CentOS7系统搭建LAMP及更新PHP版本操作详解

本文实例讲述了centos7系统搭建lamp及更新php版本操作。分享给大家供大家参考，具体如下：

搭建lamp环境 用yum安装

安装apache

1. 安装apache

[root@localhost /]# yum install httpd httpd-devel

2. 启动apache

[root@localhost /]# systemctl start httpd

3. 设置apache开机启动

[root@localhost /]# systemctl enable httpd
created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

4. 查看apache状态

[root@localhost /]# systemctl status httpd
● httpd.service - the apache http server
  loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)

5. 防火墙开启80端口, 依此执行以下命令

[root@localhost /]# firewall-cmd --permanent --zone=public --add-service=http
success
[root@localhost /]# firewall-cmd --permanent --zone=public --add-service=https
success
[root@localhost /]# firewall-cmd --reload
success

6. 查看80端口监听状态

[root@localhost /]# netstat -tulp
active internet connections (only servers)
proto recv-q send-q local address      foreign address     state    pid/program name  
tcp    0   0 0.0.0.0:ssh       0.0.0.0:*        listen   1084/sshd

udp6    0   0 localhost:323      [::]:*               592/chronyd 

7. 查看服务器ip

[root@localhost /]# ip addr
1: lo: <loopback,up,lower_up> mtu 65536 qdisc noqueue state unknown qlen 1
  link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

8. 浏览器登陆查看
   

安装mysql

1. 安装mysql

[root@localhost /]# yum install mariadb mariadb-server mariadb-libs mariadb-devel
[root@localhost /]# rpm -qa |grep maria
mariadb-libs-5.5.52-1.el7.i686
mariadb-5.5.52-1.el7.i686
mariadb-server-5.5.52-1.el7.i686
mariadb-devel-5.5.52-1.el7.i686

2. 开启mysql，并设置开机启动，检查状态

[root@localhost /]# systemctl start mariadb 
[root@localhost /]# systemctl enable mariadb 
created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

3. 查看监听状态

[root@localhost /]# netstat -tulp
active internet connections (only servers)
proto recv-q send-q local address      foreign address     state    pid/program name  
tcp    0   0 0.0.0.0:ssh       0.0.0.0:*        listen   1084/sshd

udp6    0   0 localhost:323      [::]:*               592/chronyd 

4. 数据库安全设置

[root@localhost /]# mysql_secure_installation 

note: running all parts of this script is recommended for all mariadb
   servers in production use! please read each step carefully!

in order to log into mariadb to secure it, we'll need the current
password for the root user. if you've just installed mariadb, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

enter current password for root (enter for none): 
ok, successfully used password, moving on...

setting the root password ensures that nobody can log into the mariadb
root user without the proper authorisation.

set root password? [y/n] y
new password: 
re-enter new password: 
password updated successfully!
reloading privilege tables..
 ... success!


by default, a mariadb installation has an anonymous user, allowing anyone
to log into mariadb without having to have a user account created for
them. this is intended only for testing, and to make the installation
go a bit smoother. you should remove them before moving into a
production environment.

remove anonymous users? [y/n] y
 ... success!

normally, root should only be allowed to connect from 'localhost'. this
ensures that someone cannot guess at the root password from the network.

disallow root login remotely? [y/n] n
 ... skipping.

by default, mariadb comes with a database named 'test' that anyone can
access. this is also intended only for testing, and should be removed
before moving into a production environment.

remove test database and access to it? [y/n] y
 - dropping test database...
 ... success!
 - removing privileges on test database...
 ... success!

reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

reload privilege tables now? [y/n] y
 ... success!

cleaning up...

all done! if you've completed all of the above steps, your mariadb
installation should now be secure.

thanks for using mariadb!

5. 登陆数据库测试

[root@localhost /]# mysql -uroot -p
enter password: 
welcome to the mariadb monitor. commands end with ; or \g.
your mariadb connection id is 11
server version: 5.5.52-mariadb mariadb server

copyright (c) 2000, 2016, oracle, mariadb corporation ab and others.

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

mariadb [(none)]> 

安装php

1. 安装php

[root@localhost /]# yum -y install php
[root@localhost /]# rpm -ql php
/etc/httpd/conf.d/php.conf
/etc/httpd/conf.modules.d/10-php.conf
/usr/lib/httpd/modules/libphp5.so
/usr/share/httpd/icons/php.gif
/var/lib/php/session

2. 将php与mysql关联起来

[root@localhost /]# yum install php-mysql
[root@localhost /]# rpm -ql php-mysql
/etc/php.d/mysql.ini
/etc/php.d/mysqli.ini
/etc/php.d/pdo_mysql.ini
/usr/lib/php/modules/mysql.so
/usr/lib/php/modules/mysqli.so
/usr/lib/php/modules/pdo_mysql.so

3. 安装常用php模块

[root@localhost /]# yum install -y php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel php-bcmath

4. 测试php

[root@localhost /]# cd /var/www/html/
[root@localhost /]# ls
[root@localhost /]# pwd
/var/www/html
[root@localhost /]# vi info.php

<?php
    phpinfo();
?>
~                                            
~                                            
~                                            
~                                            
~                                            
~                                            
~                                            
~                                      
:wq

5. 重启apache

[root@localhost /]# systemctl restart httpd

6. 测试php
   

更新php版本

1. 首先查看是否有老版本

[root@localhost /]# yum list installed | grep php

2. 移除老版本

[root@localhost /]# yum remove php.x86_64 php-cli.x86_64 php-common.x86_64 php-gd.x86_64 php-ldap.x86_64 php-mbstring.x86_64 php-mcrypt.x86_64 php-mysql.x86_64 php-pdo.x86_64

3. 由于linux的yum源不存在php7.x，所以我们要更改yum源：

[root@localhost /]# rpm -uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@localhost /]# rpm -uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

4. 查看yum源中有没有php7.x

[root@localhost /]# yum search php7
