centos7安装discuz全过程（含LAMP搭建）

一、搭建LAMP环境

1、安装MySQL

• 关闭selinux

setenforce 0
vi /etc/selinux/config，将SELINUX的值改为"disabled"
1
2

• 下载MySQL的RPM安装文件，地址：https://dev.mysql.com/downloads/mysql​​
  
  ​​​​​​​
• 查看是否安装mysql或者mariadb：rpm -qa | grep -i mysql (rpm -qa | grep -i mariadb)，如有则执行rpm -e --nodeps 卸载
• 解压安装包：tar -xvf mysql-5.7.39-1.el7.x86_64.rpm-bundle.tar
• 依次安装各个组件

rpm -ivh mysql-community-common-5.7.39-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.39-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-5.7.39-1.el7.x86_64.rpm 
rpm -ivh mysql-community-client-5.7.39-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.39-1.el7.x86_64.rpm

• 创建MySQL数据目录和日志目录等文件，配置MySQL各个参数

cd /
mkdir mysql
cd mysql
mkdir data
mkdir mysql-bin
chown -R mysql /mysql
chgrp -R mysql /mysql

• vim /etc/my.cnf，注意文件格式，可用nodepad++使用linux字符集来编辑

[mysqld]
datadir=/mysql/data
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
log-bin=/mysql/mysql-bin/mysql-bin
server-id=1
binlog_format=ROW
max_connections=200
default-storage-engine=INNODB
character-set-server=utf8
explicit_defaults_for_timestamp=true

[mysql]
default-character-set=utf8

[client]
port=3306
default-character-set=utf8

• MySQL命令

启动MySQL：systemctl start mysqld.service
查看MySQL：systemctl status mysqld.service
关闭MySQL：systemctl stop mysqld.service

• 设置MySQL开机自启动

systemctl enable mysqld.service
1

• 查看默认密码：grep ‘temporary password’ /var/log/mysqld.log
• 使用密码登录：mysql -uroot -p
• 更改密码策略

set global validate_password_policy=0; 
set global validate_password_length=6;
1
2

• 修改默认密码

set password for root@localhost=password('hyc@2022');
1

• 授予远程访问权限

grant all privileges on *.* to root@'%' identified by 'hyc@2022';
1

• 刷新权限

flush privileges;
1

2、安装Apache

• 安装

yum install httpd -y
1

• 启动

systemctl start httpd
systemctl enable httpd.service
1
2

• 端口暴露

firewall-cmd --permanent --zone=public --add-port=80/tcp
firewall-cmd --permanent --zone=public --add-port=80/udp
firewall-cmd --permanent --zone=public --add-port=443/tcp
firewall-cmd --permanent --zone=public --add-port=443/udp
firewall-cmd --reload

• 测试：http://localhost/ or http://server-ip-address/

3、安装PHP7.4

• 如果遇到Another app is currently holding the yum lock; waiting for it to exit…问题，则执行rm -f /var/run/yum.pid

yum -y install epel-release
yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum -y install yum-utils
yum repolist all |grep php
yum-config-manager --enable remi-php74
yum -y install php  php-cli php-fpm php-mysql php-mysqlnd php-zip php-devel php-gd php-mcrypt php-mbstring php-curl php-xml php-pear php-bcmath php-json php-redis
php -v
php --modules
systemctl start php-fpm.service
systemctl enable php-fpm.service

输入如下内容
<?php 
phpinfo();
?>

浏览器访问http://ip/testphp.php

二、安装Discuz

• 下载安装包zip文件，下载地址：https://gitee.com/3dming/DiscuzL/attach_files。参考https://blog.csdn.net/qq_62624549/article/details/124422542 https://www.dismall.com/thread-77-1-1.html
• 解压zip文件

unzip DisXXXXXX.zip
1

• 将upload这个目录下的所有文件上传到 /var/www/html/目录

cp -r /xxxx/upload/* /var/www/html/
1

• 更改文件及文件夹权限

cd /var/www/html
chmod 757 -R data/ uc_server/ config/ uc_client/
systemctl restart httpd
1

• 在浏览器中输入网址http://ip/install（LAMP服务器IP）
  
  
  
  
• 删除安装文件intall/index.php

cd install/
rm -rf index.php
1
2

• 输入网址http://ip，即可访问论坛

三、运维杂项

1. 批量导入用户到Discuz

• Discuz新增用户牵涉到两个表，需要分别插入数据（注意主外键关联）

INSERT INTO `pre_ucenter_members`(`uid`, `username`, `password`, `email`, `myid`, `myidkey`, `regip`, `regdate`, `lastloginip`, `lastlogintime`, `salt`, `secques`) VALUES (2, 'test', '0ee5320c3560cd7e48cdfee7ba0a2b72', 'huyucai@qq.com', '', '', '172.16.6.1', 1661754978, 0, 0, '28225e', '');
INSERT INTO `pre_ucenter_memberfields` VALUES (2, '');

2. 文件上传限制

• 新建临时文件目录，注意权限为755

cd /var/www/html
mkdir temp
1
2

• 查看php.ini位置
  
• 修改php.ini文件如下两个配置项，配置临时目录和最大文件大小

post_max_size =200M
file_uploads = On
upload_tmp_dir = /var/www/html/temp
upload_max_filesize = 200M
