php-admin部署-解决全部错误

网站会话保持项目：

①概述：

1、cookie：用于存放用户登录信息，基本信息

2、session：用于存放用户登录信息，基本信息

3、会话保持：会话保持/会话共享：无论用户通过那台web登录，登录状态保持不变

②会话保持方案：

1、使用ip_hash轮训算法即可，这样用户就会只访问1台

2、搭建一个存放会话的服务｛redis/mem，把所有的会话信息存放到这个服务中｝

③环境规划：

1、web01：nginx+php 9001

2、web2复制

3、slb接入

4、db1：安装redis，配置会话保持

④web站点的配置：

1、web的站点配置：｛是指向了9001不是9000因为9001要存会话｝

[[email protected] /]# cat /etc/nginx/conf.d/phpadmin.conf

server {

listen 80;

server_name www.ipran.com;

root /www/web/phpadmin;

location / {

index index.php;

}

location ~ \.php$ {

fastcgi_pass 127.0.0.1:9001;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

}

[[email protected] /]#

2、站点文件：｛修改权限和conf的地址，这个地址是redis的地址｝{下载phpamdin-5.13版本，高版本有问题｝

[[email protected] web]# ls -l

drwxr-xr-x 12 nginx nginx 4096 Jun 2122:17 phpadmin

[[email protected] web]# pwd

/www/web

[[email protected] web]# grep 'host' phpadmin/config.inc.php

$cfg['Servers'][$i]['host'] = '192.168.0.8';

// $cfg['Servers'][$i]['controlhost'] = '';

[[email protected] web]#

3、配置php的配置和php-session的配置：｛要chown-nginx的配置｝

[[email protected] /]#

[[email protected] php-fpm.d]# ll -l

total 8

-rw-r--r-- 1 nginx nginx 484 Jun 2122:14 session.conf

-rw-r--r-- 1 nginx nginx 479 Jun 319:42 www.conf

[[email protected] php-fpm.d]# pwd

/etc/php-fpm.d

[[email protected] php-fpm.d]#

[[email protected] php-fpm.d]# cat www.conf

[www]

user = www

group = www

listen = 127.0.0.1:9000

listen.allowed_clients = 127.0.0.1

pm = dynamic

pm.max_children = 50

pm.start_servers = 5

pm.min_spare_servers = 5

pm.max_spare_servers = 35

slowlog = /var/log/php-fpm/www-slow.log

php_admin_value[error_log] = /var/log/php-fpm/www-error.log

php_admin_flag[log_errors] = on

php_value[session.save_handler] = files

php_value[session.save_path] = /var/lib/php/session

php_value[soap.wsdl_cache_dir] = /var/lib/php/wsdlcache

[[email protected] php-fpm.d]#

[[email protected] php-fpm.d]# cat session.conf ｛配置标题的名字和redis的头，还有redis的地址其余的和php的配置一样｝

[session]

user = www

group = www

listen = 127.0.0.1:9001

listen.allowed_clients = 127.0.0.1

pm = dynamic

pm.max_children = 50

pm.start_servers = 5

pm.min_spare_servers = 5

pm.max_spare_servers = 35

slowlog = /var/log/php-fpm/www-slow.log

php_admin_value[error_log] = /var/log/php-fpm/www-error.log

php_admin_flag[log_errors] = on

php_value[session.save_handler] = redis

php_value[session.save_path] = tcp://192.168.0.8:6379

php_value[soap.wsdl_cache_dir] = /var/lib/php/wsdlcache

[[email protected] php-fpm.d]#

4、重启：

1.重启nginx

2.重启php

3.重启slb

5、将web1的全部配置复制一份到web2即可：｛web2执行和web1同样的操作｝

⑤配置redis：

1、安装redis

[[email protected] ~]# yum -y install redis

2、更改redisbind的地址为自身网卡的内网地址

[[email protected] ~]# grep '^bind' /etc/redis.conf

bind 192.168.0.8

[[email protected] ~]

3、重启redis：

[[email protected] ~]# systemctl start redis

[[email protected] ~]#

[[email protected] ~]# systemctl enable redis

[[email protected] ~]#

[[email protected] ~]# ps -ef |grep redis

redis 516710 Jun06 ? 00:23:46 /usr/bin/redis-sentinel *:26379 [sentinel]

redis 563271022:13 ? 00:00:01 /usr/bin/redis-server 192.168.0.8:6379

root 5981755642023:02 pts/000:00:00grep --color=auto redis

[[email protected] ~]# netstat -tupnl|grep redis

tcp 00192.168.0.8:63790.0.0.0:* LISTEN 56327/redis-server

tcp 000.0.0.0:263790.0.0.0:* LISTEN 5167/redis-sentinel

tcp6 00 :::26379 :::* LISTEN 5167/redis-sentinel

[[email protected] ~]#

⑥slb的配置：

1、slb的配置：

[[email protected] /]# cat /etc/nginx/conf.d/phpadmin.conf

upstream phpadmin_pools {

server 192.168.0.6:80;

server 192.168.0.10:80;

}

server {

listen 80;

server_name localhost;

location / {

proxy_pass http://phpadmin_pools;

proxy_set_header Host $http_host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header REMOTE-HOST $remote_addr;

}

}

[[email protected] /]#

⑥访问测试：｛公网slb的地址｝

1、120.48.15.242

2、登入redis的操作：

[[email protected] ~]# redis-cli -h 192.168.0.8

192.168.0.8:6379> keys *

1) "backup4"

2) "backup3"

3) "PHPREDIS_SESSION:08f2f00cb6a620bc9a7eb71453d36c2e"

4) "backup2"

5) "PHPREDIS_SESSION:9a93a6b7860c318ddc58e67f73fe19f5"

6) "backup1"

192.168.0.8:6379>

⑦错误展示：

1、错误1：｛看是否使能slb进入管理｝这个报错就说明没做会话保持

​ ​http://120.48.15.242/index.php?route=/​​

2、错误2：登录出现：｛权限不够，授权｝

1.提示：

session_start()：open（SESSION_FILE，O_RDWR）失败：权限被拒绝（13）

session_start()：无法读取会话数据：文件（路径：/var/lib/php/session）

2.解决：

[[email protected] php]# ls -ld /var/lib/php/session/

drwxrwx--- 2 root apache 4096 Oct 1 2020 session

drwxrwx--- 2 root apache 4096 Oct 1 2020 wsdlcache

[[email protected] php]# chown nginx.nginx session/

[[email protected] php]# ll

drwxrwx--- 2 nginx nginx 4096 Oct 1 2020 session

drwxrwx--- 2 root apache 4096 Oct 1 2020 wsdlcache

[[email protected] php]#

3、错误3：登录phpamdin使用root登录提示(HY000/2002):

1.将文件复制一份：

[[email protected] phpadmin]# cp config.sample.inc.php config.inc.php

2.修改localhost为数据库的地址：

[[email protected] phpadmin]# vi config.inc.php

30 $cfg['Servers'][$i]['host'] = '192.168.0.8';

4、错误4：登入php-admin显示：(HY000/1045): Access denied

因为数据库的用户可能没让外网访问的权限，要在mysql或者数据库里面授予外网访问权限，因为phpamdin在外网，所以要权限
