Centos7.4之安装lamp-php7.0

一. 环境准备
桥接模式
能访问外网

	
	#ping www.baidu.com
	ping得通则能到外网

关闭防火墙

	#systemctl disable firewalld  //禁用防火墙
	#systemctl stop firewalld	//关闭防火墙

关闭seLinux

	#vim /etc/selinux/config
	改为 SELINUX=disabled

配置yum源

	# cd /etc/yum.repos.d/
	# mkdir repo_bak   	//创建备份源文件夹
	# mv *.repo repo_bak/	//将源文件都放到备份文件夹
	
	# wget http://mirrors.aliyun.com/repo/Centos-7.repo	  //配置阿里源
	# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo  //配置网易源
	# ls		//列出/etc/yum.repos.d/目录下的文件 
	Centos-7.repo  CentOS-Base-163.repo  repo.bak
	
	# yum clean all 		//清除系统所有yum缓存
	# yum makecache	 	//生成yum缓存
	
	# yum list | grep epel-release 	 //查看epel源列表
	# yum install -y epel-release	 //安装epel源
	# ls 		//epel源安装成功，比原来多了一个epel.repo和epel-testing.repo文件
	Centos-7.repo  CentOS-Base-163.repo  epel.repo  epel-testing.repo  repo.bak
	
	# wget -O /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo 		//下载阿里源的epel源
	# ls
	CentOS7-Base-163.repo  Centos-7.repo  epel-7.repo  epel.repo  epel-testing.repo  repo_bak
	
	# yum clean all		//再次清除系统yum缓存
	# yum makecache		//重新生成新的yum缓存
	
	# yum repolist enabled		//查看系统可用的yum源
	# yum repolist all			//查看所有yum源

删除旧版本

	# yum -y remove php

二. Apache

安装Apache

	# yum install httpd

配置Apache

	# vim /etc/httpd/conf/httpd.conf
	//搜索
	# AddType application/x-gzip .gz .tgz
	//然后在后面添加
	# AddType application/x-httpd-php .php
	//搜索
	# IfModule dir_module
	//在DirectoryIndex下面添加   index.php
	//修改#ServerName www.example.com:80
	# ServerName localhost:80
	 
	修改默认Web站点目录
	 
	找到： DocumentRoot "/var/www/html"
	修改为： DocumentRoot "/var/www"
	 
	找到：<Directory "/var/www/html"> 
	修改为：<Directory "/var/www">

启动Apache服务

	# systemctl start httpd

查看httpd状态

	systemctl status httpd

三. PHP 7.0.7

下载好对应版本的centos的PHP源码包

	php-7.0.7.tar.gz

解压源码包

	# tar zxvf php-7.0.7.tar.gz

进入解压包编译安装php所需要的依赖包

	# yum install -y gcc gcc-c++ make automake autoconf gd file bison patch mlocate flex diffutils zlib zlib-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel libcurl libcurl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers openldap-devellibxslt-devel kernel-devel libtool-libs readline-devel gettext-devel libcap-devel php-mcrypt libmcrypt libmcrypt-devel recode-devel gmp-devel icu  libxslt libxslt-devel php-devel
	# yum -y install libxslt-devel*
	# yum -y install perl* 
	# yum -y install httpd-devel
	# find / -name apxs 		//得到的路径是:/usr/bin/apxs 编译参数的时候用到，是配置Apache支持PHP的关键参数

编译参数

编译并安装

	# make && make install

安装完查看PHP版本

	# /usr/local/php/bin/php -v

编辑 /etc/profil 添加环境变量

	# vim /etc/profil
	添加进去
	PATH=$PATH:/usr/local/php/bin
	export PATH

更新环境变量

	# source /etc/profile

查看环境变量

	# echo $PATH

查看PHP版本

	# php -v

配置PHP配置文件php-fpm

	# cp php.ini-production /etc/php.ini
	
	# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
	
	# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
	
	# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
	
	# chmod +x /etc/init.d/php-fpm
	
	# vim /usr/local/php/etc/php-fpm.conf
	# 配置错误日志:
 	# 
	# error_log = /usr/local/php/var/php-fpm.log
	# 
	# 配置pid文件:    
	# 
	#  pid = /usr/local/php/var/run/php-fpm.pid
	#  
	# 保存退出
	
	# cd /usr/local/src/php-7.2.4
 
	# cp ./sapi/fpm/php-fpm.service 到 /usr/lib/systemd/system/下

启动php-fpm

	配置开机启动php-fpm:
	# systemctl enable php-fpm
	启动php-fpm
	# systemctl start php-fpm
	查看状态
	# systemctl status php-fpm
	● php-fpm.service – The PHP FastCGI Process Manager
	Loaded: error (Reason: Invalid argument)
	Active: inactive (dead)
	 
