由于电脑重装系统,之前虚拟机中的所有系统都打不开了,不得已又得从0开始安装。我下载的是centos6.5的镜像,在虚拟机中安装完以后,执行了一下yum update,系统升成了6.7的,但是对于lnmp环境的安装时没有影响的,6.5和6.7的安装方法是一样的。
一、安装php5.4
1.配置yum源
6.7和6.5中默认是没有php5.4版本的,所以我们需要先配置一下yum源。
执行命令: rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
-
[root@localhost yum.repos.d]# rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
-
Retrieving http://mirror.webtatic.com/yum/el6/latest.rpm
-
warning: /var/tmp/rpm-tmp.qxPwK1: Header V4 DSA/SHA1 Signature, key ID cf4c4ff9: NOKEY
-
Preparing... ########################################### [100%]
-
1:webtatic-release ########################################### [100%]
2.安装php5.4
执行完以后查看yum search php54w,可以看到php5.4相关的模块。执行命令安装php5.4
-
[root@localhost ~]# yum install php54w
安装完后,执行命令可以看到PHP版本信息
-
[root@localhost ~]# php --version
-
PHP 5.4.45 (cli) (built: Oct 16 2015 11:24:58)
-
Copyright (c) 1997-2014 The PHP Group
-
Zend Engine v2.4.0, Copyright (c) 1998-2014 Zend Technologies
3.安装php-fpm
-
[root@localhost ~]# yum install php-fpm.x86_64
-
Loaded plugins: fastestmirror, refresh-packagekit, security
-
Setting up Install Process
-
Loading mirror speeds from cached hostfile
-
f * base: mirrors.btte.net
-

-

-

-
You could try using --skip-broken to work around the problem
-
You could try running: rpm -Va --nofiles --nodigest
可以看到倒数第三行报了一个冲突,导致安装失败,冲突的原因是php-fpm包依赖5.3版本的php-common,但是我们安装php5.4的时候安装了5.4版本的php-common,所以造成php-common-5.3安装不上,解决这个冲突只要安装依赖php-common-5.4版本的php-fpm就OK
-
[root@localhost ~]# yum search php54w | grep fpm
-

-
Starting php-fpm: [ OK ]
一切顺利!至此php环境就安装完毕,接下来就安装nginx
如果出现“Fatal
error: Call to undefined function mb_strlen()"错误
还需要安装php-mbstring
[root@iZ25fe2mpugZ ~]# yum search php54w| grep mbstring
php54w-mbstring.x86_64 : A module for PHP applications which need multi-byte
[root@iZ25fe2mpugZ ~]# yum install php54w-mbstring.x86_64
如果出现“ Unknown: open(/var/lib/php/session/sess_63u4vit4pii5gelmsq5inf3hd6, O_RDWR) failed: Permission denied”这样的错误,需要将session目录设置777权限。chmod
-R 777 /var/lib/php/session
以此类推,出现“Class ‘DOMDocument‘ not found”,表示xml扩展没有安装
yum search php54w | grep xml
yum install php54w-mbstring.x86_64
二.安装nginx
先看看我们都有哪些版本的Nginx
-
[root@localhost ~]# yum search nginx
-
Loaded plugins: fastestmirror, refresh-packagekit, security
-
Loading mirror speeds from cached hostfile
-
* base: mirrors.btte.net
-
* extras: mirrors.btte.net
-
* updates: mirror.bit.edu.cn
-
* webtatic: uk.repo.webtatic.com
-
================================================================ N/S Matched: nginx ================================================================
-
nginx16.x86_64 : A high performance web server and reverse proxy server
-
nginx18.x86_64 : A high performance web server and reverse proxy server
-
-
Name and summary matches only, use "search all" for everything.
我们选择安装18版本的。
安装的时候发现下载速度奇慢,最后也因为这个安装失败,所以我们现在先替换一下yum源。
-
rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
替换完以后再执行安装。这次下载速度快了很多,安装也很顺利。全部安装完以后,开启nginx服务
-
[root@localhost yum.repos.d]# service nginx start
-
Starting nginx: [ OK ]
关掉防火墙服务
-
[root@localhost yum.repos.d]# service iptables stop
-
iptables: Setting chains to policy ACCEPT: filter [ OK ]
-
iptables: Flushing firewall rules: [ OK ]
-
iptables: Unloading modules: [ OK ]
在浏览器中输入虚拟机的ip,当查看到到下图的时候表示Nginx已经安装成功。
三.修改nginx 配置,使其能够识别php脚本
默认安装完nginx以后,是没办法解析php脚本的,需要修改nginx的配置文件才行。
-
[root@localhost html]# vim /etc/nginx/nginx.conf
1.添加index.php
2.打开FastCGI部分注释(FastCGI、Nginx、php-fpm、php都有哪些关系?稍后文章会详细介绍这一点)
将/scripts改为$document_root
保存退出,重启nginx服务。
进入/usr/share/nginx/html下写一个php脚本,然后测试看能不能打开
-
[root@localhost html]# vim index.php
保存退出,在浏览器中访问该文件,192.168.71.128/index.php(我的虚拟机IP是71.128),如果看到php信息页就表示已经配置成功。接下来就该配置mysql啦。
四.安装MySQL
安装mysql5.5相关的所有的包
-
[root@localhost ~]# yum install mysql55*
-
Loaded plugins: fastestmirror, refresh-packagekit, security
-
Setting up Install Process
-
Loading mirror speeds from cached hostfile
-
* base: mirrors.btte.net
-
* extras: mirrors.btte.net
-
* updates: mirror.bit.edu.cn
-
* webtatic: sp.repo.webtatic.com

