升级启动盘url-(升级启动盘是什么意思)

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 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 --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 -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(在末尾添加以下电脑命令：#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

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/ 电脑 /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 /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]

# GENERAL #

user = mysql

default-storage-engine = InnoDB

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.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y

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
