linux下布置php项目-Apache、php、mysql关联
分类:电脑系统

  linux下部署php项目环境可以分为两种,一种使用Apache,php,mysql的压缩包安装,一种用yum命令进行安装。

使用三种软件的压缩包进行安装,需要手动配置三者之间的关系。apache和php之间的配置没有什么难度,但是和mysql进行配置的时候就需要对php的了解了。

以下是用yum在linux中配置php环境:

 

MySql

 

  1.mysql和apache最好是首先进行安装的,因为在配置php的时候需要与mysql和apache进行关联配置和测试

首先下载mysql-sever文件,因为博主linux环境是CentOS版本,yum源中貌似没有正常安装mysql时的mysql-sever文件,需要去官网上下载

1.下载mysql-service文件

[root@tele-1 ~]# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

2.安装mysql-service文件

[root@tele-1 ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm

 

   2.安装mysql

[root@tele-1 ~]# yum install mysql-community-server

 

   3.安装完毕之后启动mysql服务

[root@tele-1 ~]# service mysqld restart

 

  4. 初步安装的mysql是没有密码的,用户名默认是root。所以我们需要修改密码,用mysql命令行进行修改

 1.进入mysql命令行

[root@tele-1 ~]# mysql -uroot
Welcome to the MySQL monitor.  Commands end with ; or g.
Your MySQL connection id is 474801
Server version: 5.6.36 MySQL Community Server (GPL)

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

mysql> 

2.使用命令进行密码修改

mysql> set password for 'root'@'localhost' = password('你要修改的密码');
Query OK, 0 rows affected (0.06 sec)

 

  5.因为博主是用本地navicat软件来连接linux下的mysql的,所以如果要在本地访问的话,就需要改一下mysql数据库中的user表了

1.操作mysql数据库表

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> 


2.查看user表中的数据(在mysql命令行中可以直接进行sql语句编写)

mysql> select * from user;

5 rows in set (0.00 sec)

mysql> 

 

  3.博主的表中是修改之后的表了,想要远程访问,就需要上边红色标注的数据了,Host指的是可以访问此数据库的ip地址,%代表的是所有的请求都可以连接进来。

大家可以修改一条数据,也可以添加一条数据。但是最好不要修改上边蓝色标注的数据,修改语句就是下边的格式

mysql> update user set Host = '%' where ???

 

  4.最后推出exit或者q都是退出mysql命令行的方法

mysql> q
Bye

 

 

 

 安装Apache

 

  1.apache安装方法相对简单

[root@tele-2 ~]# yum install httpd

 

  2.外网访问虚拟机中的地址,我们就需要修改一下apache的配置文件/etc/httpd/conf/httpd.conf

 

图片 1

 找到  #ServerName www.example.com:80            改为  ServerName localhost:80

   如右图所示:

 

 

 

 

图片 2

 找到  #Listen                                 改为  Listen:8080(linux中开放的端口号80XX)

 如右图所示:

   

 

 

 

 

 

  

  3.修改完成之后我们需要再次启动httpd服务,并查看启动状态

[root@tele-2 ~]# service httpd start
Redirecting to /bin/systemctl start  httpd.service
[root@tele-2 ~]# service httpd status
Redirecting to /bin/systemctl status  httpd.service
● httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
   Active: active (running) since Mon 2017-06-05 15:57:34 CST; 5s ago
     Docs: man:httpd(8)
           man:apachectl(8)
  Process: 54532 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=0/SUCCESS)

           ├─54576 /usr/sbin/httpd -DFOREGROUND
           ├─54577 /usr/sbin/httpd -DFOREGROUND
           ├─54578 /usr/sbin/httpd -DFOREGROUND
           ├─54579 /usr/sbin/httpd -DFOREGROUND
           └─54580 /usr/sbin/httpd -DFOREGROUND

Jun 05 15:57:34 tele-2 systemd[1]: Starting The Apache HTTP Server...
Jun 05 15:57:34 tele-2 systemd[1]: Started The Apache HTTP Server.

 

  4.此时你就可以访问你的服务器了,输入localhost或者ip地址,出现一个Apache test page powered by centos的测试页面

 

PHP

 

  1.php安装命令

[root@tele-2 ~]# yum install php

 

  2.直接一路安装,安装完成之后再次重启httpd服务

[root@tele-2 ~]# service httpd start
Redirecting to /bin/systemctl start  httpd.service

 

  3.重启之后我们进行测试PHP相关信息,我们新建一个PHP界面进行测试

在apache默认页面路径/``var``/www/html下新建一个test.php页面,添加代码

<?php
 phpinfo();
?>

     

图片 3

 

  4.访问这个页面,输入localhost/test.php,或者

ip:端口号/test.php就可以看见php环境的配置信息了。如右图:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

关联php和mysql

 

  1.搜索模块

[root@tele-2 ~]# yum search php

 

  2.安装相关模块

[root@tele-2 ~]# yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml  php-xmlrpc

 

图片 4

  3.安装完成,重启mysqld,重启httpd

重新访问刚才的info.php,我们发现已经多了MySQL的相关信息。如右图:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

   至此,php在linux中的运行环境就已经成功配置完成了。

 

  1.mysql yum安装默认文件夹及相关命令

数据库目录:/var/lib/mysql/

配置文件:/usr/share/mysql(mysql.server命令及配置文件)

相关命令:/usr/bin(mysqladmin mysqldump等命令)

my.cnf: /etc/my.cnf

启动脚本:/etc/rc.d/init.d/(启动脚本文件mysql的目录)

启动命令:service mysql start

停止命令:service mysql stop

运行状态:service mysql status

 

 

  2.apache

配置文件路径:/etc/httpd/conf/httpd.conf

启动命令:service httpd start

停止命令:service httpd stop

运行状态:service httpd status

 

 

  3.php

php默认页面路径:/var/www/html
