用yum快速搭建LAMP平台

实验环境:

[root@nmserver-7 html]# cat  /etc/redhat-release 
CentOS release 7.3.1611 (AltArch) 

[root@nmserver–7 html]

# uname -a Linux nmserver-7.test.com 3.10.0-514.el7.centos.plus.i686 #1 SMP Wed Jan 25 12:55:04 UTC 2017 i686 i686 i386 GNU/Linux

1、安装apache

  1.1 安装apache

[root@nmserver-7 ~]# yum install httpd httpd-devel

  1.2 启动apache服务

[root@nmserver-7 ~]# systemctl start  httpd

  1.3 设置httpd服务开机启动

[root@nmserver-7 ~]# systemctl enable  httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

  1.4 查看服务状态

复制代码
[root@nmserver-7 ~]# systemctl status httpd
● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: active (running) since 五 2017-07-21 17:21:37 CST; 6min ago Docs: man:httpd(8) man:apachectl(8) Main PID: 2449 (httpd) Status: "Total requests: 11; Current requests/sec: 0; Current traffic: 0 B/sec" CGroup: /system.slice/httpd.service ├─2449 /usr/sbin/httpd -DFOREGROUND ├─2450 /usr/sbin/httpd -DFOREGROUND ├─2451 /usr/sbin/httpd -DFOREGROUND ├─2452 /usr/sbin/httpd -DFOREGROUND ├─2453 /usr/sbin/httpd -DFOREGROUND ├─2454 /usr/sbin/httpd -DFOREGROUND ├─2493 /usr/sbin/httpd -DFOREGROUND ├─2494 /usr/sbin/httpd -DFOREGROUND └─2495 /usr/sbin/httpd -DFOREGROUND 7月 21 17:21:35 nmserver-7.test.com systemd[1]: Starting The Apache HTTP Server... 7月 21 17:21:36 nmserver-7.test.com httpd[2449]: AH00558: httpd: Could not reliably determine the server's fully q...ssage 7月 21 17:21:37 nmserver-7.test.com systemd[1]: Started The Apache HTTP Server.

  1.5 防火墙设置开启80端口

[root@nmserver-7 ~]# firewall-cmd --permanent --zone=public  --add-service=http 
success

[root@nmserver–7 ~]

# firewall-cmd –permanent –zone=public –add-service=https

success

[root@nmserver–7 ~]


# firewall-cmd –reload

success

  1.6确认80端口监听中

复制代码
[root@nmserver-7 ~]# 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 tcp 0 0 localhost:smtp 0.0.0.0:* LISTEN 1486/master tcp6 0 0 [::]:ssh [::]:* LISTEN 1084/sshd tcp6 0 0 localhost:smtp [::]:* LISTEN 1486/master tcp6 0 0 [::]:http [::]:* LISTEN 2449/httpd udp 0 0 localhost:323 0.0.0.0:* 592/chronyd udp6 0 0 localhost:323 [::]:* 592/chronyd
复制代码

  1.8 查服务器IP

复制代码
[root@nmserver-7 ~]# ip addr

  2.3 数据库安全设置

复制代码
[root@nmserver-7 ~]# 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

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... ...

3、安装PHP

  3.1 安装php

[root@nmserver-7 ~]# yum -y install php
[root@nmserver-7 ~]# 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

  3.2 将php与mysql关联起来

复制代码
[root@nmserver-7 ~]# yum install php-mysql

[root@nmserver–7 ~]

# rpm -ql php-mysql

/etc/php.d/mysql.ini /etc/php.d/mysqli.ini

/etc/php.d/pdo_mysql.ini

/usr/lib/php/modules/mysqli.so

/usr/lib/php/modules/pdo_mysql.so

复制代码

  3.3 安装常用PHP模块

[root@nmserver-7 ~]# 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

  3.4 测试PHP

复制代码
[root@nmserver-7 ~]# cd  /var/www/html/
[root@nmserver-7 html]# ls
[root@nmserver-7 html]# pwd
/var/www/html
[root@nmserver-7 html]# vi info.php

<?php
        phpinfo();
?>
~                                                                                        
~                                                                                        
~                                                                                        
~                                                                                        
~                                                                                        
~                                                                                        
~                                                                                        
~        :wq
复制代码

  3.5重启apache服务器

[root@nmserver-7 html]# systemctl restart httpd

  3.6测试PHP

  在自己电脑浏览器输入 192.168.8.9/info.php,你可以看到已经安装的模块;

至此,CentOS7下LAMP环境搭建好了!下一步可以安装zabbix了!

树莓派 之路(1)重置环境

开妈之前,提醒一定一定要不定期备份整张SD卡,不然出事,真的就是重头再来 。

首先重新下载了新版的树莓派系统
下载网址:http://shumeipai.nxez.com/download#os
版本:http://director.downloads.raspberrypi.org/raspbian/images/raspbian-2018-11-15/2018-11-13-raspbian-stretch.zip

在windows下win32diskImager把 解压的IMG写到U盘与TF卡,

用读卡器修改TF BOOT目录下的CMDLINE.TXT文件

最后加上一句 program_usb_boot_mode=1

用TF启动树莓派,上电启动,不用管,过了60秒,直接关电,

拨掉TF卡,再插上优盘,系统就能从U盘启动了。
