LAMP+redis主从搭建discuz论坛

此实验需要三台服务器:

一台服务器如下:

192.168.72.130  安装LAMP环境

1.yum 安装AP环境:

yum install httpd httpd-devel php php-devel php-mysql -y

2.安装数据库  详见以下链接:

http://jiaxinwang.blog.51cto.com/12273793/1935065

3.启动httpd服务

systemctl start httpd

4. 关闭防火墙和selinux服务或者加上相应的端口

systemctl stop firewalld

setenforce 0

5.下载discuz网站模板(下载在/var/www/html目录下)

wget http://download.comsenz.com/DiscuzX/3.2/Discuz_X3.2_SC_UTF8.zip

6.解压

unzip Discuz_X3.2_SC_UTF8.zip

由于网站代码在upload 所以把upload文件夹的文件移动到发布目录下

7.发现目录不存在和不可写;给权限

chmod -R 757 data/ config/ uc_client/ uc_server/

setenforce 也要关掉

8.在发布目录下找到config_global.php文件修改文件

目录:/var/www/html/config

修改为:$_config['db']['1']['dbhost'] = '192.168.1.156';

9.创建数据库

数据库名:服务器的IP或者域名 192.168.72.130

数据库名:在数据库中创建个数据库

数据库用户名:root

数据库密码:123456

再加个密码,其他默认

创建数据库的命令:create database discuz;

10.当下一步时出现Host '192.168.1.156' is not allowed to connect to this MySQL server这个错误时;

解决:给数据库root一个可以远程访问的权限

grant all on *.* to root@'%' identified by '123456';

然后问题解决,下一步,等待安装完成!

11.下载redis 本实验使用的是redis-2.8.18

cd /usr/src

wget http://download.redis.io/releases/redis-2.8.18.tar.gz

解压:tar zvxf redis-2.8.18.tar.gz 进入解压目录:cd redis-2.8.18/

预编译: make PREFIX=/usr/local/redis install

安装:make && make install

12.将安装目录的bin文件的文件做个软连接到/usr/bin/下

ln -s /usr/local/redis/bin/* /usr/bin/

13.在解压目录下有redis.conf配置文件 拷贝到安装目录下

cp /usr/src/redis-2.8.18/redis.conf /etc/redis/

14.启动redis

进入配置文件

vim /etc/redis/redis.conf

将daemonize no 改为daemonize yes

保存、退出

启动接配置文件  redis-server /etc/redis/redis.conf

ps -ef | grep redis

root     53762     1  0 17:53 ?        00:00:06 redis-server *:6379

root     54130  1700  0 18:24 pts/0    00:00:00 grep --color=auto redis

15.到发布目录下修改config_global.php文件

/var/www/html/config

$_config['memory']['redis']['server'] = '192.168.1.135';####改为redis服务器IP地址

16.在redis服务器输入 redis-cli进入redis

在论坛上随便点击(产生keys值)然后在redis服务器输入keys *查看keys值

发现没有 因为php没有redis模块,要添加phpredis模块

(做个php测试页面,如果找不到redis说明没有redis模块)

17.下载安装phpredis

wget https://github.com/phpredis/phpredis/archive/3.1.2.tar.gz

tar zvxf 3.1.2.tar.gz


cd phpredis-3.1.2/


phpize(php初始化)


./configure --with-php-config=/usr/bin/php-config --enable-redis(预编译)


make && make install(安装)

18.在php配置文件中添加redis模块

vim /etc/php.ini

extension_dir = "/usr/lib64/php/modules/"

extension=redis.so

18.重启httpd服务

systemctl restart httpd

19.再去论坛点几下,产生keys值,然后去redis看下有没有keys值产生

#vim /usr/redis/redis.conf

将主库bind 127.0.0.1 改为 bind 0.0.0.0保存退出

 

#vim /usr/redis/redis.conf

从库在bind下添加一行

 启动redisz主库和从库

注:防火墙和setenforce
