centos 7
php 7.4.12
nginx 1.18
mysql 8.0.22
redis 6.0.9
git 2.24.3

首先，安装阿里的 centos 仓库。（centos 7）

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
sed -i -e \'/mirrors.cloud.aliyuncs.com/d\' -e \'/mirrors.aliyuncs.com/d\' /etc/yum.repos.d/CentOS-Base.repo
yum makecache
yum repolist

安装阿里的 epel 仓库。（centos 7）

curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

yum makecache
yum repolist

安装阿里的 remi 的仓库（centos 7）

yum install -y https://mirrors.aliyun.com/remi/enterprise/remi-release-7.rpm

sed -i  \'s/https*:\/\/rpms.remirepo.net/https:\/\/mirrors.aliyun.com\/remi/g\'  /etc/yum.repos.d/remi*
sed -i \'s/#baseurl/baseurl/g\' /etc/yum.repos.d/remi*
sed -i \'s|^mirrorlist|#mirrorlist|\' /etc/yum.repos.d/remi*

yum makecache
yum repolist

yum -y install yum-utils

安装 php（centos 7）

yum-config-manager --enable remi-php74

yum install -y php74 php74-php-devel  php74-php-fpm  php74-php-mbstring php74-php-memcache php74-php-memcached php74-php-redis  php74-php-mysqlnd  php74-php-pdo  php74-php-bcmath php74-php-xml php74-php-gd php74-php-gmp php74-php-igbinary php74-php-imagick   php74-php-mcrypt  php74-php-pdo_mysql php74-php-posix php74-php-simplexml  php74-php-opcache php74-php-xsl php74-php-xmlwriter php74-php-xmlreader php74-php-swoole php74-php-zip php74-php-phalcon  php74-php-yaml php74-php-yar php74-php-yaf php74-php-uuid

体验到快如闪电的速度了吧！

安装阿里的 composer 镜像源（centos 7）

ln -s /usr/bin/php74 /usr/bin/php

curl -o /usr/local/bin/composer https://mirrors.aliyun.com/composer/composer.phar

chmod +x /usr/local/bin/composer

composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

安装 nginx 并整合 php-fpm 服务（centos 7）

# 下面这个echo是一句命令，得一起复制

echo $\'[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true \' > /etc/yum.repos.d/nginx.repo

# 上面是一条echo命令。

yum makecache
yum install -y nginx
systemctl enable nginx
systemctl enable php74-php-fpm
sed -i \'s/user\ =\ apache/user\ =\ nginx/g\' /etc/opt/remi/php74/php-fpm.d/www.conf
sed -i \'s/group\ =\ apache/group\ =\ nginx/g\' /etc/opt/remi/php74/php-fpm.d/www.conf
sed -i \'s/listen\ =\ \/var\/opt\/remi\/php74\/run\/php-fpm\/www.sock/listen=9000/g\' /etc/opt/remi/php74/php-fpm.d/www.conf

rm -f /etc/nginx/conf.d/default.conf
vi /etc/nginx/conf.d/default.conf

/etc/nginx/conf.d/default.conf 文件内容如下

server {
    listen       80;
    server_name  localhost;
    charset utf-8 ;
    access_log  /var/log/nginx/host.access.log  main;
    root   /usr/share/nginx/html;
    index index.php  index.html index.htm;
    error_page 404  500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }
    location ~ \.php$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $realpath_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

添加一个 php 文件如下：

vi /usr/share/nginx/html/1.php

<?php
phpinfo();

启动 php-fpm 和 nginx 并验证安装正确

systemctl start nginx
systemctl start php74-php-fpm

curl localhost/1.php
# 如果能看到很多的大量输出，说明php和nginx正确安装了。

安装mysql 8（centos 7）

rpm -Uvh https://repo.mysql.com/mysql80-community-release-el7-3.noarch.rpm
sed -i \'s/enabled=1/enabled=0/\' /etc/yum.repos.d/mysql-community.repo

# 下面这句安装mysql服务，因为总下载大约530M，没有办法，时间大概3到5分钟左右。

yum --enablerepo=mysql80-community install mysql-community-server

systemctl enable mysqld
systemctl start mysqld

# 查看初始密码：
grep \'temporary password\' /var/log/mysqld.log

# 用查看到的密码进入mysql 的 shell
mysql -uroot -p

下面，整套设置新用户流程，先改初始，再加新用户并授权，再删除老用户。

set global validate_password.policy=LOW;
ALTER USER \'root\'@\'localhost\' IDENTIFIED WITH mysql_native_password BY \'aaaa1234\';
flush privileges;
create user \'root\'@\'%\' identified by \'root1234\';
ALTER USER \'root\'@\'%\' IDENTIFIED WITH mysql_native_password BY \'root1234\';
GRANT ALL PRIVILEGES ON *.* TO \'root\'@\'%\';
drop user root@localhost;
flush privileges;

退出shell，重新进入。

现在就可以直接进入shell

mysql -uroot -proot1234

# 这句话查看用户的加密方式。
select user, host, plugin from mysql.user\G;

# plugin: caching_sha2_password 表示老的MySQL客户端无法连接！

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

修改配置

vim /usr/local/php/etc/php.ini
expose_php = Off
short_open_tag = ON
max_execution_time = 300
max_input_time = 300
memory_limit = 128M
post_max_size = 32M
date.timezone = Asia/Shanghai
mbstring.func_overload=2

vim /usr/local/php/etc/php-fpm.d/www.conf
listen = /var/run/www/php-cgi.sock
listen.owner = www
listen.group = www
listen.mode = 0660
listen.allowed_clients = 127.0.0.1
pm = dynamic
listen.backlog = -1
pm.max_children = 180
pm.start_servers = 50
pm.min_spare_servers = 50
pm.max_spare_servers = 180
request_terminate_timeout = 120

# 设置用户和用户组为 nginx
user = nginx
group = nginx

路径整理
1

/etc/opt/remi/php72

php 5.3.3 以后的php-fpm 不再支持 php-fpm 以前具有的 /usr/local/php/sbin/php-fpm (start|stop|reload)等命令，所以不要再看这种老掉牙的命令了

使用信号控制

INT, TERM 立刻终止
QUIT 平滑终止
USR1 重新打开日志文件
USR2 平滑重载所有worker进程并重新载入配置和二进制模块

查看php-fpm的master进程

1	ps aux \| grep php-fpm \| grep -v grep

php-fpm-process

重启php-fpm

1 2	# 最后的一串数字就是master进程的id kill -USR2 44551
