最近在家看孩子的空隙，在自己一台老旧的DELL电脑上安装了cent os7作为平常的开发服务器，废话不多说，下面开始正文：
一、首先准备下载系统镜像：CentOs7（因为我的电脑是64的所以镜像也是64的）
百度网盘下载链接：
https://pan.baidu.com/s/1gFalaeQD7ZDH2s1UO_YYIw?pwd=fo05
二、制作U盘系统盘
下载好CentOS7的系统镜像了，我们需要一个系统启动盘。
这里用到了一个工具:UltraISo.
因为是教学使用所以时间选择试用就好
注:请勿用于商用，如有版权纠纷，与博主无关，
打开UltraISO软件，选择 “文件” -> “打开” 选择linux系统镜像（iso文件）并 “打开”
选择要安装的镜像
插入U盘，选择 “启动” -> “写入硬盘镜像”，硬盘驱动器选择做为系统盘的U盘，其他选项不需要改动。
确认写入的硬盘，以及写入方式
点击 ”写入” ，等待刻录完成即可。
看到刻录成功就可以了
三、使用U盘安装CentOS7系统
1、 插入刚刚制作的系统U盘进入BIOS，更改U盘为第一启动项。f10保存并重启。
2、 进入centos安装界面。不用管有几个选项，选中第一个 按 回车键
3、 进入图形界面如果不出现报错就是成功了，可以正常安装操作系统了。
选择语言，时区
磁盘分区（因为是最小安装择软件包所有没有选）
磁盘分区（因为是最小安装择软件包所有没有选）
开始安装
设置root密码
4. 安装之后重启后关机移除U盘在开机即可正常使用。
四、开始搭建LNMP环境
因为是笔记本改的服务器一直都不会关机，这时候需要：合上笔记本盖子（显示屏关闭），但是SSH远程在操作此机器，则希望合盖不睡眠（包括网络正常使用）
编辑下列文件：/etc/systemd/logind.conf
#HandlePowerKey按下电源键后的行为，默认power off
#HandleSleepKey 按下挂起键后的行为，默认suspend
#HandleHibernateKey按下休眠键后的行为，默认hibernate
#HandleLidSwitch合上笔记本盖后的行为，默认suspend（改为lock；即合盖不休眠）在原文件中，还要去掉前面的#
运行：systemctl restart systemd-logind就会生效.
一、准备资源（源码安装）
nginx 源：https://nginx.org/download/
mysql 电脑 源：http://tel.mirrors.163.com/mysql/Downloads/
php 源：https://www.php.net/releases/
二、安装nginx
1.下载Nginx
cd /home/application/tools
wget http://nginx.org/download/nginx-1.20.0.tar.gz
tar xf nginx-1.20.0.tar.gz
2.安装Nginx依赖
pcre-devel 让nginx拥有正则的能力，rewrite等都需要正则匹配
openssl-devel 让nginx拥有开启https的能力。
yum install -y pcre-devel openssl-devel
3.创建Nginx管理用户
useradd -s /sbin/nologin -M nginx
4.编译配置Nginx
–prefix=/application/nginx-1.14.0 置编译安装目录
–user=nginx 配置nginx的管理用户为nginx用户
–group=nginx 配置nginx的管理组为nginx组
–with-http_stub_status_module 配置使用Nginx的监控模块
–with-http_ssl_module 配置应用认证模块（https需要此模块，需要openssl-devel依赖
cd /home/application/tools/nginx-1.20.0
./configure 电脑 --prefix=/application/nginx-1.14.0 --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module
5.编译安装Nginx
make && make install
6.为Nginx安装目录创建软链接（方便以后管理）
ln -s /home/application/nginx-1.20.0/ /home/application/nginx
7.为Nginx命令创建软链接加进root环境变量（方便使用）
ln -s /home/application/nginx/sbin/nginx /sbin/
8.精简化Nginx配置文件
sed -i "/^$/d;/#/d" /home/application/nginx/conf/nginx.conf
9.添加systemctl启动脚本
cat > /usr/lib/systemd/system/nginx.service << EOF
[Unit]
Description=nginx
Documentation=http://nginx.org/en/docs/
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
ExecStartPre=/application/nginx/sbin/nginx -t -c /application/nginx/conf/nginx.conf
