内容图文
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 Technologies3.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 * extras: mirrors.btte.net * updates: mirror.bit.edu.cn * webtatic: sp.repo.webtatic.com Resolving Dependencies --> Running transaction check ---> Package php-fpm.x86_64 0:5.3.3-46.el6_7.1 will be installed --> Processing Dependency: php-common(x86-64) = 5.3.3-46.el6_7.1 for package: php-fpm-5.3.3-46.el6_7.1.x86_64 --> Running transaction check ---> Package php-common.x86_64 0:5.3.3-46.el6_7.1 will be installed --> Processing Conflict: php54w-common-5.4.45-2.w6.x86_64 conflicts php-common < 5.4.0 --> Finished Dependency Resolution Error: php54w-common conflicts with php-common-5.3.3-46.el6_7.1.x86_64 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 php54w-fpm.x86_64 : PHP FastCGI Process Manager [root@localhost ~]# yum install php54w-fpm.x86_64 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 Resolving Dependencies --> Running transaction check ---> Package php54w-fpm.x86_64 0:5.4.45-2.w6 will be installed --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================================================================== Package Arch Version Repository Size ==================================================================================================================================================== Installing: php54w-fpm x86_64 5.4.45-2.w6 webtatic 1.3 M Transaction Summary ==================================================================================================================================================== Install 1 Package(s) Total download size: 1.3 M Installed size: 3.8 M Is this ok [y/N]: y Downloading Packages: php54w-fpm-5.4.45-2.w6.x86_64.rpm | 1.3 MB 00:13 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : php54w-fpm-5.4.45-2.w6.x86_64 1/1 Verifying : php54w-fpm-5.4.45-2.w6.x86_64 1/1 Installed: php54w-fpm.x86_64 0:5.4.45-2.w6 Complete!
测试php-fpm服务是否正常
[root@localhost ~]# service php-fpm start 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
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.conf1.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
<?php phpinfo();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 Resolving Dependencies --> Running transaction check ---> Package mysql55w.x86_64 0:5.5.49-1.w6 will be installed ---> Package mysql55w-bench.x86_64 0:5.5.49-1.w6 will be installed --> Processing Dependency: perl(GD) for package: mysql55w-bench-5.5.49-1.w6.x86_64 --> Processing Dependency: perl(DBI) for package: mysql55w-bench-5.5.49-1.w6.x86_64 ---> Package mysql55w-devel.x86_64 0:5.5.49-1.w6 will be installed --> Processing Dependency: openssl-devel for package: mysql55w-devel-5.5.49-1.w6.x86_64 ---> Package mysql55w-embedded.x86_64 0:5.5.49-1.w6 will be installed ---> Package mysql55w-embedded-devel.x86_64 0:5.5.49-1.w6 will be installed ---> Package mysql55w-libs.x86_64 0:5.5.49-1.w6 will be installed --> Processing Dependency: libmysqlclient16 for package: mysql55w-libs-5.5.49-1.w6.x86_64 ---> Package mysql55w-server.x86_64 0:5.5.49-1.w6 will be installed --> Processing Dependency: perl-DBD-MySQL for package: mysql55w-server-5.5.49-1.w6.x86_64 ---> Package mysql55w-test.x86_64 0:5.5.49-1.w6 will be installed --> Processing Dependency: perl(Time::HiRes) for package: mysql55w-test-5.5.49-1.w6.x86_64 --> Running transaction check ---> Package libmysqlclient16.x86_64 0:5.1.69-1.w6 will be installed ---> Package openssl-devel.x86_64 0:1.0.1e-42.el6_7.4 will be installed --> Processing Dependency: zlib-devel for package: openssl-devel-1.0.1e-42.el6_7.4.x86_64 --> Processing Dependency: krb5-devel for package: openssl-devel-1.0.1e-42.el6_7.4.x86_64 ---> Package perl-DBD-MySQL.x86_64 0:4.013-3.el6 will be installed ---> Package perl-DBI.x86_64 0:1.609-4.el6 will be installed ---> Package perl-GD.x86_64 0:2.44-3.el6 will be installed ---> Package perl-Time-HiRes.x86_64 4:1.9721-141.el6_7.1 will be installed --> Running transaction check ---> Package krb5-devel.x86_64 0:1.10.3-42z1.el6_7 will be installed --> Processing Dependency: libselinux-devel for package: krb5-devel-1.10.3-42z1.el6_7.x86_64 --> Processing Dependency: libcom_err-devel for package: krb5-devel-1.10.3-42z1.el6_7.x86_64 --> Processing Dependency: keyutils-libs-devel for package: krb5-devel-1.10.3-42z1.el6_7.x86_64 ---> Package zlib-devel.x86_64 0:1.2.3-29.el6 will be installed --> Running transaction check ---> Package keyutils-libs-devel.x86_64 0:1.4-5.el6 will be installed ---> Package libcom_err-devel.x86_64 0:1.41.12-22.el6 will be installed ---> Package libselinux-devel.x86_64 0:2.0.94-5.8.el6 will be installed --> Processing Dependency: libsepol-devel >= 2.0.32-1 for package: libselinux-devel-2.0.94-5.8.el6.x86_64 --> Processing Dependency: pkgconfig(libsepol) for package: libselinux-devel-2.0.94-5.8.el6.x86_64 --> Running transaction check ---> Package libsepol-devel.x86_64 0:2.0.41-4.el6 will be installed --> Processing Conflict: mysql55w-libs-5.5.49-1.w6.x86_64 conflicts mysql-libs < 5.5 --> Finished Dependency Resolution Error: mysql55w-libs conflicts with mysql-libs-5.1.73-5.el6_7.1.x86_64 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest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. Your MySQL connection id is 2 Server version: 5.5.49 MySQL Community Server (GPL) Copyright (c) 2000, 2016, 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>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~
