Linux to build PHP running environment

I wrote hello world under Windows before, but it was not enough after all, because the development environment is Linux, what should I do? ~~~Learn, learn and learn again

What I wrote before: I took it from an article in Baidu Library. The original article name is "Installing Apache PHP MySql under Linux and setting up a PHP operating environment"

http://wenku.baidu.com/link?url=7A49L1QOIznRoJVz7fC6qaHGiCHTYacwYTLZJEIT_E7URXqgoftdsZdl0tLfKn2n_Tb8PPZ4LqYsA_F1xn5jBovPIR-aG7qUVmPPx34Ft9a

Installation environment: Red Hat 4.8.2 -16

Required installation software:

• Apache
• PHP
• mysql-server

1 Install Apache

1 Check , delete, install

rpm -qa|grep httpd    //检查是否安装apache
rpm -e 包名 --nodeps    //若有则删除  PS：我没有删除，直接用的服务器原来的。
yum install httpd     //安装，根据提示，输入Y即可安装成功

2 Start and test

sudo systemctl start httpd.service

备注：可以使用/etc/init.d/httpd status/stop/start/restart 分别对应  查看状态/停止/启动/重启
     也可以使用service httpd status/stop/start/restart命令，效果一样的

Enter the server IP in the windows browser and view the page , the following means that apache is installed successfully

2 Install MySql

1 Check, delete and install

rpm -qa|grep -i mysql           //检查是否安装mysql
rpm -e 包名 --nodeps            //若有则删除，另外还有一些库和头文件，我这边都没有，安装后，在他说的路径也没有找到。
yum install mysql mysql-server //安装，根据提示，输入Y即可安装成功。若有提示缺少依赖，直接使用yum install 安装即可，我这儿没遇到

2 Configuration and startup

• Copy file: cp -f /usr/share/mysql/my-medium.cnf /etc/my.cnf ( Just overwrite it)
• Set password: mysql secure installation (Enter Y according to the prompts, enter the password twice, and press Enter. Thanks for using MYSQL! appears to indicate success)
• Remote access:

  mysql -uroot -proot   //-u后面是用户名,-p后面是密码
  use mysql;
  select Host,User from user;
  update user set Host='%' where User='root'; //出现错误不用理睬
  flush privileges;
  select Host,User from user;

• Start mysql:/etc/init.d/mysqld start // service mysqld start has the same effect

Three installations of PHP

1 Installation

yum install php //安装php
//安装组件，支持mysql
yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt

2 Configuration and startup

• The original article wrote a lot of configuration, I don’t know what to do What, I haven’t started according to his changes for the time being: restart httpd mysqld
• After writing the php program or modifying the program, execute the command
service php-fpm reload
• to reload

Four tests

1 Test program

index.php

<?php     phpinfo();
?>

• index1.php
•     $link = mysql_connect("localhost","root","root") or die(mysql_error());     if($link!=false)         {echo "成功连接mysql";}     else         {echo "与本地mysql服务器连接失败";}     mysql_close(); ?>

2 Place it in the root directory of php

,

and execute service php -fpm reload

• You can also configure it yourself: cat /etc/httpd/conf/httpd.conf(DocumentRoot "/var/www/html/")
• You can also modify the file path such as: /var/www/html/test/index.php.
• The corresponding access url is ip/test/index.php
