[大数据]如何用systemd管理程序【redis 6为例】

说明：
实现用systemctl管理应用程序

安装包目录结构：

└── redis
    ├── install.sh
    ├── readme.txt
    ├── redis-cli
    ├── redis.conf
    ├── redis-server
    └── redis.service

下面这三个是编译 redis 6.2.6 所得，在源码src目录下

    ├── redis-cli
    ├── redis.conf
    ├── redis-server

源码地址：https://github.com/redis/redis/archive/refs/tags/6.2.6.tar.gz

编译：

CentOS下编译使用systemd先安装 systemd-devel：yum install systemd-devel
然后： make USE_SYSTEMD=yes
然后： 从src目录中摘取出来

install.sh：

#!/bin/sh
d=`date "+%Y%m%d%S"`
InstallDir="/usr/local/redis"
chmod +x redis-server

# check for root user
if [ "$(id -u)" -ne 0 ] ; then
        echo "You must run this script as root. Sorry!"
        exit 1
fi


# save old
if [ -d $InstallDir ];then
    echo "save old..."
    mv $InstallDir $InstallDir.backup.$d
fi


# install
echo "install..."
mkdir $InstallDir
mv ./* $InstallDir
cd $InstallDir
mv redis.service /etc/systemd/system/redis.service


# clean
echo "clean.."
if [ -f dump.rdb ];then
    rm -rf dump.rdb
fi
rm -rf install.sh
cd - && cd .. && rm -rf redis


# init
echo "init.."
systemctl daemon-reload
systemctl start redis
systemctl enable redis


# done
echo
echo "redis 6.2.6 installed : $InstallDir"

redis.service：

[unit]
Description=redis-server
After=network.target

[Service]
Type=
ExecStart=/usr/local/redis/redis-server /usr/local/redis/redis.conf
PrivateTmp=true
Restart=always
RestartSec=1

[Install]
WantedBy=multi-user.target

readme.txt

service of Redis 6.2.6

start:   systemctl start redis
stop:    systemctl stop redis
restart: systemctl restart redis

然后压缩：

tar -zcvf redisInstall.tar.gz redis

使用(不要放到/usr/local目录安装)：

tar -xvf redisInstall.tar.gz
cd redis
./install.sh

结果：
设置了systemctl管理，安装程序到 /usr/local/redis,查看状态如下，然后就是关注配置了

[root@localhost redisInstallPackageMake]# systemctl status redis
