搭建 LNMP 环境

April 2, 2018 • Read: 4478 • 环境搭建

阿里云一台服务器出现问题!

我估计是一键安装包环境的原因,所以打算重新搭建下环境!

首先,当然是先做好快照!安全第一!

对系统盘做更换系统操作,装上纯净版的centos。

装好后,进入系统

一、挂载数据盘

df -h

只有系统盘了,挂载上原来的数据盘

fdisk -l

2.jpg

看到数据盘了/dev/vdb1

挂载上这个数据盘,

mkdir /data0

mount /dev/vdb1 /data0

3.jpg
然后写入分区:

echo '/dev/vdb1  /data0 ext4    defaults    0  0' >> /etc/fstab

不写入分区表,重启后又要挂载的。

怎么知道分区类型是ext4,用这个命令:

df -hT

好的成功了!

二、安装nginx

首先更新系统软件

yum update

安装nginx

1.安装nginx源

yum localinstall http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2.安装nginx

# yum install nginx

3.启动nginx

 service nginx start
Redirecting to /bin/systemctl start  nginx.service

4.访问http://你的ip/

如果成功安装会出来nginx默认的欢迎界面

三、安装MySQL5.7.*

1.安装mysql源

yum localinstall  http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm

2.安装mysql

yum install mysql-community-server

3.安装mysql的开发包,以后会有用

yum install mysql-community-devel

4.启动mysql

service mysqld start
Redirecting to /bin/systemctl start  mysqld.service

5.查看mysql启动状态

service mysqld status

出现pid

证明启动成功

6.获取mysql默认生成的密码

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

5.jpg
选中的就是密码。

7.换成自己的密码

mysql -uroot -p
Enter password:输入上页的密码,进入mysql
  1. 更换密码

    mysql>  ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPasdfs4!';
    

这个密码一定要足够复杂,不然会不让你改,提示密码不合法;

9.退出mysql并试用下新密码

mysql> quit;

mysql -uroot -p

确认密码正确

四、编译安装php7.0.0

1.下载php7源码包

cd /root & wget -O php7.tar.gz http://cn2.php.net/get/php-7.0.1.tar.gz/from/this/mirror

2.解压源码包

tar -xvf php7.tar.gz

3.进入目录

cd php-7.0.1

4.安装php依赖包 

yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel

5.编译配置,这里如果上一步的某些依赖包没有安装好,就会遇到很多configure error,我们一一解决,安装上相关软件开发包就可以

复制代码

./configure \
--prefix=/usr/local/php \
--with-config-file-path=/etc \

configure error:

configure: error: xml2-config not found. Please check your libxml2 installation

解决:

<span style="color: #ff0000"># yum install libxml2 libxml2-devel</span>
 
configure: error: Cannot find OpenSSL's <evp.h>

解决:

1
<span style="color: #ff0000"># yum install libjpeg libjpeg-devel</span>
6.If configure fails try --with-webp-dir=<DIR>

checking for jpeg_read_header in -ljpeg... yes

6.编译与安装

make && make install

这里要make好久,要耐心一下

7.添加 PHP 命令到环境变量

 vim /etc/profile

在末尾加入

PATH=$PATH:/usr/local/php/bin

export PATH

要使改动立即生效执行

 source /etc/profile

查看环境变量

`echo $PATH`

查看php版本

php -v

8.配置php-fpm

# cp php.ini-production /etc/php.ini
# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
# chmod +x /etc/init.d/php-fpm

9.启动php-fpm

# /etc/init.d/php-fpm start

五、配置nginx虚拟机,绑定域名

# vim /etc/nginx/conf.d/php7.aaa.com.conf

这里可以把php7.aaa.com.conf改成自己的域名
把下面的内容复制到php7.aaa.com.conf里

复制代码

server{
    listen 80;
    server_name  php7.aaa.com;
    root /var/www/html/php7.aaa.com; # 该项要修改为你准备存放相关网页的路径
    location / {
        index  index.php index.html index.htm;
         #如果请求既不是一个文件,也不是一个目录,则执行一下重写规则
         if (!-e $request_filename)
         {
            #地址作为将参数rewrite到index.php上。
            rewrite ^/(.*)$ /index.php/$1;
            #若是子目录则使用下面这句,将subdir改成目录名称即可。
            #rewrite ^/subdir/(.*)$ /subdir/index.php/$1;
         }
    }
    #proxy the php scripts to php-fpm
    location ~ \.php {
            include fastcgi_params;
            ##pathinfo支持start
            #定义变量 $path_info ,用于存放pathinfo信息
            set $path_info "";
            #定义变量 $real_script_name,用于存放真实地址
            set $real_script_name $fastcgi_script_name;
            #如果地址与引号内的正则表达式匹配
            if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
                    #将文件地址赋值给变量 $real_script_name
                    set $real_script_name $1;
                    #将文件地址后的参数赋值给变量 $path_info
                    set $path_info $2;
            }
            #配置fastcgi的一些参数
            fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
            fastcgi_param SCRIPT_NAME $real_script_name;
            fastcgi_param PATH_INFO $path_info;
            ###pathinfo支持end
        fastcgi_intercept_errors on;
        fastcgi_pass   127.0.0.1:9000;
    }
    
    location ^~ /data/runtime {
    return 404;
    }
    
    location ^~ /application {
    return 404;
    }
    
    location ^~ /simplewind {
    return 404;
    }
}

复制代码
重启nginx

    # service nginx reload
# vim /var/www/html/php7.aaa.com/index.php

把下面的代码复制到这个文件 里

<?php

phpinfo();

4.查看访问http://php7.aaa.com

ok!收工!
