Centos7 Installing Redis

Method One: Install with the command (provided that Epel is already installed).

To install Redis:

Yum-y Install Redis

Start/stop/restart Redis
Start the service:
1
Systemctl Start Redis.service
Stop service:

Systemctl Stop Redis.service

Restart Service:

Systemctl Restart Redis.service

Check Status:

[Email protected] ~]# systemctl status Redis.service
Redis.service-redis Persistent Key-value Database
Loaded:loaded (/usr/lib/systemd/system/redis.service; enabled)
Active:active (running) since II 2014-10-21 21:37:22 EDT; 5h 26min ago
Main pid:30413 (Redis-server)
CGroup:/system.slice/redis.service
└─30413/usr/bin/redis-server 127.0.0.1:6379

October 21:37:22 idoseek.com systemd[1]: Started Redis persistent key-value database.

Start the service with the system:

[Email protected] ~]# Systemctl enable Redis.service
Ln-s '/usr/lib/systemd/system/redis.service '/etc/systemd/system/multi-user.target.wants/redis.service '

To turn off random startup:

[Email protected] ~]# systemctl disable Redis.service
RM '/etc/systemd/system/mult (www.111cn.net) I-user.target.wants/redis.service '

Method Two: Compile and install

Download Install compile:

# wget http://download.redis.io/releases/redis-2.8.17.tar.gz
# tar Xzf redis-2.8.17.tar.gz
# CD redis-2.8.17
# make
# make Install

To set the configuration file path:

# mkdir-p/etc/redis && CP Redis.conf/etc/redis

To modify a configuration file:

# vim/etc/redis/redis.conf
Modified to: Daemonize Yes
To start Redis:

#/usr/local/bin/redis-server/etc/redis/redis.conf
#关闭服务

REDIS-CLI shutdown

Or execute shutdown in the CLI

Redis 127.0.0.1:6379> shutdown

Clear Cache

REDIS-CLI Flushall

For more documentation, refer to the "README" file in the package.

# Ss-nlp|grep Redis

Or

# Ps-ef | grep Redis

The following is an introduction to adding a Redis plugin to PHP.

Download the latest extension from official website, address: Http://pecl.php.net/package/redis or Https://github.com/phpredis/phpredis

#wget http://pecl.php.net/get/redis-2.2.5.tgz
#phpize
#./configure--prefix=/opt/redis--enable-redis--with-php-config=/opt/php/bin/php-config
#make && make Install

Add extension to php.ini and restart PHP-FPM:

Service PHP-FPM Restart

Error description

Installing the Redis 2.8.18 times wrong:

Zmalloc.h:50:31:error:jemalloc/jemalloc.h:no such file or directory
Zmalloc.h:55:2: Error: #error "Newer version of Jemalloc required"
MAKE[1]: * * * [ADLIST.O] Error 1
MAKE[1]: Leaving directory '/DATA0/SRC/REDIS-2.6.2/SRC '
Make: * * * [ALL] Error 2

Cause analysis

There is this passage in the README.

Allocator
---------

Selecting a Non-default memory allocator when building Redis are done by setting
The ' MALLOC ' environment variable. Redis is compiled and linked against LIBC
malloc by default, with the exception of Jemalloc being the default on Linux
Systems. This default is picked because Jemalloc has proven to having fewer
Fragmentation problems than libc malloc.

To force compiling against libc malloc, use:

% make MALLOC=LIBC

To compile against Jemalloc in Mac OS X systems, use:

% make Malloc=jemalloc

Said about the allocator allocator, if there is malloc this environment variable, it will be useful for this environment variable to establish redis.

And libc is not the default allocator, the default is Jemalloc, because Jemalloc is proven to have fewer fragmentation problems than libc.

But if you don't have a jemalloc and only libc of course make a mistake. So add such a parameter.

Solutions

Make MALLOC=LIBC
