在Debian上实现CXImage的高可用性,可以遵循以下步骤:
sudo apt update
sudo apt install nginx php-fpm mariadb-server
sudo systemctl start mariadb
sudo systemctl enable mariadb
sudo mysql_secure_installation
CREATE DATABASE cximage_db;
CREATE USER 'cximage_user'@'localhost' IDENTIFIED BY 'your_password';
GRANT ALL PRIVILEGES ON cximage_db.* TO 'cximage_user'@'localhost';
FLUSH PRIVILEGES;
wget https://example.com/cximage.zip
unzip cximage.zip -d /var/www/html
/etc/php/7.4/fpm/php.ini文件,确保以下参数设置正确:upload_max_filesize = 10M
post_max_size = 10M
sudo systemctl restart php7.4-fpm
sudo nano /etc/nginx/sites-available/cximage
添加以下内容:server {
listen 80;
server_name your_domain.com;
root /var/www/html/cximage;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.4-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
sudo ln -s /etc/nginx/sites-available/cximage /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginx
使用Nginx作为反向代理和负载均衡器:
sudo apt install keepalived
/etc/keepalived/keepalived.conf文件,添加以下内容:vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass your_password
}
virtual_ipaddress {
192.168.1.100
}
}
sudo systemctl start keepalived
sudo systemctl enable keepalived
配置主从复制以实现数据库的高可用性:
/etc/mysql/my.cnf文件,添加以下内容:server-id = 1
log_bin = /var/log/mysql/mysql-bin.log
binlog_do_db = cximage_db
sudo systemctl restart mariadb
CREATE USER 'replicator'@'%' IDENTIFIED BY 'your_password';
GRANT REPLICATION SLAVE ON *.* TO 'replicator'@'%';
FLUSH PRIVILEGES;
SHOW MASTER STATUS;
/etc/mysql/my.cnf文件,添加以下内容:server-id = 2
relay_log = /var/log/mysql/mysql-relay-bin.log
log_bin = /var/log/mysql/mysql-bin.log
binlog_do_db = cximage_db
read_only = 1
sudo systemctl restart mariadb
CHANGE MASTER TO
MASTER_HOST='master_ip',
MASTER_USER='replicator',
MASTER_PASSWORD='your_password',
MASTER_LOG_FILE='mysql-bin.000001',
MASTER_LOG_POS=107;
START SLAVE;
sudo apt install nagios3 nagios-plugins
通过以上步骤,你可以在Debian上实现CXImage的高可用性。确保定期检查和更新系统及软件包,以保持系统的稳定性和安全性。
