Centos7 yum安裝 Lnmp以及Lamp

首先配置防火牆 

CentOS 7.0預設使用的是firewall作為防火牆 

1.關閉firewall：

systemctl stop firewalld.service #停止firewall 
  systemctl disable firewalld.service #禁止firewall開機啟動

或者開啟某埠 
firewall-cmd --permanent --add-port=50000/tcp
用該命令查詢firewall-cmd --permanent --query-port=50000/tcp
如果是yes就是添加成功，如果是no就是沒成功
成功後重載防火牆firewall-cmd --reload

2.關閉SELINUX

vi /etc/selinux/config 
#SELINUX=enforcing #註釋掉 
SELINUX=disabled #增加 
:wq! #保存退出 
setenforce 0 #使配置立即生效

Lnmp安裝

1.安裝nginx

yum install yum-priorities -y 
wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm 
rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm 
yum install nginx

2.啟動nginx

systemctl start nginx.service #啟動nginx 
systemctl stop nginx.service #停止 
systemctl restart nginx.service #重啟 
systemctl enable nginx.service #設置開機啟動

3.更改nginx埠號（根據自己需求）

cd /etc/nginx/conf.d/ 
vim default.conf 
把listen 80改成listen 81 
然後重啟nginx 
systemctl restart nginx.service #重啟nginx

4.訪問http://ip:81即可看到nginx首頁

5.下一步安裝PHP-fpm

yum install php-fpm 
安裝完畢後
systemctl start php-fpm.service #啟動php-fpm 
systemctl enable php-fpm.service #設置開機啟動

6.更改nginx配置文件識別php  vi /etc/nginx/conf.d/default.conf，把之前的#給去掉就可以了，順手改一下fastcgi_param

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; 
    include    fastcgi_params; 
  }

7.訪問test.php

在 /usr/share/nginx/html中新建一個test.php <?php echo 123;?>

訪問http://ip:81/test.php即可看到nginx中的php頁面

8.負載配置

進入 vi /etc/nginx/conf.d/default.conf

upstream site{ 
      server 172.16.170.138; 
      server 172.16.170.139; 
  } 
  server { 
    listen    80; 
    server_name ieccohomo.com; 

    #charset koi8-r; 
    #access_log /var/log/nginx/log/host.access.log main; 

    location / { 
      root  /usr/share/nginx/html; 
      index index.html index.htm; 
      proxy_pass http://ieccohomo.com; 
    }

9.功能變數名稱修改  把上面(ieccohomo.com)site,localhost改為www.a.com

Lamp安裝

1.安裝apache

yum install httpd #根據提示，輸入Y安裝即可成功安裝 
  systemctl start httpd.service #啟動apache 
  systemctl stop httpd.service #停止apache 
  systemctl restart httpd.service #重啟apache 
  systemctl enable httpd.service #設置apache開機啟動

2.安裝mariadb（MySQL）

yum install mariadb mariadb-server #詢問是否要安裝，輸入Y即可自動安裝,直到安裝完成 
  systemctl start mariadb.service #啟動MariaDB 
  systemctl stop mariadb.service #停止MariaDB 
  systemctl restart mariadb.service #重啟MariaDB 
  systemctl enable mariadb.service #設置開機啟動

3.修改mysql密碼，安裝後預設為空

修改mysql密碼：set password for 'root'@'localhost'=password 'root';

mysql授權遠程連接（navicat等）： grant all on *.* to root identified by 'root'; 

4.安裝PHP以及組件，使PHP支持 MariaDB

yum install php php-mysql php-gd libjpeg* php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-bcmath php-mhash 
#這裡選擇以上安裝包進行安裝，根據提示輸入Y回車 
systemctl restart mariadb.service #重啟MariaDB 
systemctl restart httpd.service #重啟apache

5.訪問測試

cd /var/www/html
vi index.php #輸入下麵內容
 <?php
  phpinfo();
?>
:wq! #保存退出

在客戶端瀏覽器輸入伺服器IP地址埠號
