localhost /]# rpm -ql php
3. /etc/httpd/conf.d/php.conf
4. /etc/httpd/conf.modules.d/10-php.conf
5. /usr/lib/httpd/modules/libphp5.so
6. /usr/share/httpd/icons/php.gif
7. /var/lib/php/session

将php与mysql关联起来

1. [root@localhost /]# yum install php-mysql
2. [root@localhost /]# rpm -ql php-mysql
3. /etc/php.d/mysql.ini
4. /etc/php.d/mysqli.ini
5. /etc/php.d/pdo_mysql.ini
6. /usr/lib/php/modules/mysql.so
7. /usr/lib/php/modules/mysqli.so
8. /usr/lib/php/modules/pdo_mysql.so

安装常用PHP模块

[root@localhost /]# yum install -y php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel php-bcmath

测试PHP

1. [root@localhost /]# cd /var/www/html/
2. [root@localhost /]# ls
3. [root@localhost /]# pwd
4. /var/www/html
5. [root@localhost /]# vi info.php
6. <?php
7. phpinfo();
8. ?>
9. ~
10. ~
11. ~
12. ~
13. ~
14. ~
15. ~
16. ~
17. :wq

重启Apache

[root@localhost /]# systemctl restart httpd

测试PHP

更新PHP版本

首先查看是否有老版本

[root@localhost /]# yum list installed | grep php

移除老版本

[root@localhost /]# yum remove php.x86_64 php-cli.x86_64 php-common.x86_64 php-gd.x86_64 php-ldap.x86_64 php-mbstring.x86_64 php-mcrypt.x86_64 php-mysql.x86_64 php-pdo.x86_64

由于linux的yum源不存在php7.x，所以我们要更改yum源：

[root@localhost /]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

[root@localhost /]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

查看yum源中有没有php7.x

1. [root@localhost /]# yum search php7
