这破站 CentOS 7手动编译安装Redis 6.2
一般通过仓库直接安装的Redis版本都比较老，所以想要用新版本的软件还是得自己动手。安装了6.2版本的Redis，并使用systemd管理。踩了些坑，记录一下

[root@localhost soft]# 如果没有编译工具，先安装一个gcc：
[root@localhost ~]# yum install gcc -y然后编译，由于想要systemd的支持，所以用make USE_SYSTEMD=yes编译：
[root@localhost soft]# cd redis-6.2.1
[root@localhost redis-6.2.1]# ls

[root@localhost redis-6.2.1]# 嗯，报错了，正常，解决它。看报错的部分提示#include <systemd/sd-daemon.h>，去GitHub的README中找找，发现需要安装依赖：
To build with systemd support, you'll need systemd development libraries (such as libsystemd-dev on Debian/Ubuntu or systemd-devel on CentOS)
要使用systemd支持进行build，需要systemd开发库（Debian/Ubuntu上是libsystemd-dev，CentOS上是systemd-devel）
那就装一下：
[root@localhost redis-6.2.1]# yum search systemd-devel
...
systemd-devel.i686 : Development headers for systemd
systemd-devel.x86_64 : Development headers for systemd
...
[root@localhost redis-6.2.1]# yum install systemd-devel -y
...然后重新编译，在编译前需要清理一下刚刚失败的时候产生的缓存，不然会一直编译失败，在README中也能找到清理的命令：
$ make distclean接着再编译，不出意外就可以编译成功了
$ make USE_SYSTEMD=yes
...

Hint: It's a good idea to run 'make test' ;)

这些编译好的文件总不能和源码放一起用吧，需要放我们指定的目录，这里以/opt/redis为例，将可执行文件复制过去并查看：

[root@localhost redis-6.2.1]# ls /opt/redis/bin/
redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server
[root@localhost redis-6.2.1]# 然后就是用systemd管理Redis了，在Ubuntu和Debian系统下可以使用utils目录下的install_server.sh脚本安装，可惜我用的是CentOS，只能自己动手了。首先尝试运行一下这个脚本
[root@localhost utils]# ./install_server.sh
Welcome to the redis service installer
This script will help you easily set up a running redis server
This systems seems to use systemd.
Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!
[root@localhost utils]# 虽然不支持，但是提示我们目录下有现成的配置文件，改改就能用。哎呀，Ctrl CV嘛，这个我熟。将Systemd的配置改改文件路径，最终如下所示：
[root@localhost utils]# cp systemd-redis_server.service /etc/systemd/system/redis_6379.service
[root@localhost utils]# vim /etc/systemd/system/redis_6379.service
1 # example systemd service unit file for redis-server
2 #
3 # In order to use this as a template for providing a redis service in your
4 # environment, _at the very least_ make sure to adapt the redis configuration
5 # file you intend to use as needed (make sure to set "supervised systemd"), and
6 # to set sane TimeoutStartSec and TimeoutStopSec property values in the unit's
7 # "[Service]" section to fit your needs.
8 #
9 # Some properties, such as User= and Group=, are highly desirable for virtually
10 # all deployments of redis, but cannot be provided in a manner that fits all
11 # expectable environments. Some of these properties have been commented out in
12 # this example service unit file, but you are highly encouraged to set them to
13 # fit your needs.
14 #
15 # Please refer to systemd.unit(5), systemd.service(5), and systemd.exec(5) for
16 # more information.

44 WantedBy=multi-user.target将上面配置里的一些目录和文件搞一搞：
[root@localhost redis-6.2.1]# cp ./redis.conf /etc/redis/redis_6379.conf
[root@localhost redis-6.2.1]# mkdir /var/lib/redis_6379
[root@localhost redis-6.2.1]# 再改改配置文件：redis_6379.conf
1 # Redis configuration file example.
2 #
3 # Note that in order to read the configuration file, Redis must be
4 # started with the file path as first argument:
5 #
6 # ./redis-server /path/to/redis.conf
...
96 # Accept connections on the specified port, default is 6379 (IANA #815344).
97 # If port 0 is specified Redis will not listen on a TCP socket.
98 port 6379
...
242 ################################# GENERAL #####################################
243
244 # By default Redis does not run as a daemon. Use 'yes' if you need it.
245 # Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
246 # When Redis is supervised by upstart or systemd, this parameter has no impact.
247 daemonize no
248
249 # If you run Redis from upstart or systemd, Redis can interact with your
250 # supervision tree. Options:
251 # supervised no - no supervision interaction
252 # supervised upstart - signal upstart by putting Redis into SIGSTOP mode
253 # requires "expect stop" in your upstart job config
254 # supervised systemd - signal systemd by writing READY=1 to $NOTIFY_SOCKET
255 # on startup, and updating Redis status on a regular
256 # basis.
257 # supervised auto - detect upstart or systemd method based on
258 # UPSTART_JOB or NOTIFY_SOCKET environment variables
259 # Note: these supervision methods only signal "process is ready."
260 # They do not enable continuous pings back to your supervisor.
261 #
262 # The default is "no". To run under upstart/systemd, you can simply uncomment
263 # the line below:
264 #
265 # supervised auto
266 supervised systemd
...
290 # Specify the log file name. Also the empty string can be used to force
291 # Redis to log on the standard output. Note that if you use standard
292 # output for logging but daemonize, logs will be sent to /dev/null
293 logfile "/var/log/redis_6379.log"
294
...重点是将supervised设置为systemd，不然起不来。有一点注意一下，上文中提到：当Redis由upstart或systemd管理时，daemonize参数就没有影响了。logfile为空字符串时，日志将输出到标准输出。其他的配置根据需求改即可。

最后：
虽然官方写了make USE_SYSTEMD=yes可以获得sytemd支持，但是我直接make编译也能使用systemd管理，不知道这两种方式编译的区别在哪，有大佬知道麻烦告知一下。