ExecStart=/application/nginx/sbin/nginx 电脑 -c /application/nginx/conf/nginx.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
EOF
10.启动Nginx 并且 查看Nginx进程
nginx或者systemctl start nginx
ps -ef | grep nginx
11.测试Nginx服务端口(80)
ss -lnt | grep 80
12.curl测试Nginx首页(有看到Welcome to nginx!就是成功了)
curl -s 本机IP
13.把Nginx添加到启动项(在末尾添加以下命令：#开机启动Nginx nginx)
cd /etc/rc.d && chmod +x rc.local && vim rc.local
14.重新加载nginx配置
nginx -s reload
三、安装MYSQL
1.安装MySQL依赖环境
ncurses-devel提供字符终端处理库
libaio-devel包的作用是为了支持同步I/O
yum install -y bison-devel ncurses-devel libaio-devel gcc gcc-c++ automake autoconf numactl
2.删除mariadb组件电脑
rpm -qa | grep mariadb
[结果1]
[结果2]
……
yum remove [结果1] [结果2] ……
3.下载MySQL
cd /home/application/tools
wget http://tel.mirrors.163.com/mysql/Downloads/MySQL-5.7/mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz
4.解压MySQL5.7
tar xf mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz -C /home/application
mv /home/application/mysql-5.7.38-linux-glibc2.12-x86_64 /home/application/mysql-5.7.38
ln -s /home/application/mysql-5.7.38/ /home/application/mysql
5.创建管理用户&&授权
useradd -s /sbin/nologin -M mysql
chown -R mysql.mysql /home/application/mysql-5.7.38/
6.创建目录和文件并且分配属主和属组
mkdir -p /data/mysql/{data,logs}
touch /data/mysql/logs/{mysql-error.log,mysql-slow.log}
chown -R mysql.mysql /data/mysql
mkdir /var/run/mysql
chown -R mysql.mysql 电脑 /var/run/mysql
7.初始化数据库
–initialize-insecure选项参数可以不自动生成初始root密码。
/home/application/mysql/bin/mysqld --initialize-insecure --basedir=/home/application/mysql/ --datadir=/data/mysql/data --user=mysql
8.复制脚本及PATH变量赋值
cp /home/application/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod 700 /etc/init.d/mysqld
echo 'PATH=$PATH:/home/application/mysql/bin' >> /etc/profile
source /etc/profile
9.编辑配置文件
vim /etc/my.cnf
[mysql]
# CLIENT #
port = 3306
socket = /tmp/mysql.sock
[mysqld]

10.启动MySQL
/etc/init.d/mysqld start
11.初始化root密码
mysql_secure_installation
==========================================================================
secure enough. Would you like to setup VALIDATE PASSWORD plugin?
Press y|Y for Yes, any other key for No: n
New password: <==此处输入新密码（如果低于八位数密码，稍后会有系统提示）
Re-enter new password: <==此处重复输入新密码
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : n
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Success.
All done!
