Yum搭建LNMP环境(动、静、库分离)(week4_day5)--技术流ken

前言

本篇博客使用yum来搭建lnmp环境，将采用动态，静态以及数据库分开安装的方式即nginx,php,mysql.会被分开安装在不同的服务器之上，搭建出来一套lnmp环境，并部署wordpress进行测试。

LNMP准备环境

centos7

firewalld关闭状态

selinux关闭状态

nginx服务器IP:192.168.43.174

php、php-fpm、php-mysql服务器IP: 192.168.43.175

MySQL服务器IP:192.168.43.176

LNMP搭建

第一步：php、php-fpm、php-mysql服务器搭建

下载用于和数据库通信的php-mysql,支持php文件的php以及实现fastcgi的php-fpm

[root@server ~]# yum install php-mysql php php-fpm -y

第二步：配置php-fpm文件

主要修改12行处为本机的IP地址，24行处修改为nginx端的IP地址，保证本机有apache用户

 ; Start a new pool named 'www'.
  2 [www]
  3 
  4 ; The address on which to accept FastCGI requests.
  5 ; Valid syntaxes are:
  6 ;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on
  7 ;                            a specific port;
  8 ;   'port'                 - to listen on a TCP socket to all addresses on a
  9 ;                            specific port;
 10 ;   '/path/to/unix/socket' - to listen on a unix socket.
 11 ; Note: This value is mandatory.
 12 listen = 192.168.43.175:9000      ##这里修改为本机的IP地址
 13 
 14 ; Set listen(2) backlog. A value of '-1' means unlimited.
 15 ; Default Value: -1
 16 ;listen.backlog = -1
 17 
 18 ; List of ipv4 addresses of FastCGI clients which are allowed to connect.
 19 ; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
 20 ; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
 21 ; must be separated by a comma. If this value is left blank, conne; must be separated by a comma. If this value is left blank, connections will be
 22 ; accepted from any ip address.
 23 ; Default Value: any
 24 listen.allowed_clients = 192.168.43.174  ##修改为nginx端的IP地址
 25 
 26 ; Set permissions for unix socket, if one is used. In Linux, read/write
 27 ; permissions must be set in order to allow connections from a web server. Many
 28 ; BSD-derived systems allow connections regardless of permissions.
 29 ; Default Values: user and group are set as the running user
 30 ;                 mode is set to 0666
 31 ;listen.owner = nobody
 32 ;listen.group = nobody
 33 ;listen.mode = 0666
 34 
 35 ; Unix user/group of processes
 36 ; Note: The user is mandatory. If the group is not set, the default user's group
 37 ;       will be used.
 38 ; RPM: apache Choosed to be able to access some dir as httpd
 39 user = apache   #确保有apache用户
 40 ; RPM: Keep a group allowed to write in log dir.
 41 group = apache  #确保有apache组
...

检查是否有apache用户，如果没有需要下载httpd服务，或者自建apache用户即可

[root@server ~]# id apache
uid=998(apache) gid=48(apache) groups=48(apache)

第三步：启动php-fpm服务

监听本机的9000端口

[root@server ~]# systemctl restart php-fpm
[root@server ~]# ss -tnl | grep 9000
LISTEN     0      128    192.168.43.175:9000                     *:*     

第四步：下载nginx

在192.168.43.174服务器上面下载nginx

[root@proxy ~]# yum install nginx -y

第五步：配置nginx

添加如下一个location,fastcgi_pass执行刚才配置的php服务器端

[root@proxy ~]# vim /etc/nginx/nginx.conf
...
 server {
        listen       80;
        server_name  _;
        root         /var/www/html;
       index index.html index.php;
        # Load configuration files for the default server block.
    #    include /etc/nginx/default.d/*.conf;

        location ~ .php$ {
        fastcgi_pass 192.168.43.175:9000;
        include fastcgi.conf;
        
        }
....

第六步：检查nginx配置

[root@proxy ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

第七步：启动nginx

检查无误后启动nginx

[root@proxy ~]# systemctl restart nginx 
[root@proxy ~]# ss -tnl | lsof -i :80
COMMAND  PID  USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nginx   9433  root    6u  IPv4 188674      0t0  TCP *:http (LISTEN)
nginx   9434 nginx    6u  IPv4 188674      0t0  TCP *:http (LISTEN)

第八步：下载mysql

在mysql服务器端下载数据库

[root@agent ~]# yum install mariadb-server -y

第九步：启动数据库

[root@agent ~]# systemctl restart mariadb

第十步：建立数据库及用户

创建一个wordpress数据库，新建一个wordpress用户

[root@agent ~]# mysql -uroot -p123
Welcome to the MariaDB monitor.  Commands end with ; or g.
Your MySQL connection id is 116
Server version: 5.7.23-log MySQL Community Server (GPL)

Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

MySQL [(none)]> create database wordpress;
Query OK, 1 row affected (0.06 sec)

MySQL [(none)]> grant all on wordpress.* to wordpress@'%' identified by '123';
Query OK, 0 rows affected, 1 warning (0.07 sec)

MySQL [(none)]> flush privileges;
Query OK, 0 rows affected (0.02 sec)

经过以上十步lnmp环境就已经搭建完成

LNMP环境部署wordpress进行测试

第一步：nginx服务器端准备wordpress文件

[root@proxy ~]# cd /var/www/html/
[root@proxy html]# ls
[root@proxy html]# rz
[root@proxy html]# ls
wordpress-3.3.1-zh_CN.zip
[root@proxy html]# yum install unzip -y
[root@proxy html]# unzip wordpress-3.3.1-zh_CN.zip

第二步：php服务器端也要准备wordpress文件

至于为什么也要在php服务器端准备wordpress文件是因为nginx文件里面的配置，相当于动静分离架构，动态文件即php文件会来php服务器端来找

[root@server ~]# cd /var/www/html/
[root@server html]# ls
[root@server html]# rz
[root@server html]# ls
wordpress-3.3.1-zh_CN.zip
[root@proxy html]# yum install unzip -y
[root@server html]# unzip wordpress-3.3.1-zh_CN.zip
[root@server html]# ls
wordpress  wordpress-3.3.1-zh_CN.zip

第三步：浏览器测试

在浏览器输入nginx服务器的ip地址

点击创建一个配置文件

点击现在就开始

输入之前创建的数据库信息及用户信息，点击提交

提示创建失败，只能进行手工创建（nginx服务器端及php服务器端执行下面同样的操作）

[root@proxy html]# cd wordpress
[root@proxy wordpress]# cp wp-config-sample.php wp-config.php 
[root@proxy wordpress]# vim wp-config.php 
// ** MySQL 设置 - 具体信息来自您正在使用的主机 ** //
/** WordPress 数据库的名称 */
define('DB_NAME', 'wordpress');

/** MySQL 数据库用户名 */
define('DB_USER', 'wordpress');

/** MySQL 数据库密码 */
define('DB_PASSWORD', '123');

/** MySQL 主机 */
define('DB_HOST', '192.168.43.176');

/** 创建数据表时默认的文字编码 */
define('DB_CHARSET', 'utf8');

再次打开浏览器进行测试

根据提示输入以上信息，点击下面的安装

 

输入账号和密码进行登录即可

至此LNMP服务搭建完成
