Install failing on 2nd node

dpwhitedpwhite EntrantInactive User Role Beginner
I’m trying to stand up a 3-node PXC, MySQL 5.6 in RHEL 6.6. I was able to start the first node (172.30.200.45) OK. When I try to start the 2nd node (172.30.200.46) I’m getting this error:

[[email protected] bin]$ /etc/init.d/mysql start
Starting MySQL............. ERROR! The server quit without updating PID file (/var/lib/mysql/ldvdbamycl02.itap.purdue.edu.pid).

============================================

The my.cnf on the 2nd node is pretty simple:

[mysqld]
socket=/tmp/mysql.sock
datadir=/var/lib/mysql
basedir=/opt/mysql/Percona-XtraDB-Cluster-5.6.20-rel68.0-25.7.886.Linux.x86_64
wsrep_provider=/opt/mysql/Percona-XtraDB-Cluster-5.6.20-rel68.0-25.7.886.Linux.x86_64/lib/libgalera_smm.so
user=mysql
log_error=/var/log/mysql/error.log
wsrep_cluster_address='gcomm://172.30.200.45,172.30.200.46,172.30.200.47'
binlog_format=ROW
default_storage_engine=InnoDB
innodb_autoinc_lock_mode=2
wsrep_node_address=172.30.200.46
wsrep_sst_method=rsync
wsrep_cluster_name=mysqldevcluster1
wsrep_sst_auth="sstuser:xxxxx"
===============================================

The error log on the 2nd node looks like this:

141114 14:27:17 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

    Nevermind. I found out that socat was already using port 4444. I killed that process and it started fine!
