centos下推荐使用yum包管理器来安装软件

先进行Mysql5.7安装

1.下载 MySQL yum包

wget http://repo.mysql.com/mysql57-community-release-el7-10.noarch.rpm

2.安装MySQL源

rpm -Uvh mysql57-community-release-el7-10.noarch.rpm

3.安装MySQL服务端,需要等待一些时间

yum install -y mysql-community-server

4.启动MySQL

systemctl start mysqld.service
# 或
systemctl start  mysqld

5.检查是否启动成功

systemctl status mysqld.service

6.获取临时密码，MySQL5.7为root用户随机生成了一个密码

grep 'temporary password' /var/log/mysqld.log 

7.通过临时密码登录MySQL，进行修改密码操作

mysql -uroot -p

使用临时密码登录后，不能进行其他的操作，否则会报错，这时候我们进行修改密码操作

set global validate_password_policy=0;
set global validate_password_length=1;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'yourpassword';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION;
FLUSH PRIVILEGES;
quit

8.修改配置文件 /etc/my.cnf ，在 [mysqld] 段中添加

sql_mode=NO_ENGINE_SUBSTITUTION,NO_ZERO_DATE,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER
ngram_token_size=2

9.开启开机自启动

systemctl enable mysqld
systemctl daemon-reload

10.重新启动mysql

systemctl restart mysqld.service

相关命令

systemctl start|stop|status|restart mysqld.service

安装企业级linux扩展源epel

yum install -y epel-release
yum install -y yum-utils

Nginx安装

1.安装命令

yum install -y gcc-c++ pcre pcre-develzlib zlib-developenssl openssl-devel

cd /usr/local/src
wget https://nginx.org/download/nginx-1.20.0.tar.gz
tar zxvf nginx-1.20.0.tar.gz
cd nginx-1.20.0
 ./configure --prefix=/usr/local/nginx --with-http_ssl_module
make && make install

cd /usr/local/nginx/sbin
./nginx

创建配置文件目录

mkdir -p /etc/nginx/conf.d
mkdir /var/log/nginx/
cp -rf  /usr/local/nginx/conf/* /etc/nginx/

修改主nginx配置文件 /etc/nginx/nginx.conf 内容替换为

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
} 

http

  fastcgi_buffers 4 64k;
  fastcgi_busy_buffers_size 128k;
  fastcgi_temp_file_write_size 128k;  

  gzip off;

  gzip_types       text/plain application/x-javascript text/css application/xml;


  access_log  /var/log/nginx/access.log ;
  include conf.d/*.conf;
}

启动nginx

/usr/local/nginx/sbin/nginx  -c /etc/nginx/nginx.conf

相关命令

nginx -s stop ：快速关闭Nginx，可能不保存相关信息，并迅速终止web服务。
nginx -s quit ：平稳关闭Nginx，保存相关信息，有安排的结束web服务。
nginx -s reload ：因改变了Nginx相关配置，需要重新加载配置而重载。
nginx -s reopen ：重新打开日志文件。
nginx -c filename ：为 Nginx 指定一个配置文件，来代替缺省的。
nginx -t ：不运行，而仅仅测试配置文件。nginx将检查配置文件的语法的正确性，并尝试打开配置文件中所引用到的 文件。
nginx -v：显示 nginx 的版本。
nginx -V：显示 nginx 的版本，编译器版本和配置参数

Redis安装

1.安装命令

yum install -y redis

2.修改配置文件

vi /etc/redis.conf
PS:简单的单机部署只需要把daemonize改为yes即可，更多的配置项请查阅/etc/redis.conf文件

3.启动redis

systemctl start redis

4.测试redis

redis-cli

5.相关命令

systemctl start|stop|status|restart redis

PHP安装

安装php remi源

rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum-config-manager --enable remi-php74
yum update

1.安装cmake

cd /usr/local/src
yum remove -y cmake
yum install -y gcc gcc-c++
yum install -y openssl-devel bzip2 bzip2-devel   

wget https://github.com/Kitware/CMake/releases/download/v3.21.0/cmake-3.21.0.tar.gz \
&& tar -zxf cmake-3.21.0.tar.gz \
&& cd cmake-3.21.0  \
&& ./bootstrap && make && make install

然后修改 vi /etc/profile，并加入如下内容

PATH=/usr/local/bin:$PATH
export PATH

再执行

source /etc/profile

升级 安装libzip-1.7

cd /usr/local/src
wget https://libzip.org/download/libzip-1.7.3.tar.gz \
&& tar -zxf libzip-1.7.3.tar.gz \
&& cd libzip-1.7.3

mkdir -p build && cd build \
&& cmake -DCMAKE_INSTALL_PREFIX=/usr .. \
&& make \
&& make install

2.安装php7.4并启动php-fpm

cd /usr/local/src

yum install -y  php  php-cli php-fpm
yum install -y php-zip php-mysqlnd  php-mysql php-mysqli php-devel php-gd php-mcrypt php-mbstring php-curl php-xml php-pear php-bcmath php-json
yum install -y php-pecl-redis php-pecl-swoole

systemctl start php-fpm.service
systemctl enable php-fpm
systemctl daemon-reload

3.php的配置文件和目录

/etc/php.ini
/etc/php.d/*
/etc/php-fpm.ini
/etc/php-fpm.d/*

4.相关命令

systemctl start|stop|status|restart php-fpm

测试lnmpr

1.新建nginx虚拟目录配置文件：vi /etc/nginx/conf.d/test-lnmpr.conf

server {
    listen       8080;
    server_name  localhost;
    charset UTF-8;
    location / {
        root   /var/webroot;
        index  index.php index.html index.htm;
    }

    location ~ \.php$ {
        root           /var/webroot;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /var/webroot/$fastcgi_script_name;
        include        fastcgi_params;
    }
}

2.新建php测试文件:

 mkdir  /var/webroot/
 vi /var/webroot/index.php

内容

<?php
phpinfo();

3.重新启动nginx和php-fpm

4.访问 http://localhost:8080

FAQ

1.如果出现 Connecting to localhost (localhost)|::1|:8080... failed: No route to host. 则表明nginx重启失败，
可 执行 ps aux |grep nginx 查看进程号然后执行 kill -9 进程号，再启动 nginx systemctl start nginx.service

2.出现http访问nginx访问不了的情况，请查看下防火墙设置

• 关闭firewall：

  systemctl stop firewalld.service #停止firewall
  systemctl disable firewalld.service #禁止firewall开机启动
  firewall-cmd --state #查看默认防火墙状态
