（1）官網下載下傳穩定版本
wget http://download.redis.io/releases/redis-6.0.8.tar.gz
（2）安裝文檔
1）yum安裝gcc
redis6.0.0+ '需要' gcc到'5.3及以上版本'
通過'安裝devtoolset的方式'間接更新gcc'指定'版本
------ '安裝指定版本gcc' ------
yum -y install centos-release-scl
# 安裝指定版本 yum -y install devtoolset-{7,8,9}-gcc*
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
scl enable devtoolset-9 bash
注意：scl指令啟用隻是'臨時的',退出shell或重新開機'就會恢複原系統gcc版本'
需求：如果要長期使用對應版本的gcc,寫入系統腳本,'永久生效' -->'非必須' -->'注意這裡的數字9'
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
2）編譯安裝redis
tar -zxf redis-6.0.8.tar.gz
cd redis-6.0.8
'安裝systemd的開發包'
yum install -y systemd-devel
'編譯' -->'systemd管理'
make USE_SYSTEMD=yes
'編譯安裝'到'指定目錄' -->移動檔案到'指定目錄'
make install
'進入工具目錄'
cd utils/
cp systemd-redis_server.service /etc/systemd/system/
-------'redis-trib.rb'-------
redis-6.0.8/src/redis-trib.rb
redis-trib.rb指令詳解
make PREFIX=/usr/local/redis install
make install --> '預設是移動到' --> '/usr/local/bin/' -->'跟service檔案适配'
普通使用者的身份啟動
'判斷是否有該使用者'
id redis || (groupadd redis && useradd redis -M -g redis -s /sbin/nologin)
'解釋'：useradd -M '不建立主目錄' -s '不允許登入' /sbin/nologin redis -g '加入redis組' redis
修改配置檔案
sed -i /etc/systemd/system/systemd-redis_server.service --> '修改'
'/usr/lib/systemd/system目錄'
'注意' notify 會失敗,'換成 forking 方式啟動',讓主程序'複制一個子程序'的方式執行
27
34 Type=forking
38 User=redis
39 Group=redis
------ 'redis.conf'的位置 ------
vim redis-6.0.8/redis.conf -->最好移動到/etc目錄 -->'chown redis /etc/redis.conf'
# 将 no 改為 yes,表示以'背景方式啟動'服務
225 daemonize yes
# 将 no 改為 systemd,表示以 'CentOS systemd' 系統服務方式啟動
236 supervised systemd
------ 'sentinel.conf'的位置 ------
redis-6.0.8/sentinel.conf -->-->最好移動到'/etc'目錄 -->'chown redis /etc/sentinel.conf'
service檔案
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.

redis報錯解決
其它報錯,參數覆寫
'日志檔案需要自己建立' -->并且'修改屬性'
chown redis.redis /var/log/redis-server.log
三個告警
相關報錯的處理
3）日志和rdb檔案
'預設是' --> logfile "" -->導入到'/dev/null'
logfile "/var/log/redis-servre.log"
touch /var/log/redis-servre.log
chown redis.redis /var/log/redis-servre.log
------------ 'rdb檔案' ------------
'預設' --> dir ./
dir /var/lib/redis/
mkdir -p /var/lib/redis/
chown redis.redis /var/lib/redis
------------ '之後重新開機' ------------
