LAMP+redis主從搭建discuz論壇

此實驗須要三臺服務器:php

一臺服務器以下:html

192.168.72.130  安裝LAMP環境mysql

1.yum 安裝AP環境:linux

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

2.安裝數據庫  詳見如下連接:git

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

3.啓動httpd服務redis

systemctl start httpd

4. 關閉防火牆和selinux服務或者加上相應的端口sql

systemctl stop firewalld

setenforce 0

5.下載discuz網站模板(下載在/var/www/html目錄下)數據庫

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

6.解壓

unzip Discuz_X3.2_SC_UTF8.zip

因爲網站代碼在upload 因此把upload文件夾的文件移動到發佈目錄下

7.發現目錄不存在和不可寫;給權限

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

setenforce 也要關掉

8.在發佈目錄下找到config_global.php文件修改文件

目錄:/var/www/html/config

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

9.建立數據庫

數據庫名:服務器的IP或者域名 192.168.72.130

數據庫名:在數據庫中建立個數據庫

數據庫用戶名:root

數據庫密碼:123456

再加個密碼,其餘默認

建立數據庫的命令:create database discuz;

10.當下一步時出現Host '192.168.1.156' is not allowed to connect to this MySQL server這個錯誤時;

解決:給數據庫root一個能夠遠程訪問的權限

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

而後問題解決,下一步,等待安裝完成!

11.下載redis 本實驗使用的是redis-2.8.18

cd /usr/src

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

解壓:tar zvxf redis-2.8.18.tar.gz 進入解壓目錄:cd redis-2.8.18/

預編譯: make PREFIX=/usr/local/redis install

安裝:make && make install

12.將安裝目錄的bin文件的文件作個軟鏈接到/usr/bin/下

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

13.在解壓目錄下有redis.conf配置文件 拷貝到安裝目錄下

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

14.啓動redis

進入配置文件

vim /etc/redis/redis.conf

將daemonize no 改成daemonize yes

保存、退出

啓動接配置文件  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.到發佈目錄下修改config_global.php文件

/var/www/html/config

$_config['memory']['redis']['server'] = '192.168.1.135';####改成redis服務器IP地址

16.在redis服務器輸入 redis-cli進入redis

在論壇上隨便點擊(產生keys值)而後在redis服務器輸入keys *查看keys值

發現沒有 由於php沒有redis模塊,要添加phpredis模塊

(作個php測試頁面,若是找不到redis說明沒有redis模塊)

 

17.下載安裝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(預編譯)

 
 

make && make install(安裝)

18.在php配置文件中添加redis模塊

vim /etc/php.ini

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

extension=redis.so

18.重啓httpd服務

systemctl restart httpd

19.再去論壇點幾下,產生keys值,而後去redis看下有沒有keys值產生

127.0.0.1:6379> 

#vim /usr/redis/redis.conf

將主庫bind 127.0.0.1 改成 bind 0.0.0.0保存退出

 

#vim /usr/redis/redis.conf

從庫在bind下添加一行

 

 啓動redisz主庫和從庫

注:防火牆和setenforce
