UbuntuServer16.04LTSでRedisプロセスを複数立てる

More than 1 year has passed since last update.

テストサーバ(UbuntuLTS16.04)上に複数のRedisを立てたかったのでメモ

※ここでは標準の6379ポートの設定をもとに、6380ポートで立てている


redis-6380用ディレクトリの作成

sudo install -o redis -g root -m 755 -d /var/lib/redis-6380

sudo install -o redis -g root -m 755 -d /var/log/redis-6380
sudo install -o redis -g root -m 755 -d /var/run/redis-6380
sudo chown -R redis:redis /var/lib/redis-6380
sudo chown -R redis:redis /var/log/redis-6380
sudo chown -R redis:redis /var/run/redis-6380


confファイル作成

sudo cp -rf /etc/redis /etc/redis-6380

sudo sed -i 's/^pidfile .*$/pidfile \/var\/run\/redis-6380\/redis.pid/' /etc/redis-6380/redis.conf
sudo sed -i 's/^port .*$/port 6380/' /etc/redis-6380/redis.conf
sudo sed -i 's/^logfile .*$/logfile \/var\/log\/redis-6380\/redis.log/' /etc/redis-6380/redis.conf
sudo chown -R redis:redis /etc/redis-6380/redis.conf


起動ファイル作成

sudo cp -p /etc/init.d/redis-server /etc/init.d/redis-server-6380

sudo sed -i 's/^DAEMON=.*$/DAEMON=redis-server-6380/' /etc/init.d/redis-server-6380
sudo sed -i 's/^DAEMON_ARGS=.*$/DAEMON_ARGS=\/etc\/redis-6380\/redis.conf/' /etc/init.d/redis-server-6380
sudo sed -i 's/^NAME=.*$/NAME=redis-server-6380/' /etc/init.d/redis-server-6380
sudo sed -i 's/^DESC=.*$/DESC=redis-server-6380/' /etc/init.d/redis-server-6380
sudo sed -i 's/^RUNDIR=.*$/RUNDIR=\/var\/run\/redis-6380/' /etc/init.d/redis-server-6380
sudo sed -i 's/^PIDFILE=.*$/PIDFILE=\$RUNDIR\/redis-server-6380.pid/' /etc/init.d/redis-server-6380
sudo ln -s /usr/bin/redis-server /usr/bin/redis-server-6380


サービスファイル作成

sudo cp -p /lib/systemd/system/redis-server.service /lib/systemd/system/redis-server-6380.service

sudo vi /lib/systemd/system/redis-server-6380.service

↓以下を反映 ※sedでやりたかったけど力尽きた

[Service]

Type=forking
ExecStart=/usr/bin/redis-server-6380 /etc/redis-6380/redis.conf
PIDFile=/var/run/redis-6380/redis-server-6380.pid

ExecStop=/bin/kill -s TERM $MAINPID
ExecStopPost=-/bin/run-parts --verbose /etc/redis-6380/redis-server-6380.post-down.d

ReadWriteDirectories=-/var/log/redis-6380
ReadWriteDirectories=-/var/run/redis-6380
CapabilityBoundingSet=~CAP_SYS_PTRACE

# redis-server writes its own config file when in cluster mode so we allow
# writing there (NB. ProtectSystem=true over ProtectSystem=full)
ProtectSystem=true
ReadWriteDirectories=-/etc/redis-6380

[Install]
WantedBy=multi-user.target
Alias=redis-6380.service


pidファイルのディレクトリ自動作成設定

$ sudo vim /etc/tmpfiles.d/redis-6380.conf

以下を反映

d /var/run/redis-6380 0775 redis redis

※Linuxカーネルのあるバージョンから/var/runがtmpfs上に置かれる設定になったので必要

サービス起動

sudo service redis-server-6380 start


プロセス確認

ps aux | grep 6380


アクセス確認

redis-cli -p 6380