	Dec 13 14:37:27 localhost.localdomain systemd[1]: [/usr/lib/systemd/system/php-fpm.service:7] Not an absolute path, ignoring: ${prefix}/va…fpm.pid

测试php-fpm的配置

	#测试php-fpm配置
	/usr/local/php/sbin/php-fpm -t
	/usr/local/php/sbin/php-fpm -c /usr/local/php/etc/php.ini -y /usr/local/php/etc/php-fpm.conf -t
	
	#启动php-fpm
	/usr/local/php/sbin/php-fpm
	/usr/local/php/sbin/php-fpm -c /usr/local/php/etc/php.ini -y /usr/local/php/etc/php-fpm.conf

	#关闭php-fpm
	kill -INT `cat /usr/local/php/var/run/php-fpm.pid`
	
	#重启php-fpm
	kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`

解决办法

	# vim /usr/lib/systemd/system/php-fpm.service
	 
	将其中的${prefix}和${exec_prefix}改成/usr/local/php然后保存
	 
	//重新启动系统
	# reboot

重启Apache和php-fpm

	# systcl restart httpd
	# systcl restart php-fpm

安装对应的xdebug

	#复制phpinfo.php整个网页内容,粘贴到https://xdebug.org/wizard.php 确定Xdebug版本

在这里插入图片描述
根据提示文档进行操作安装

yum安装PHPMyAdmin

	# yum install phpmyadmin

修改配置文件

	# vi /etc/httpd/conf.d/phpMyAdmin.conf
	
	<Directory /usr/share/phpMyAdmin/>
	   AddDefaultCharset UTF-8
	
	   <IfModule mod_authz_core.c>
	     # Apache 2.4
	     <RequireAny>
	      # Require ip 127.0.0.1  #注释掉
	      # Require ip ::1   #注释掉
	      Require all granted   #新添加
	     </RequireAny>
	 </IfModule>
	 <IfModule !mod_authz_core.c>
	     # Apache 2.2
	     Order Deny,Allow
	     Deny from All
	     Allow from 127.0.0.1
	     Allow from ::1
	   </IfModule>
	</Directory>
	
	<Directory /usr/share/phpMyAdmin/setup/>
	   <IfModule mod_authz_core.c>
	     # Apache 2.4
	     <RequireAny>
	      #Require ip 127.0.0.1  #注释掉
	      #Require ip ::1   #注释掉
	      Require all granted   #新添加
	     </RequireAny>
	   </IfModule>
	   <IfModule !mod_authz_core.c>
	     # Apache 2.2
	     Order Deny,Allow
	     Deny from All
	     Allow from 127.0.0.1
	     Allow from ::1
	   </IfModule>
	</Directory>

修改phpmyadmin配置文件

	# vi /etc/phpMyAdmin/config.inc.php
	//修改如下内容
	# $cfg['Servers'][$i]['host'] = '127.0.0.1';
	# $cfg['Servers'][$i]['user'] = 'root';
	# $cfg['Servers'][$i]['password'] = '123456';

重启Apache

	# systemctl restart httpd

安装完MySQL后测试

	# 浏览器地址栏输入: 服务器ip/phpMyAdmin

四. 安装MySQL 5.7

安装源

	# rpm -Uvh https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

yum安装MySQL

	# yum install mysql-community-server

启动MySQL

	# systemctl start mysqld
	# systemctl enable mysqld  //开机自启

在更改root默认密码前，可以根据需要，关闭密码策略。如果没有关闭密码策略，则新密码要求是大小写字母+数字+字符的组合。

	# vim /etc/my.cnf
	[mysqld]
	validate_password = off
	 
	//重启，使修改后的密码策略生效
	# systemctl restart mysqld

修改MySQL的root默认密码

	//查看默认密码
	# grep 'temporary password' /var/log/mysqld.log 
	 
	//默认密码是： )U4FB:Kw!evF
	# 2018-12-18  A temporary password is generated for root@localhost: )U4FB:Kw!evF

	运行安全设置向导，并修改默认密码
	 
	mysql_secure_installation
	 
	//输入root默认密码
	Enter password for user root: ***
	//设置新密码
	New password:***
	Re-enter new password: ***
	//是否更改root密码
	Change the password for root ? ((Press y|Y for Yes, any other key for No) ://直接回车，表示No
	//是否删除匿名用户
	Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
	//禁止root远程登录
	Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
	//删除test数据库
	Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
	//重新加载权限表
	Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y

	//也可以使用mysql直接更改root密码
	mysql -uroot -p
	ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码'; 
	exit;

	//为安全root仅限本地登录，根据需要可以新建一个有管理员权限的远程用户
	mysql -uroot -p
	
	GRANT ALL PRIVILEGES ON *.* TO '用户名'@'%' IDENTIFIED BY '登录密码' WITH GRANT OPTION;
	 
	FLUSH PRIVILEGES;
	 
	exit;

安装完成
