redis6.2.13切换到6.2.19

FAQ：
redis 6.2.13成功安装升级到6.2.19后，版本仍然显示6.2.13

1. 确认新版本的实际安装路径

# 查找新安装的 redis-server
sudo find / -name redis-server 2>/dev/null | grep 6.2.19

# 示例输出可能为：
# /usr/local/redis-6.2.19/bin/redis-server
# /opt/redis-6.2.19/src/redis-server

2. 确定系统当前调用的旧版本路径

which redis-server
# 输出示例：/usr/bin/redis-server

# 检查该文件的实际版本
/usr/bin/redis-server -v
# 应显示 6.2.13

3.清理所有旧版本痕迹

# 查找所有可能的旧版本文件
sudo find / -name "redis-server" -o -name "redis-cli" 2>/dev/null | grep -v 6.2.19

4.删除旧版本痕迹

# 删除非6.2.19版本的可执行文件（根据上一步结果操作）
sudo rm -f /path/to/old/redis-*

以下是根据查找结果执行的命令：

[root@TLYS-216-178 ~]# sudo rm -f /usr/bin/redis-server /usr/bin/redis-cli
[root@TLYS-216-178 ~]# sudo rm -f /usr/local/bin/redis-server /usr/local/bin/redis-cli
[root@TLYS-216-178 ~]# sudo rm -f /usr/local/redis/bin/redis-*
[root@TLYS-216-178 ~]# sudo rm -f /usr/local/finedo/redis/bin/redis-*
[root@TLYS-216-178 ~]# sudo rm -rf /u01/redis/redis-6.0.4 /u01/redis/redis-6.2.13

5.重建符号链接到6.2.19版本

# 确认新版本路径，"/u01/redis/redis-6.2.19/src"是redis解压包的路径
NEW_REDIS_PATH="/u01/redis/redis-6.2.19/src"

# 创建标准系统链接
sudo ln -sf ${NEW_REDIS_PATH}/redis-server /usr/local/bin/redis-server
sudo ln -sf ${NEW_REDIS_PATH}/redis-cli /usr/local/bin/redis-cli

# 可选：创建兼容性链接
sudo ln -sf ${NEW_REDIS_PATH}/redis-server /usr/bin/redis-server
sudo ln -sf ${NEW_REDIS_PATH}/redis-cli /usr/bin/redis-cli

6.再次查看redis版本

redis-cli --version

redis-cli 6.2.19
