LNMP搭建过程详解

LNMP搭建过程详解，验证搭建论坛

一、安装Nginx服务

准备工作：关闭防火墙和安全机制

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

1、安装依赖包

yum -y install pcre-devel zlib-devel gcc gcc-c++ make

2、创建运行用户

(Nginx 服务程序默认以 nobody 身份运行，建议为其创建专门的用户账号，以便更准确地控制其访问权限）
useradd -M -s /sbin/nologin nginx

3、编译安装

cd /opt
#拖入压缩包
tar zxvf nginx-1.12.0.tar.gz -C /opt/ #解压

cd nginx-1.12.0/ #切换到路径
./configure
–prefix=/usr/local/nginx \ #指定nginx的安装路径
–user=nginx \ #指定用户名
–group=nginx \ #指定组名
–with-http_stub_status_module #启用 http_stub_status_module 模块以支持状态统计

make -j4 && make install

./configure
–prefix=/usr/local/nginx
–user=nginx
–group=nginx
–with-http_stub_status_module

4、优化路径

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/ #让系统识别nginx的操作命令

5、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
ExecrReload=/bin/kill -s HUP $MAINPID
ExecrStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

chmod 754 /lib/systemd/system/nginx.service
systemctl start nginx.service
systemctl enable nginx.service

6、测试页:火狐浏览器

输入本机IP：192.168.80.77

补充：启动、停止 nginx 服务
nginx -t #检查配置文件是否配置正确
nginx #启动
cat /usr/local/nginx/logs/nginx.pid #先查看nginx的PID号
kill -3 <PID号>
kill -s QUIT <PID号> #停止
killall -3 nginx
killall -s QUIT nginx

二、安装MySQL服务

1、安装Mysql环境依赖包

yum -y install
gcc
gcc-c++
ncurses \ #字符终端下图形互动功能的动态库
ncurses-devel \ #ncurses开发包
bison \ #语法分析器
cmake #mysql需要用cmake编译安装

yum -y install gcc gcc-c++ 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 -j 4 && make install #编译安装

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、初始化数据化

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、添加mysql的登录密码

mysqladmin -u root -p password “abc123” ##给root账号设置密码为abc123，提示输入的是原始密码（为空）

10、授权远程登录

mysql -u root -p
grant all privileges on . to ‘root’@‘%’ identified by ‘abc123’;
#授予root用户可以在所有终端远程登录，使用的密码是abc123，并对所有数据库和所有表有操作权限

show databases; #查看当前已有的数据库

quit退出

三、安装配置PHP解析环境

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-7.1.10.tar.bz2

cd ./php-7.1.10/
./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 -j4 && 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php.ini ：

调整进程服务配置文件php-fpm.conf ：

cd /usr/local/php/etc
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
#17行取消注释“;”
pid = run/php-fpm.pid

调整扩展配置文件www.conf :

cd /usr/local/php/etc/php-fpm.d
cp www.conf.default www.conf

5、启动php-fpm

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 /usr/local/php/sbin/
php-fpm -c /usr/local/php/lib/php.ini
netstat -natp | grep 9000

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的工作目录修改为/usr/local/nginx/html
include fastcgi_params;
}

systemctl restart nginx.service

7、验证PHP测试页

vim /usr/local/nginx/html/index.php

<?php phpinfo(); ?>

浏览器访问：http://192.168.80.77/index.php

8、验证数据库工作是否正常

mysql -u root -p
CREATE DATABASE bbs;
GRANT all ON bbs.* TO ‘bbsuser’@‘%’ IDENTIFIED BY ‘admin123’;
flush privileges;
show databases; #查看有哪些数据库

vim /usr/local/nginx/html/index.php

<?php $link=mysqli_connect('192.168.80.77','bbsuser','admin123'); if($link) echo "wangdachu!"; else echo "fail!!" ?>

Y ‘admin123’;
flush privileges;
show databases; #查看有哪些数据库
