Centos7 yum安裝 Lnmp以及Lamp

首先配置防火牆 

CentOS 7.0默認使用的是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

或者開啟某端口 
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
成功后重載防火牆firewall-cmd --reload

2.關閉SELINUX

vi /etc/selinux/config 
#SELINUX=enforcing #注釋掉 
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端口號（根據自己需求）

cd /etc/nginx/conf.d/ 
vim default.conf 把listen 80改成listen 81 然后重啟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 
安裝完畢后
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.域名修改  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，安裝后默認為空

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 
#這里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 #輸入下面內容 <?php phpinfo(); ?> :wq! #保存退出

在客戶端瀏覽器輸入服務器IP地址端口號
