CentOS Informix如何配置主从复制

在CentOS上配置Informix主从复制涉及几个步骤。以下是一个基本的指南，帮助你设置主从复制环境：

1. 准备工作

• 确保两台服务器都已安装Informix数据库：一台作为主服务器（Primary），另一台作为从服务器（Secondary）。
• 确保两台服务器的时间同步：可以使用NTP服务来同步时间。

2. 配置主服务器

1. 编辑onconfig文件：
   • 在主服务器上找到并编辑onconfig文件，通常位于/opt/informix/etc/onconfig。
   • 确保以下参数设置正确：

     DATABASENAME=your_dbname
     HOSTNAME=primary_server_hostname
     SERVERNAME=primary_server_name
     LOGFILE=/opt/informix/log/primary.log
