CentOS7.9编译安装Redis6.2.5指南分享_Redis

gcc 11是自己编译安装的

所以redis的makefile找不到cc，需要手动造一个链接

cd /usr/bin
sudo ln -s /usr/local/gcc-11.2.0/bin/gcc cc

编译

 make -j7 use_systemd=yes prefix=/opt/redis/

安装

sudo make prefix=/opt/redis install

卸载

sudo make uninstall

自带的systemd启动文件有点问题，改为如下

[unit]
description=redis data structure server
documentation=https://redis.io/documentation
#before=your_application.service another_example_application.service
#assertpathexists=/var/lib/redis
wants=network-online.target
after=network-online.target
[service]
execstart=/opt/redis/bin/redis-server /opt/redis/redis.conf --supervised systemd --daemonize no
## alternatively, have redis-server load a configuration file:
#execstart=/usr/local/bin/redis-server /path/to/your/redis.conf
limitnofile=10032
nonewprivileges=yes
#oomscoreadjust=-900
privatetmp=yes
type=notify
timeoutstartsec=15
timeoutstopsec=15
umask=0077
#user=redis
#group=redis
#workingdirectory=/var/lib/redis
[install]
wantedby=multi-user.target

注意修改了timeout的值，否则会经常报timeout错误，例如

job for redis.service failed because a timeout was exceeded. see "systemctl status redis.service" and "journalctl -xe" for details.

# systemctl status redis.service
