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) Copyright (c) 2000, 2017, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. 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; +-----------+------+-----------------------------------+-------------+-------------+-------------+-------------+-------------+-----------+-------------+---------------+--------------+-----------+------------+-----------------+------------+------------+--------------+------------+-----------------------+------------------+--------------+-----------------+------------------+------------------+----------------+---------------------+--------------------+------------------+------------+--------------+------------------------+----------+------------+-------------+--------------+---------------+-------------+-----------------+----------------------+-----------------------+-----------------------+------------------+ | 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.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
找到 #ServerName www.example.com:80 改为 ServerName localhost:80
如右图所示：
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) Process: 39046 ExecReload=/usr/sbin/httpd $OPTIONS -k graceful (code=exited, status=0/SUCCESS) Main PID: 54573 (httpd) Status: "Processing requests..."

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(); ?>
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
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
