搭建LNMP架构

安装mysql

1.上传mysql软件包，关闭防火墙和核心防护

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

2.安装环境依赖包，桌面安装可能有自带的数据库除

删除mariadb数据库
yum remove mariadb* -y
安装依赖环境
yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake openssl-devel

3.配置软件模块

先解压软件包
tar -xf  mysql-boost-5.7.44.tar.gz

配置软件模块
cd mysql-5.7.44
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 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1

4.编译及安装

make -j 2 && make install

useradd -M -s /sbin/nologin  mysql

6.修改mysql 配置文件

vim /etc/my.cnf    

[client]
port = 3306
socket=/usr/local/mysql/mysql.sock

[mysql]
port = 3306
socket = /usr/local/mysql/mysql.sock
auto-rehash

[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character-set-server=utf8mb4
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
max_connections=4096
default-storage-engine=INNODB
max_allowed_packet=32M
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

7.更改mysql安装目录和配置文件的属主属组

useradd -M -s /sbin/nologin mysql

chown -R mysql:mysql /usr/local/mysql/

chown mysql:mysql /etc/my.cnf

8.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

9.初始化数据库

./mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data

10.添加mysqld系统服务

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/

systemctl daemon-reload(刷新识别)
systemctl start mysqld.service(开启服务)
systemctl enable mysqld(开机自启动)

netstat -anpt | grep 3306(查看端口)

11.修改mysql 的登录密码

mysqladmin -u root password "admin123"

12.授权远程登录

cd /usr/local/mysql/bin/

mysql -u root -padmin123
grant all privileges on *.* to 'root'@'%' identified by 'admin123';
quit

安装nginx

1.上传nginx软件包，关闭防火墙和核心防护

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

2.安装环境依赖包

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

3.创建运行用户、组

useradd -M -s /sbin/nologin nginx

4.配置软件模块

tar xf nginx-1.26.2.tar.gz

cd nginx-1.26.2/ 

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

5.安装编译

make && make install

6.让系统识别nginx的操作命令

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

7.设置syetemctl管理服务

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

chmod 754 /lib/systemd/system/nginx.service

systemctl start nginx.service
systemctl enable nginx.service

netstat -lntp | grep nginx

安装php

1.上传php软件包，关闭防火墙和核心防护

systemctl stop firewalld
systemctl disable firewalld

yum -y install rpcbind nfs-utils(php和nginx安装)

vim /etc/exports（nginx机器）

/usr/local/nginx/html 192.168.110.50(rw,sync)

systemctl enable --now rpcbind nfs

showmount -e 192.168.110.60（php机器）
