部署redis6.0 常見問題

問題1：在make的時候，提示如下錯誤：

server.c:5170:39: error: ‘struct redisServer’ has no member named ‘maxmemory’
if (server.maxmemory > 0 && server.maxmemory < 1024*1024) {
                                  ^
server.c:5171:176: error: ‘struct redisServer’ has no member named ‘maxmemory’
    serverLog(LL_WARNING,"WARNING: You specified a maxmemory value that is less than 1MB (current value is %llu bytes). Are you sure this is what you really want?", server.maxmemory);
                                                                                                                                                                           ^
server.c:5174:31: error: ‘struct redisServer’ has no member named ‘server_cpulist’
redisSetCpuAffinity(server.server_cpulist);

解決辦法：
出現這種錯誤是由於gcc版本太低，升級gcc

# 查看gcc版本是否在5.3以上，centos7.6默認安裝4.8.5
gcc -v
# 升級gcc到5.3及以上,如下：
升級到gcc 9.3：
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
scl enable devtoolset-9 bash
需要注意的是scl命令啟用只是臨時的，退出shell或重啟就會恢復原系統gcc版本。
如果要長期使用gcc 9.3的話：
 
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
這樣退出shell重新打開就是新版的gcc了
以下其他版本同理，修改devtoolset版本號即可
