使用Systemd启动Redis

Centos7使用了systemd来启动守护进程，用来取代传统的init启动方式的

通过编译安装的Redis需要设置启动脚本来实现systemd启动，从而可以开机自启

编译

编译的时候，需要加入对systemd的支持

# libsystemd-dev on Debian/Ubuntu or systemd-devel on CentOS
yum install systemd-devel 
make USE_SYSTEMD=yes  PREFIX=/usr/local/redis/ install

否则使用systemd启动后，Redis日志中会有如下的报错：

systemd supervision requested or auto-detected, but Redis is compiled without libsystemd support!

参考：redis的systemd启动

配置

参考：Redis安装配置

创建需要的文件夹：

cd /usr/local/redis/
mkdir run
mkdir config
mkdir log
mkdir data
mkdir scripts

配置文件范例：

bind * -::*
protected-mode no
port 8000
daemonize no
pidfile "/usr/local/redis/run/redis_8000.pid"
loglevel notice
logfile "/usr/local/redis/log/redis8000.log"
save 3600 1
save 300 100
save 60 10000
stop-writes-on-bgsave-error no
dbfilename "dump8000.rdb"
dir "/usr/local/redis-6.2.3/data"
requirepass "monkey"
maxclients 1000
maxmemory 24gb
appendonly yes
appendfilename "appendonly8000.aof"
appendfsync everysec
no-appendfsync-on-rewrite no
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 1gb
aof-load-truncated yes
aof-use-rdb-preamble yes
supervised systemd
