CentOS8 Nginx配置php-fpm

https://wiki.miyond.com/?p=316

nginx 中 fastcgi_pass配置为unix:/tmp/php-fpm.sock与127.0.0.1:9000区别

https://blog.csdn.net/resilient/article/details/109850729 

nginx中的 fastcgi_pass为什么有时候是unix:/tmp/php-fpm.sock，有时候是127.0.0.1:9000
这牵扯到了nginx和php的通信模式，上面所列的就是这两种，一种是利用系统本身socket的，一种是利用tcp协议的
两种协议有区别，
UNIX Domain Socket不经过网络，只是在系统内部进行通信，适用于php和nginx都装在同一台linux服务器上
tcp通信协议的也就是fastcgi_pass模式的既适用于php和nginx都装在同一台linux服务器上，同时又适用于不在同一台服务器上的，一般在同一个局域网中，也就是127.0.0.1的意义了
当然我们在真正的php搭建服务器环境的时候，具体用那种，就要看php-fpm.conf中使用的是哪种了
tcp方式:
php-fpm.conf: listen = 127.0.0.1:9000
nginx.conf: fastcgi_pass 127.0.0.1:9000;
UNIX Domain Socket方式:
php-fpm.conf: listen = /tmp/php-fpm.sock
nginx.conf: fastcgi_pass unix:/tmp/php-fpm.sock;
在我们真正实例中多数都是装在同一台服务器上，所以选择UNIX Domain Socket是比较合适的选择，因为这样可以避免数据传输经过tcp层造成导致TIME_WAIT连接过多的问题。
具体两个传输方式的流程如下
1.1 TCP Socket(本地回环127.0.0.1)方式的数据传输:
Nginx <=> socket <=> TCP/IP <=> socket <=> PHP-FPM
1.2 TCP Socket(Nginx和PHP-FPM位于不同服务器)的数据传输:
Nginx <=> socket <=> TCP/IP <=> 物理层 <=> 路由器 <=> 物理层 <=> TCP/IP <=> socket <=> PHP-FPM
2 UNIX Domain Socket方式的数据传输:
Nginx <=> socket <=> PHP-FPM

空密码登录，更新root密码，更新可以外部连接，flush 权限。

[root@scts08t ~]# mysql -uroot -p -hlocalhost

mysql> show databases;

mysql> use mysql;

mysql> alter user user() identified by "ar=vW0cgAyu_8888";

mysql> update mysql.user set host='%' where user='root';

mysql> flush privileges;

方案二， mysql-8.0.31-1.el8.x86_64.rpm-bundle.tar下载解压

https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.31-1.el8.x86_64.rpm-bundle.tar

方法一, 修改mysql 8.0 root 密码

1、centos8.2环境下，按顺序如下安装mysql文件包

[root@centos82-scts08t opt]# more setup.sh 

#/bin/bash
rpm -ivh /opt/mysql-community-client-plugins-8.0.31-1.el8.x86_64.rpm
rpm -ivh /opt/mysql-community-common-8.0.31-1.el8.x86_64.rpm
rpm -ivh /opt/mysql-community-libs-8.0.31-1.el8.x86_64.rpm
rpm -ivh /opt/mysql-community-client-8.0.31-1.el8.x86_64.rpm
rpm -ivh /opt/mysql-community-icu-data-files-8.0.31-1.el8.x86_64.rpm
rpm -ivh /opt/mysql-community-server-8.0.31-1.el8.x86_64.rpm
tar -zxvf /opt/apache-tomcat-10.0.27.tar.gz -C /opt
tar -zxvf /opt/nginx-1.23.2.tar.gz -C /opt
unzip /opt/phpMyAdmin-5.2.0-all-languages.zip -d /opt
systemctl stop firewalld.service
systemctl disable firewalld.service

2、安装后检查mysql清单

[root@centos82-scts08t opt]# rpm -qa |grep mysql
mysql-community-client-8.0.31-1.el8.x86_64
mysql-community-client-plugins-8.0.31-1.el8.x86_64
mysql-community-icu-data-files-8.0.31-1.el8.x86_64
mysql-community-common-8.0.31-1.el8.x86_64
mysql-community-server-8.0.31-1.el8.x86_64
mysql-community-libs-8.0.31-1.el8.x86_64