12.把MySQL添加进启动项
cd /etc/rc.d && chmod +x rc.local && vim rc.local
#开机启动mysql
mkdir -p /var/run/mysql
chown -R mysql.mysql /var/run/mysql
/etc/init.d/mysqld start
14.重启MySQL
/etc/init.d/mysqld restart
四、安装PHP
1.预先安装必要的依赖
yum install -y wget gcc gcc-c++ autoconf automake libtool make libxml2 libxml2-devel openssl openssl-devel sqlite-devel libcurl
2.下载解压PHP
cd /home/application/tools
wget wget https://www.php.net/distributions/php-8.1.11.tar.gz
tar xf php-8.1.11.tar.gz -C /home/application
3.编译配置php
./configure --prefix=/home/application/php-8.1.11 --with-config-file-path=/home/application/php-8.1.11/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-mysqlnd-compression-support --with-zlib --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --with-curl --enable-mbregex --enable-mbstring --enable-intl --enable-ftp --enable-gd-jis-conv --with-openssl --with-mhash --enable-pcntl --enable-sockets --enable-soap --with-gettext --enable-fileinfo --enable-opcache --with-pear --with-ldap=shared --without-gdbm
编译报错处理

重新编译，出现上面的这个代码表示编译成功
4.安装php
make && make install
5.创建软链接（方便以后管理）
ln -s /home/application/php-8.1.11/bin/php /usr/local/bin/php
6.测试
php -v
PHP 8.1.11 (cli) (built: Nov 7 2022 15:35:02) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.11, Copyright (c) Zend Technologies
7.修改配置文件
# 源码包 php-8.0.24
cp /home/application/php-8.1.11/php.ini-production /home/application/php-8.1.11/etc
cd /home/application/php-8.1.11/etc
cp php.ini-production php.ini
cd /home/application/php-8.1.11/etc
cp php-fpm.conf.default php-fpm.conf
cd /home/application/php-8.1.11/php-fpm.d
cp www.conf.default www.conf
# 修改www.conf文件
# 监听方式为sock
;listen = 127.0.0.1:9000
listen = /tmp/www.sock
8.开机自启
# 源码包 php-8.1.11/sapi/fpm
cp /home/application/php-8.1.11/sapi/fpm/php-fpm.service /usr/lib/systemd/system/php-fpm-8.1.11.service
server {
listen 80;
server_name www.paul.test;
root /home/web/wwwroot;
add_header X-Frame-Options "SAMEORIGIN";
add_header X-Content-Type-Options "nosniff";
index index.php;
charset utf-8;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location = /favicon.ico { access_log off; log_not_found off; }
location = /robots.txt { access_log off; log_not_found off; }
error_page 404 /index.php;
location ~ \.php$ {
fastcgi_pass unix:/tmp/www.sock;
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /\.(?!well-known).* {
deny all;
}
}
9.启动php-fpm
cp /home/application/php-8.1.11/sapi/fpm/php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
php-fpm的启动参数
#测试php-fpm配置/etc/init.d/php-fpm -t
/etc/init.d/php-fpm -c /home/application/php-8.1.11/etc/php.ini -y /home/application/php-8.1.11/etc/php-fpm.conf -t
#启动php-fpm /etc/init.d/php-fpm
/etc/init.d/php-fpm -c /home/application/php-8.1.11/etc/php.ini -y /home/application/php-8.1.11/etc/php-fpm.conf
五、系统部署
1. 在系统部署之前，务必使系统时间、MySQL时间、php时间与当地时间保持一致，即时区一致，比如都是东八区。
2. 防火墙
查看防火墙是否开启
firewall-cmd --state
如果没有 安装:yum install -y firewalld
启动：systemctl start firewalld
设置开机自启动：systemctl enable firewalld
这里通过开放一下httpd和php80的端口
firewall-cmd --permanent --zone=public --add-port=80/tcp
firewall-cmd --permanent --zone=public --add-port=3306/tcp
firewall-cmd --permanent --zone=public --add-port=443/tcp
重新加载防火墙
firewall-cmd --reload
六、验证
vim <网站根目录>/phpinfo.php
按i进入编辑模式输入<?php echo phpinfo(); ?>
按Esc键后，输入:wq并回车，保存关闭文件
在本地Windows主机(同局域网)，打开浏览器。
在浏览器的地址栏输入http://新安装的CentOSIP地址/phpinfo.php进行访问。
访问结果如下图所示，表示LNMP环境部署成功。
到这里CentOS7 和 LNMP服务已经基本搭建完毕了！！！
后面会持续更新各服务的自动启动相关脚本 谢谢！！！
感谢各位的阅读！相信大家都有了一定的了解，希望分享的内容对大家有所帮助！
