liunx CentOS7 搭建lnmp环境 php nginx mysql

安装一些刚需软件：不懂请自行查询

安装一些需要的软件命令

yum install wget vim net-tools bash* lrzsz tree nmapnc lsof telnet -y

刷新命令

source /usr/share/bash-completion/bash_completion

echo source /usr/share/bash-completion/bash_completion >> ~/.bashrc

继续安装软件

yum -y install iptables-services && systemctl start iptables && systemctl enable iptables

配置yum源 NGINX、MySQL、PHP源

添加Redhat扩展软件源

yum install epel* -y

下载NGINX源安装脚本

wget http://www.atomicorp.com/installers/atomic

sh ./atomic

 MySQL源

rpm -Uvh  http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm

 PHP源

yum install -y \
https://repo.ius.io/ius-release-el7.rpm \
https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

清除旧yum缓存并重新加载 

yum clean all

yum makecache fast

yum repolist

 安装NGINX 

 查看当前仓库是否有NGINX的软件包

yum list | grep nginx

 安装NGINX

yum install nginx -y

启动NGINX并设置开机自启动 

systemctl start nginx && systemctl enable nginx

验证NGINX是否启动成功，出现如下图代码安装成功

如果访问不到，请前去查看防火墙（可以先尝试执行关闭防火墙之后，再去访问是否可以，如果可以说明防火墙没有配置对外开放的80端口。）关于防火墙命令请看此文章

liunx 防火墙（firewalld 和 iptables）_lunx防火墙-CSDN博客

到了这一步说明nginx已经可以访问了，请点击如下链接去安装php版本，更加详细，安装之后再回来继续下面的命令

 centos7 安装php82-CSDN博客

到了这一步，需要将php和nginx关联起来，否则你无法访问php

备份NGINX配置文件（找到你安装的nginx路径）

cp -rp /etc/nginx/nginx.conf{,.bak}

编辑NGINX文件 

vim /etc/nginx/conf.d/default.conf

       location / {
           root   /usr/share/nginx/html;
          index index.php  index.html index.htm;# 添加index.php
      }

     # 去掉注释: 进入视图模式安装ctrl v,向下选中#,按d删除注释符
      location ~ \.php$ {
          root           html;
          fastcgi_pass   127.0.0.1:9000;
          fastcgi_index  index.php;
          fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;# 修改目录
          include        fastcgi_params;
      }

重启NGINX 

systemctl restart nginx.service

配置PHP（查询自己的php.ini文件，切记是你当前使用的版本的php.ini）

cp -rp /etc/opt/remi/php82/php.ini{,.bak}

 编辑php.ini

vim /etc/php.ini

文件末尾添加 

cgi.fix_pathinfo = 1

重启nginx生效 

systemctl restart nginx.service

重启php生效 

systemctl restart php82-php-fpm.service

浏览器访问验证 。出现如下图，代表以上配置全部成功

安装MySQL

yum -y install mysql-community-server --nogpgcheck

验证安装是否成功

mysql -V

出现如下图代表mysql安装成功 

启动mysql 

systemctl start mysqld && systemctl enable mysqld && systemctl daemon-reload

查看当前密码

grep 'temporary password' /var/log/mysqld.log

 出现如下图，密码

执行

mysql_secure_installation

 出现如下图步骤

Enter password for user root:	# 输入:%l/fqdPU*12O
New password: 		# 输入两次新密码

Re-enter new password: 	# 输入两次新密码

Change the password for root ? ((Press y|Y for Yes, any other key for No) : yes	# 是否修改当前的密码

Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : no # 是否使用提供的密码

Remove anonymous users? (Press y|Y for Yes, any other key for No) : yes	# 是否移除匿名用户

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : no	# 不允许root用户远程登录

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : yes	# 删除测试数据库

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : yes	# 是否立刻刷新权限列表

设置MySQL字符串列表

$ vim /etc/my.cnf
[mysqld]
character-set-server=utf8

[client]
default-character-set=utf8

# 重启MySQL
systemctl start mysqld && systemctl enable mysqld && systemctl daemon-reload

# 开启MySQL的root用户远程连接
$ mysql -uroot -p
$ GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Admin@123' WITH GRANT OPTION;
$ FLUSH PRIVILEGES;

全部ok​​​​​​​
