zabbix-redis

discuz论坛的搭建和wordpress的搭建思路是相同的，我们搭建一个discuz论坛并不是目的，而是想通过discuz配合redis，然后用zabbix监控redis。

1、nginx

//统一用户www，提前创建
groupadd -g 666 www;
useradd -u 666 -g 666 -M -s /sbin/nologin www;

//用官方的yum源
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
//安装
yum -y install nginx

//更改主配置文件的启动用户
[root@nginx conf.d]# vim /etc/nginx/nginx.conf 
user  www;

//编写站点文件
[root@nginx conf.d]# vim default.conf 
server {
    listen       80;
    server_name  localhost;

    location / {
        root   /code;
        index  index.php;
    }
 location ~ \.php$ {
                root /code;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                fastcgi_pass 127.0.0.1:9000;
                include fastcgi_params;
                }
}

//创建站点目录
mkdir /code


//上传discuz包，unzip解压到/code目录
wget http://download.comsenz.com/DiscuzX/3.3/Discuz_X3.3_SC_UTF8.zip
[root@nginx code]# mv discuz/* ./

//更改权限
[root@nginx code]# chown -R www:www  /code

//启动
systemctl start nginx
systemctl enable nginx

//检查
ss -tnlp | grep 80
ps aux | grep nginx

2、mariadb

//安装启动，设置密码
yum -y install mariadb-server mariadb
systemctl start mariadb
mysql_secure_installation  #初始化并设置密码

//创建wordpress数据库
create database discuz;

//创建wordpress用户对wordpress数据库的授权
grant ALL on discuz.* to discuz@'localhost' identified by 'cba-123';

3、php7.3

yum -y install epel-release
yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm 
yum -y install yum-utils   

yum install -y php73-php-fpm php73-php-cli php73-php-bcmath php73-php-gd php73-php-json php73-php-mbstring php73-php-mcrypt php73-php-mysqlnd php73-php-opcache php73-php-pdo php73-php-pecl-crypto php73-php-pecl-mcrypt php73-php-pecl-geoip php73-php-recode php73-php-snmp php73-php-soap php73-php-xml


//统一用户
rpm -ql php73-php-fpm | grep conf
/etc/opt/remi/php73/php-fpm.d/www.conf
vim /etc/opt/remi/php73/php-fpm.d/www.conf
user = www
group = www

//启动
systemctl enable php73-php-fpm
systemctl start php73-php-fpm

4、redis

//安装redis
yum -y install redis

//安装php和redis联动的模块，注意版本
yum list | grep php|grep redis
yum -y install php73-php-pecl-redis4.x86_64

//重启php
systemctl restart php73-php-fpm

//给reids设置一个密码，跨主机的话还要更改bind参数，这里不用更改
vim /etc/redis.conf 
    requirepass cba-123
systemctl restart redis
ss -tnlp | grep 6379  #redis监听到6379

//修改discuz的配置文件，让discuz连接redis
 vim /code/config/config_global.php 
$_config['memory']['redis']['server'] = '127.0.0.1';
$_config['memory']['redis']['requirepass'] = 'cba-123';

5、界面

后面就是在浏览器上访问，在界面上连接数据库。

管理员登录---全局--性能优化--内存优化--redis可以看到redis的支持关键字：

6、zabbix-redis

 ls
    redis.conf
    redis.sh
    redis.xml

//修改脚本，加上redis的密码
 vim redis.sh 
    redis-cli -a cba-123 -h $SERV -p $PORT info > $CACHE

//将配置文件copy到agent的目录下
cp redis.conf /etc/zabbix/zabbix_agentd.d/
cat /etc/zabbix/zabbix_agentd.d/redis.conf 
UserParameter=redis.discovery,/etc/zabbix/scripts/redis.sh localhost list_key_space_db
UserParameter=redis[*],/etc/zabbix/scripts/redis.sh $1 $2 $3

//根据配置文件将脚本放入正确的位置
mkdir /etc/zabbix/scripts/
cp redis.sh /etc/zabbix/scripts/

//先将模板导入到zabbix-server，修改间隔时间20s，修改宏：127.0.0.1
