Centos6.6用yum快速安装LA（N）MP

Posted 2020-11-04

本文主要介绍在CentOS6.6下用yum快速搭建LAMP或LNMP环境

基本流程：

  1.安装apche或nginx

  2.安装mysql

  3.安装php

  4.测试环境

---

流程一：安装apche或nginx

1）关闭SELINUX

修改配置文件，重启服务后永久生效。

sed -i 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config

命令行设置立即生效。

setenforce 0

网易官方源
centos6.x
cd /etc/yum.repos.d/
mv CentOS-Base.repo CentOS-Base.repo.$(date +%F)
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
yum clean all
yum makecache

更多国内知名yum源可参考：http://blog.51cto.com/13707680/2104644

2）安装Apache：

yum -y install httpd

yum -y install httpd-manual mod_ssl mod_perl mod_auth_mysql

/etc/init.d/httpd start 

netstat -tnlp|grep 80

安装nginx：

Centos6系统库中默认是没有nginx的rpm包的，所以我们需要先更新下rpm依赖库

1）使用yum安装nginx，安装nginx库

rpm -Uvh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm

2）使用下面命令安装nginx

yum -y install nginx

[[email protected] ~]# nginx -v 

nginx version: nginx/1.14.0

3）启动nginx

/etc/init.d/nginx start 或 service nginx start

4 ) 防火墙允许通过80端口

vim /etc/sysconfig/iptables

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT 

/etc/init.d/iptables restart

---

流程二：安装mysql

1）安装Mysql，先更新yum源。yum源下载地址，根据自己需要的版本选择相应的源

https://dev.mysql.com/downloads/repo/yum/

2）这里版本是6.x系列的，所以选择linux 6 下载

wget https://repo.mysql.com//mysql57-community-release-el6-11.noarch.rpm

3）安装mysql的yum源

rpm -Uvh mysql57-community-release-el6-11.noarch.rpm  或 yum -y localinstall mysql57-community-release-el6-11.noarch.rpm

4）查看mysql源是否成功

[[email protected] yum.repos.d]# ls /etc/yum.repos.d/|grep mysql

mysql57-community-release-el6-11.noarch.rpm

mysql-community.repo

mysql-community-source.repo

5)安装mysql

yum -y install mysql-community-server

[[email protected] ~]# mysql -V

mysql  Ver 14.14 Distrib 5.7.22, for Linux (x86_64) using  EditLine wrapper

6）开启mysql，并更改默认密码

/etc/init.d/mysqld start 

netstat -tnlp |grep 3306

chkconfig mysqld on

[[email protected] yum.repos.d]# grep 'temporary password' /var/log/mysqld.log 

2018-05-10T22:59:11.434638Z 1 [Note] A temporary password is generated for [email protected]: OScMFRu&j75Q

mysql -uroot -p"OScMFRu&j75Q"

ALTER USER 'root'@'localhost' IDENTIFIED BY 'ywxi123';

mysql -uroot -p"ywxi123"

7）防火墙允许通过3306端口

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

service iptables restart

---

流程三：安装php

1）更新yum源

rpm -Uvh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

2）安装PHP

yum -y install --enablerepo=remi --enablerepo=remi-php56 php php-bcmath php-opcache php-devel php-mbstring php-mcrypt php-mysqlnd php-gd php-xml php-memcache php-redis php-fpm php-mysql php-common php-mssql

3）配置php.ini文件，关闭php信息头

sed 's#expose_php = On#expose_php = Off#g' /etc/php.ini -i

[[email protected] html]# php -v

PHP 5.6.36 (cli) (built: Apr 25 2018 10:11:47)

4）启动php，并开机自启

/etc/init.d/php-fpm start

chkconfig php-fpm on

---

流程四：环境测试

1）LNMP环境测试准备

编辑/etc/nginx/conf.d/default.conf，在所支持的主页面格式中添加php格式的主页，类似如下：

[[email protected] conf.d]# cat default.conf 

server {

    listen       80;

    server_name  localhost;

    #charset koi8-r;

    #access_log  /var/log/nginx/host.access.log  main;

    location / {

        root   /usr/share/nginx/html;

        index index.php index.html index.htm;

    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html

    #

    error_page   500 502 503 504  /50x.html;

    location = /50x.html {

        root   /usr/share/nginx/html;

    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80

    #

    #location ~ \.php$ {

    #    proxy_pass   http://127.0.0.1;

    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

    #

    location ~ \.php$ {

        root           /usr/share/nginx/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;

    }

    # deny access to .htaccess files, if Apache's document root

    # concurs with nginx's one

    #

    #location ~ /\.ht {

    #    deny  all;

    #}

}

[[email protected] html]# cat /usr/share/nginx/html/index.php 

<?php

$conn=mysql_connect('127.0.0.1','root','ywxi123');

if ($conn){

echo "LNMP platform connect to mysql is successful!";

}else{

echo "LNMP platform connect to mysql is failed!";

}

phpinfo();

?>

chown -R nginx.nginx /usr/share/nginx/html/

http://192.168.1.22/index.php 访问到如下页面证明LNMP环境搭建成功

---

2）LAMP环境测试准备

/etc/init.d/nginx stop

/etc/init.d/httpd start

[[email protected] html]# cat /var/www/html/index.php 

<?php

$conn=mysql_connect('127.0.0.1','root','ywxi123');

if ($conn){

echo "LAMP platform connect to mysql is successful!";

}else{

echo "LAMP platform connect to mysql is failed!";

}

phpinfo();

?>

chown -R apache.apache /var/www/html

http://192.168.1.22/index.php 访问到如下页面证明LAMP环境搭建成功
