How to deploy php project environment under linux system

This article introduces to you how to deploy the PHP project environment under the Linux system. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

The environment for deploying PHP projects under Linux can be divided into two types, one is installed using the compressed package of Apache, PHP, and MySQL, and the other is installed using the yum command.

Use the compressed packages of the three software to install, and you need to manually configure the relationship between the three. The configuration between apache and php is not difficult, but when configuring with mysql, you need to understand php.

The following is to use yum to configure the php environment in linux:

Install MySql

1 .mysql and apache are best installed first, because when configuring php, they need to be configured and tested in conjunction with mysql and apache.

First download the mysql-sever file, because the blogger's Linux environment is the CentOS version. It seems that there is no mysql-sever file for normal installation of mysql in the yum source. You need to download it from the official website

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

2. Install mysql

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

3. After the installation is completed, start the mysql service

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

4. The initial installation of mysql does not have a password, and the default user name is root. So we need to change the password and use the mysql command line to change it

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

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. Because the blogger uses the local navicat software to connect to mysql under Linux, so if you want to access it locally, you need to change mysql The user table in the database is

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

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。

. You can modify a piece of data or add a piece of data. But it is best not to modify the data marked in blue above. The modification statement is in the format below

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

4. Finally, exit or \q are Is the method to exit the mysql command line

mysql> \q
Bye

Install Apache

1. The apache installation method is relatively simple

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

2. When visiting the address in the virtual machine, we need to modify the configuration file of Apache /etc/httpd/conf/httpd.conf

Q to find #Servername www.example. com:80 Change to ServerName localhost:80

As shown on the right:

Find #Listen Change to Listen:8080 (an open port in Linux No. 80XX)

As shown in the picture on the right:

3. After the modification is completed, we need to start the httpd service again and check the startup status

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

4. At this time you will You can access your server. Enter localhost or IP address, and an Apache test page powered by centos will appear.

Install PHP

1.php installation command

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

2. Install it directly. After the installation is completed, restart the httpd service again

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

3. After restarting, we will test the PHP related information. We will create a new PHP interface. Test

Create a new test.php page under the apache default page path

/var/www/html and add the code

<?php phpinfo();?>

4. Visit this page and enter localhost/test.php, or

ip:port number/test.php to see the configuration information of the PHP environment. As shown on the right:

Associating php and mysql##　1. Search module

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

　2.Install related modules

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

3. The installation is complete, restart mysqld, restart httpd

Revisit the info.php just now, we found that there is more MySQL related information. As shown on the right:

At this point, the PHP operating environment in Linux has been successfully configured.
