虽然RHEL/CentOS 6开始默认使用rsyslog作为系统日志服务,不过,也可以部署syslog-ng来替代。

  • RHEL/CentOS 7需要从EPEL安装
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum install syslog-ng
  • 在Fedora中可以直接安装
yum install syslog-ng

安装了以下软件包

 eventlog          x86_64         0.2.13-7.fc23            fedora          24 k
 ivykis            x86_64         0.36.2-5.fc23            fedora          40 k
 libnet            x86_64         1.1.6-10.fc23            fedora          64 k
 syslog-ng         x86_64         3.6.2-3.fc23             fedora         492 k
