CentOS6搭建LNMP环境

发表于

LNMP代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构。
Linux是一类Unix计算机操作系统的统称，是目前最流行的免费操作系统。代表版本有：debian、centos、ubuntu、fedora、gentoo等。
Nginx是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP代理服务器。
Mysql是一个小型关系型数据库管理系统。 PHP是一种在服务器端执行的嵌入HTML文档的脚本语言。
这四种软件均为免费开源软件，组合到一起，成为一个免费、高效、扩展性强的网站服务系统。

selinux可能会致使编译安装失败，我们先禁用它。永久禁用，需要重启生效

1
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

临时禁用，不需要重启

1
setenforce 0

添加防火墙规则允许80端口

1
iptables -I INPUT -p tcp --dport 80 -j ACCEPT

说明：
pcre`opensslzlib是安装nginx时需要的cmake是安装MySQL`时需要的

cd /usr/local/mysql/
scripts/mysql_install_db --user=mysql --datadir=/data/mysql
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
cp support-files/mysql.server /etc/init.d/mysqld

添加启动目录

1
vim /etc/profile

按G移动光标到最后一行o插入以下两行

1
2
PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
export PATH

更新配置文件

1
source /etc/profile

设置开机启动并启动

1
2
chkconfig mysqld on
service mysqld start

登陆测试，默认是没有密码,直接回车就可进入

1
mysql -uroot -p

设置mysql密码

1
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('password');

查看用户

1
select user,host from mysql.user;

删除不必要的用户

1
2
3
4
drop user ""@localhost;
drop user ""@c65mini.localdomain;
drop user root@c65mini.localdomain;
drop user root@'::1';

赋予账号远程访问的权限

1
2
3
GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1' IDENTIFIED BY '你的密码' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '你的密码' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'c65mini.localdomain' IDENTIFIED BY '你的密码' WITH GRANT OPTION;

针对数据库创建一个全部权限的用户

1
grant all onwordpress.* to 'admin'@'localhost' identified by '123456'; UPDATE user SET password=PASSWORD('123456') WHERE user='root';

其它一些信息查询： 检查mysql版本

1
mysql -uroot -p"密码" -e "select version();"

安装php

cp /usr/local/src/php-5.6.30/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.d/php-fpm
service php-fpm start
chkconfig php-fpm on

查看PHP进程是否启动:

1
ps aux |grep php-fpm

看看是不是有很多个进程（大概20多个）。
进入nginx目录，准备安装nginx
