10047:M 26 Jul 15:19:17.162 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

10047:M 26 Jul 15:19:17.162 # Server initialized

10047:M 26 Jul 15:19:17.162 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

10047:M 26 Jul 15:19:17.163 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

# ps -ef|grep redis

# wget https://github.com/nicolasff/phpredis/archive/master.zip

# unzip master.zip

# cd phpredis-master/

# /application/php/bin/phpize

# ./configure  --with-php-config=/application/php/bin/php-config

# make

# make install

# echo "extension = redis.so" >>/application/php/lib/php.ini

# killall php-fpm

# /application/php/sbin/php-fpm