3、重启mysql server

[root@centos82-scts08t ~]# systemctl restart mysqld.service

4、查找密码，新版本密码方式改变了，shit mysql installation，fuck Larry Ellison

[root@centos82-scts08t ~]# grep password /var/log/mysqld.log

2022-11-01T11:46:27.017354Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: ar=vW0cgAyu_

5、[root@centos82-scts08t ~]# mysql -uroot -p密码 -hlocalhost

mysql> show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

意思首先得强制改密码，还得复杂，草泥马。

mysql> alter user user() identified by " caonima ";
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

mysql> alter user user() identified by " ar=vW0cgAyu_8888 ";

6、设置允许远程连接MySQL 8，并立即生效

mysql> use mysql;

mysql> update mysql.user set host='%' where user='root';

mysql> flush privileges;
7、

方法二, 修改mysql 8.0 root 密码

1、centos8.2环境下，按顺序如下安装mysql文件包（同上）

2、 mysql 8.0.26 修改/etc/my.cnf文件，加入skip-grant-tables后重启mysql

[root@centos82-scts08t ~]# echo "skip-grant-tables"  >> /etc/my.cnf

3、mysql重启

[root@centos82-scts08t ~]# systemctl restart mysqld.service

4、mysql无密码进入，直接回车

[root@centos82-scts08t ~]# mysql -uroot -p -h127.0.0.1

RROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1:3306'

[root@centos82-scts08t ~]# mysql

5、mysql修改密码，https://download.csdn.net/download/weixin_38501206/12824626

mysql> select host,user,authentication_string,plugin from user;       --查询root的authentication_string密码

mysql> update user set authentication_string='' where user='root';  -- 先强制置空这个B养的加密密码

mysql> select host,user,authentication_string,plugin from user;

6、然后注释/etc/my.cnf 中 skip-grant-tables行 

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
#skip-grant-tables

7、再重启mysql进入修改成新root密码。

[root@centos85 ~]# systemctl restart mysqld.service

8、再无密码进入修改密码，至少8位数，又是他妈的烦神。

mysql> alter user user() identified by "caonima.com";

mysql> alter user 'root' identified by "caonima.com";

mysql> flush privileges;

9、创建远程用户，再授权

mysql> create user 'root'@'%' identified by '密码';
mysql> grant all privileges on *.* to 'root'@'%' with grant option;
mysql> flush privileges;

10、检查ok，远程连接验证ok。

mysql> select User,Host from user;

centos8.5 部署nginx 1.14.1 + php环境配置

1、安装nginx

[root@scts08t ~]# yum install -y nginx.x86_64

[root@scts08t ~]# nginx -v
nginx version: nginx/1.14.1

2、安装php相关环境

[root@scts08t ~]# yum install php php-fpm php-json php-mysqlnd  php-mbstring.x86_64 -y

[root@scts08t ~]#  /usr/sbin/php-fpm -t   #检测/etc/php-fpm.conf 配置文件

3、配置nginx

[root@scts08t ~]# vim /etc/nginx/nginx.conf  #配置nginx + php结合

        #fastcgi_param SCRIPT_FILENAME  /scripts$fastcgi_script_name;

centos8.5 部署phpmyadmin 5.12


1、下载文件


[root@scts08t ~]# wget -c https://files.phpmyadmin.net/phpMyAdmin/5.2.0/phpMyAdmin-5.2.0-all-languages.zip -P /opt


2、释放目录


[root@scts08t ~]# unzip -t /opt/phpMyAdmin-5.2.0-all-languages.zip


[root@scts08t ~]# unzip /opt/phpMyAdmin-5.2.0-all-languages.zip -d /opt/phpmyadmin


查看nginx、php-fpm进程并查看log


[root@centos82-scts08t ~]#   ps -ef |grep nginx; ps -ef |grep php;tail -f /var/log/nginx/*.log;tail -f /var/log/php-fpm/error.log 


 temp nginx.conf