-

-

倒数第三行,又出现一个冲突,现在我们先卸载掉mysql-libs-5.1.73-5.el6_7.1.x86_64
-
[root@localhost ~]# yum remove mysql-libs-5.1.73-5.el6_7.1.x86_64
卸载成功后,再次执行安装命令
-
[root@localhost ~]# yum install mysql55*
安装完以后开启mysql服务,查看是否正常
-
[root@localhost ~]# service mysqld start
启动成功后,我们需要给mysql的root用户分配登录密码
-
[root@localhost ~]# mysqladmin -u root password ‘newpassword‘
设置完成后就可以登录mysql控制台了
-
[root@localhost ~]# mysql -u root -p
-
Enter password:
-
Welcome to the MySQL monitor. Commands end with ; or \g.
-

登录没问题,至此MySQL也就安装完毕了,接下来要做的就是让php能够连接上MySQL
五、安装php-mysql扩展
1.安装扩展
查看是否有安装php-mysql扩展
-
[root@localhost ~]# php -i | grep mysql
命令结果返回空,说明没有安装,那么现在我们就需要安装这些扩展。搜索yum源,找到合适的扩展包
-
[root@localhost ~]# yum search all php-mysql
-
Loaded plugins: fastestmirror, refresh-packagekit, security
-
Loading mirror speeds from cached hostfile
-
* base: mirrors.btte.net
-
* extras: mirrors.btte.net
-
* updates: mirror.bit.edu.cn
-
* webtatic: us-east.repo.webtatic.com
-
================================================================ Matched: php-mysql ================================================================
-
php-mysql.x86_64 : A module for PHP applications that use MySQL databases
-
php54w-mysqlnd.x86_64 : A module for PHP applications that use MySQL databases
-
php55w-mysqlnd.x86_64 : A module for PHP applications that use MySQL databases
-
php56w-mysqlnd.x86_64 : A module for PHP applications that use MySQL databases
-
php70w-mysqlnd.x86_64 : A module for PHP applications that use MySQL databases
安装php54w-mysqlnd,因为我们php是php5.4版本的
-
[root@localhost ~]# yum install -y php54w-mysqlnd.x86_64
安装完以后重启php-fpm,再次浏览192.168.71.128/index.php就可以看到mysql扩展啦。
下面就写个简单脚本测试一下php连接mysql的情况。
2.测试扩展
首先登录mysql控制台,在test中创建一张表,并写入几条数据
-
mysql> create table person(
-
-> id int not null primary key auto_increment,
-
-> name char(5) not null
-
-> )engine=innodb default charset=utf8;
-
mysql> insert into person (name) values (‘zhangsan‘),(‘lisi‘),(‘wangwu‘);
测试表准备好以后,开始写测试脚本
-
[root@localhost ~]# cd /usr/share/nginx/html/
-
[root@localhost html]# vim mysql.php
-
<?php
-
try{
-
$pdo = new PDO(‘mysql:host=localhost;dbname=test‘,‘root‘,‘root‘);
-
$res = $pdo->query(‘select * from person‘);
-
foreach ($res as $row) {
-
echo ‘<pre>‘;print_r($row);
-
}
-
} catch (PDOException $e) {
-
print "Error:".$e->getMessage()."<br/>";
-
die;
-
}
访问脚本192.168.71.128/mysql.php,如果看到下面内容,说明php-mysql扩展已经没有问题。
六、将lnmp加入开机启动项
经过上面五部的操作,我们的lnmp环境就已经成功搭建完成了,为了后续的使用,我们现在把php-fpm/nginx/mysql都加入到开机启动项中。
-
[root@localhost html]# chkconfig php-fpm on
-
[root@localhost html]# chkconfig nginx on
-
[root@localhost html]# chkconfig mysqld on
注:如果重启机器后发现nginx访问不了了,请检查一下防火墙是不是打开了,因为centos默认防火墙是开机启动的。
至此,lnmp环境就彻底的搭建完成啦,尽情的享受coding吧~centos6.7、centos6.5下yum方式搭建lnmp环境,php5.4/mysql5.5
