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 Use the yum command to install.
# 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:
It is best to install mysql and apache first, because when configuring php, you need to configure and test related mysql and apache
First download mysql-sever file, because the blogger’s Linux environment is the CentOS version, and there seems to be 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 complete, 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. Enter the mysql command line
[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) Copyright (c) 2000, 2017, Oracle and/or its affiliates.

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. Because the blogger uses The local navicat software is used to connect to mysql under Linux, so if you want to access it locally, you need to change the user table in the mysql database
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 changedmysql>
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;+-----------+------+-----------------------------------+-------------+-------------+-------------+-------------+-------------+-----------+-------------+---------------+--------------+-----------+------------+-----------------+------------+------------+--------------+------------+-----------------------+------------------+--------------+-----------------+------------------+------------------+----------------+---------------------+--------------------+------------------+------------+--------------+------------------------+----------+------------+-------------+--------------+---------------+-------------+-----------------+----------------------+-----------------------+-----------------------+------------------+ | Host | User | Password | Select_priv | Insert_priv | Update_priv | Delete_priv | Create_priv | Drop_priv | Reload_priv | Shutdown_priv | Process_priv | File_priv | Grant_priv | References_priv | Index_priv | Alter_priv | Show_db_priv | Super_priv | Create_tmp_table_priv | Lock_tables_priv | Execute_priv | Repl_slave_priv | Repl_client_priv | Create_view_priv | Show_view_priv | Create_routine_priv | Alter_routine_priv | Create_user_priv | Event_priv | Trigger_priv | Create_tablespace_priv | ssl_type | ssl_cipher | x509_issuer | x509_subject | max_questions | max_updates | max_connections | max_user_connections | plugin | authentication_string | password_expired | +-----------+------+-----------------------------------+-------------+-------------+-------------+-------------+-------------+-----------+-------------+---------------+--------------+-----------+------------+-----------------+------------+------------+--------------+------------+-----------------------+------------------+--------------+-----------------+------------------+------------------+----------------+---------------------+--------------------+------------------+------------+--------------+------------------------+----------+------------+-------------+--------------+---------------+-------------+-----------------+----------------------+-----------------------+-----------------------+------------------+| % | root | *3ce8dad2446975d8b0c771bd7e48d15b | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | | | | | 0 | 0 | 0 | 0 | mysql_native_password | | N || localhost | root | *3ce8dad2446975d8b0c771bd7e48d15b | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | | | | | 0 | 0 | 0 | 0 | mysql_native_password | | N | | 127.0.0.1 | root | *3ce8dad2446975d8b0c771bd7e48d15b | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | | | | | 0 | 0 | 0 | 0 | mysql_native_password | | N | | ::1 | root | *3ce8dad2446975d8b0c771bd7e48d15b | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | Y | | | | | 0 | 0 | 0 | 0 | mysql_native_password | | N || tele-1 | | | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | N | | | | | 0 | 0 | 0 | 0 | mysql_native_password | NULL | N | +-----------+------+-----------------------------------+-------------+-------------+-------------+-------------+-------------+-----------+-------------+---------------+--------------+-----------+------------+-----------------+------------+------------+--------------+------------+-----------------------+------------------+--------------+-----------------+------------------+------------------+----------------+---------------------+--------------------+------------------+------------+--------------+------------------------+----------+------------+-------------+--------------+---------------+-------------+-----------------+----------------------+-----------------------+-----------------------+------------------+ 5 rows in set (0.00 sec)mysql>
3 The blogger's table is the modified table. If you want to access remotely, you need the data marked in red above. Host refers to the IP address that can access this database, and % means that all requests can be connected. .
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 the methods to exit the mysql command line
mysql> \q Bye
1. The apache installation method is relatively simple
[root@tele-2 ~]# yum install httpd
2. External network access virtual For the address in the machine, we need to modify the apache configuration file /etc/httpd/conf/httpd.conf
#ServerName www.example.com:80 Change to ServerName localhost:80
As shown on the right Shown:
## Find
#Listen is changed to Listen:8080 (Open port number 80XX in Linux)
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

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.
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 startRedirecting 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();?>
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：
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
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
/var/lib/mysql/ ：/usr/share/mysql（mysql.server） /usr/bin（mysqladmin mysqldump） my.cnf: /etc/my.cnf ：/etc/rc.d/init.d/mysql
：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
service httpd start
service httpd stop
运行状态：service httpd status
3.php
php默认页面路径：/var/www/html
