Configure memcached
Default configuration on AlmaLinux 9 look like the following
|
1 2 3 4 5 |
PORT="11211" USER="memcached" MAXCONN="1024" CACHESIZE="64" OPTIONS="-l 127.0.0.1,::1" |
edit configuration file
|
1 |
vi /etc/sysconfig/memcached |
Lets change cache size to 128 mb
Find
|
1 |
CACHESIZE="64" |
Replace 64 with 128
In AlmaLinux 9, memcached only listen on loop back interface IP address (127.0.0.1,::1). If your configuation don’t restrict memcache to listen to 127.0.0.1, change your options line as follows.
|
1 |
OPTIONS="-l 127.0.0.1 -U 0" |
This will restrict memcached to listen on IP address 127.0.0.1 and -U 0 disable UDP. This is done to protect memcachd installation from attacks.
Restart memcached with
|
1 |
systemctl restart memcached |
To verify memcached is running, run
|
1 2 3 |
[root@server1 ~]# netstat -lntp | grep memc tcp 0 0 127.0.0.1:11211 0.0.0.0:* LISTEN 2224258/memcached [root@server1 ~]# |
We have memcached listening on 127.0.0.1:11211
Now we have memcached deamon running. We need PHP module installed.
