LNMP架构搭建论坛

一、Nginx的编译安装

1、#关闭防火墙
[root@localhost opt]# systemctl stop firewalld
[root@localhost opt]# setenforce 0
2、#安装依赖关系包和解压Nginx软件包
[root@localhost opt]# yum -y install pcre-devel zlib-devel gcc gcc-c++ make
cd /opt
tar zxvf nginx-1.12.0.tar.gz

3、添加 Nginx 系统服务
vim /lib/systemd/system/nginx.service
[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
4、赋权，重启服务并设置开机自启
chmod 754 /lib/systemd/system/nginx.service
systemctl start nginx.service
systemctl enable nginx.service

二、安装数据库MySQL

1、安装Mysql环境依赖包
yum -y install
ncurses
ncurses-devel
bison
cmake

2、创建运行用户
useradd -M -s /sbin/nologin mysql

3、编译安装
cd /opt
tar zxvf mysql-boost-5.7.20.tar.gz

cd /opt/mysql-5.7.20/
cmake
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock
-DSYSCONFDIR=/etc
-DSYSTEMD_PID_DIR=/usr/local/mysql
-DDEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci
-DWITH_EXTRA_CHARSETS=all
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_ARCHIVE_STORAGE_ENGINE=1
-DWITH_BLACKHOLE_STORAGE_ENGINE=1
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1
-DMYSQL_DATADIR=/usr/local/mysql/data
-DWITH_BOOST=boost
-DWITH_SYSTEMD=1

make && make install

4、修改mysql 配置文件
vim /etc/my.cnf
[client]
port = 3306
socket=/usr/local/mysql/mysql.sock

[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character-set-server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M
server-id = 1

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES

5、更改mysql安装目录和配置文件的属主属组
chown -R mysql:mysql /usr/local/mysql/
chown mysql:mysql /etc/my.cnf

6、设置路径环境变量
echo ‘export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH’ >> /etc/profile
source /etc/profile

7、初始化数据库
cd /usr/local/mysql/bin/
./mysqld
–initialize-insecure
–user=mysql
–basedir=/usr/local/mysql
–datadir=/usr/local/mysql/data

8、添加mysqld系统服务
cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
systemctl daemon-reload
systemctl start mysqld.service
systemctl enable mysqld

9、修改mysql 的登录密码
mysqladmin -u root -p password “abc123”

10、授权远程登录
mysql -u root -p

三、安装PHP

1、安装环境依赖包
yum -y install gd
libjpeg libjpeg-devel
libpng libpng-devel
freetype freetype-devel
libxml2 libxml2-devel
zlib zlib-devel
curl curl-devel
openssl openssl-devel

2、编译安装
cd /opt
tar jxvf php-7.1.24.tar.bz2

cd php-7.1.24
./configure
–prefix=/usr/local/php
–with-mysql-sock=/usr/local/mysql/mysql.sock
–with-mysqli
–with-zlib
–with-curl
–with-gd
–with-jpeg-dir
–with-png-dir
–with-freetype-dir
–with-openssl
–enable-fpm
–enable-mbstring
–enable-xml
–enable-session
–enable-ftp
–enable-pdo
–enable-tokenizer
–enable-zip

make && make install

3、路径优化
ln -s /usr/local/php/bin/* /usr/local/bin/
ln -s /usr/local/php/sbin/* /usr/local/sbin/

4、调整PHP配置文件
php有三个配置文件：
php.ini 主配置文件
php-fpm.conf 进程服务配置文件
www.conf 扩展配置文件

#调整主配置文件：
cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini
vim /usr/local/php/lib/php.ini
–1170行–修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
–939行–取消注释，修改
date.timezone = Asia/Shanghai

php -m #验证安装的模块

#调整进程服务配置文件：
cd /usr/local/php/etc/
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
–17行–去掉";"注释
pid = run/php-fpm.pid

#调整扩展配置文件：
cd /usr/local/php/etc/php-fpm.d/
cp www.conf.default www.conf

5、启动php-fpm
/usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini
netstat -anpt | grep 9000

#PHP-FPM(FastCGI Process Manager：FastCGI 进程管理器)是一个 PHPFastCGI 管理器， 由于Nginx服务器不能处理动态页面，需要由 Nginx 把动态请求交给 php-fpm 进程进行解析。

cd /opt/php-7.1.24/sapi/fpm
cp php-fpm.service /usr/lib/systemd/system/php-fpm.service
systemctl restart php-fpm.service

6、配置 Nginx 支持 PHP 解析
vim /usr/local/nginx/conf/nginx.conf
–65行–取消注释，修改
location ~ .php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name; #将 /scripts 修改为nginx的工作目录
#fastcgi_param SCRIPT_FILENAME $documen{t}_{r}oot$fastcgi_script_name; #$document_root 代表当前请求在root指令中指定的值
include fastcgi_params;
}

systemctl restart nginx.service

7、验证PHP 测试页
vim /usr/local/nginx/html/index.php

四、论坛的搭建

（1）.创建一个数据库

mysql -u root -p

（2）把bbs数据库里面所有表的权限授予给bbsuser,并设置密码
mysql> GRANT all ON bbs.* TO ‘bbsuser’@‘%’ IDENTIFIED BY ‘admin123’;
（3）刷新数据库

mysql>flush privileges;

（4）解压论坛压缩包

unzip Discuz_X2.5_SC_UTF8.zip

cd /opt/dir_SC_UTF8/
#上传站点更新包
cp -r upload/ /usr/local/httpd/htdocs/bbs
（5）切换论坛目录，更改论坛目录属主

cd /usr/local/httpd/htdocs/bbs
chown -R daemon ./config
chown -R daemon ./data
chown -R daemon ./uc_client
chown -R daemon ./uc_server/data

数据库服务器: localhost #本地架设就用localhost，如何不是在在本机上就要填写IP地址和端口号
数据库名字: bbs
数据库用户名: bbsuser
数据库密码: admin123
管理员账号: admin
管理员密码: admin123

五、shell脚本部署LNMP

将软件包放在opt目录下：

#!/bin/bash
#先配置好yum
echo -e "----正在验证当前为仅主机还是NAT模式----"
ping -c 2 -w 2 www.baidu.com &> /dev/null

if [ $? -eq 0 ];then echo -e "检测当前为NAT模式，为您配置在线yum源"
    mkdir -p /etc/yum.repos.d/repo.bak
    mv -f /etc/yum.repos.d/* /etc/yum.repos.d/repo.bak &> /dev/null
    wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo &> /dev/null

    yum clean all &> /dev/null
    yum list &> /dev/null

    echo -e "在线源已配置完成"
else
    echo -e "检测当前为仅主机模式，为您配置本地yum源"
    mount /dev/sr0 /mnt &> /dev/null
    cd /etc/yum.repos.d/
    mkdir -p /etc/yum.repos.d/repo.bak

    mv -f /etc/yum.repos.d/* /etc/yum.repos.d/repo.bak &> /dev/null
echo '[local]
name=local
baseurl=file:///mnt
enabled=1
gpgcheck=0' > /etc/yum.repos.d/local.repo
yum clean all &> /dev/null
yum makecache &> /dev/null

     df -h | grep "/mnt"

     if [ $? -ne 0 ];then
     echo -e "检测当前为仅主机模式，但光盘未挂载!"
else
     echo -e "本地yum源已配置完成"
     fi
fi
