This article mainly introduces how to configure the keepalived log for other paths in centos7, which has a certain reference value, and interested friends can refer to it. I hope you will gain a lot after reading this article.

Keepalived installation:

Cd. / configure-- prefix=/usr/local/keepalived make & & make install mkdir / etc/keepalivedmkdir / etc/keepalived/scriptscp / usr/local/keepalived/etc/keepalived/keepalived.conf / etc/keepalived/cp / root/keepalived-2.0.6/keepalived/etc/init.d/keepalived / etc/init.d/cp / usr/local/keepalived/sbin/keepalived / sbin/keepalivedcp / usr/local/keepalived/etc/sysconfig/keepalived / etc/sysconfig/chmod + x / etc/init.d/keepalived

Since keepalived logs are written to / var/log/message by default, we need to split this out.

Under centos 6, you can:

(1) modify the / etc/sysconfig/keepalived file first, comment out the following, and add the following:

# KEEPALIVED_OPTIONS= "- D" KEEPALIVED_OPTIONS= "- D-d-S 0"

(2) secondly, modify the / etc/rsyslog.conf file and add the following:

Local0.* / var/log/keepalived.log

Under centos 7, you also need to modify the / lib/systemd/system/keepalived.service file:

Centos 7 is used. Because centos 7 uses systemctl and calls service through systemctl, the / lib/systemd/system/keepalived.service file needs to be modified.

Put the inside:

EnvironmentFile=-/usr/local/keepalived/etc/sysconfig/keepalivedExecStart=/usr/local/keepalived/sbin/keepalived $KEEPALIVED_OPTIONS

Modified to:

EnvironmentFile=/etc/sysconfig/keepalivedExecStart=/sbin/keepalived $KEEPALIVED_OPTIONS

Then reload service:

Systemctl daemon-reload

The whole idea is

1. Launch via systemctl start keepalived

two。 When you start keepalived, you will read the service configuration file: / lib/systemd/system/keepalived.service

3. In the configuration file of service:

3.1Boot file path ExecStart=/sbin/keepalived $KEEPALIVED_OPTIONS, that is, the startup mode is started with parameters in the environment variable file

Read the environment variable parameter EnvironmentFile=/etc/sysconfig/keepalived.

4. The $KEEPALIVED_OPTIONS parameter is configured in / etc/sysconfig/keepalived; we configure KEEPALIVED_OPTIONS= "- D-d-S 0"; and-S is the facility,0 of syslog to put in local0, and configure local0.* / var/log/keepalived.log in / etc/rsyslog.conf

5. So, write a journal and go to / var/log/keepalived.log.
