CentOS 6.5下Redis开机启动配置记录

上篇“CentOS 6.5下Redis安装记录”，只是安装了，可以运行可以用了，但是系统重启之后并不会随系统自动启动，用起来很不方便，这里就把CentOS 6.5下Redis开机启动配置记录说一下。

下载安装

如果你只是执行了Make，要配置开机启动还需要执行：

sudo make install

install的时候，redis的命令会被拷贝到/usr/local/bin下面

复制配置文件到 /etc 目录下

cp redis.conf /etc

建立用户与日志目录

建议为Redis单独建立一个用户，并新建data和日志文件夹

sudo useradd redis
sudo mkdir -p /var/lib/redis
sudo mkdir -p /var/log/redis
sudo chown redis.redis /var/lib/redis
sudo chown redis.redis /var/log/redis

修改配置文件

vi /etc/redis.conf

修改绑定的IP，解决本机之外其它IP无法访问的问题（如果需要在其它电脑上访问）；

################################## NETWORK #####################################

# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all the network interfaces available on the server.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only into
# the IPv4 lookback interface address (this means Redis will be able to
# accept connections only from clients running into the same computer it
# is running).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 0.0.0.0

默认是“bind 127.0.0.1 ::1”，改为“bind 0.0.0.0”；
修改启动模式为后台启动

################################# GENERAL #####################################

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize yes

daemonize yes

修改数据文件存储位置

# The working directory.
#
# The DB will be written inside this directory, with the filename specified
# above using the 'dbfilename' configuration directive.
#
# The Append Only File will also be created inside this directory.
#
# Note that you must specify a directory here, not a file name.
dir /var/lib/redis

注意：是指定一个目录，不带文件名；

配置init脚本

vi /etc/init.d/redis

# chkconfig:   2345 90 10

# description:  Redis is a persistent key-value database

注意开头的两句：

# chkconfig:   2345 90 10

# description:  Redis is a persistent key-value database

这虽然是注释，但要是没有它，就会报错：service redis does not support chkconfig
添加执行权限

chmod +x /etc/init.d/redis

设定开机启动服务

sudo chkconfig redis on

启动,停止redis

service redis start  
service redis stop

或者：

/etc/init.d/redis start  
/etc/init.d/redis stop

测试redis

# redis-cli
127.0.0.1:6379> set key 123
OK
127.0.0.1:6379> get key
"123"
127.0.0.1:6379> exit

你也可以使用Telnet来测试：

telnet  192.168.1.100 6379

连接之后执行相同的命令就行。
