Centos8 Redis7

一 配置（可能用到）

1. 将 Linux 内核超量使用内存设置设置为1，修改/etc/sysctl.conf，添加vm.overcommit_memory = 1。然后重启或使用命令 sysctl vm.overcommit_memory=1 使之生效。
2. 关闭Linux特性Transparent Huge Pages：
   echo never > /sys/kernel/mm/transparent_hugepage/enabled

二 Redis简单安装

1.下载

wget https://download.redis.io/redis-stable.tar.gz

2.编译

tar -xzvf redis-stable.tar.gz
cd redis-stable
make

以下为拓展命令
编译支持TLS

make BUILD_TLS=yes

编译支持systemd，需要安装systemd开发环境库，Debian/Ubuntu ：libsystemd-dev，CentOS ：systemd-devel

make USE_SYSTEMD=yes

追加后缀

make PROG_SUFFIX="-alt"

编译32位

make 32bit

32位编译报错，安装libc6-dev-i386 或 g+±multilib，清理编译文件后

make CFLAGS="-m32 -march=native" LDFLAGS="-m32"

对编译文件清理

make distclean

空间配置器（Allocator）
Linux默认使用jemalloc，比libc malloc内存碎片化问题小。

To force compiling against libc malloc, use:

make MALLOC=libc

To compile against jemalloc on Mac OS X systems:

make MALLOC=jemalloc

3.安装
默认安装至 /usr/local/bin

make install

指定安装路径：

make PREFIX=/some/other/directory install

使用install_server.sh安装，交互式问答，通过/etc/init.d/redis_<portnumber> 启动关闭

cd utils
./install_server.sh

如果报错：
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!
注释相关代码即可

#bail if this system is managed by systemd
#_pid_1_exe="$(readlink -f /proc/1/exe)"
#if [ "${_pid_1_exe##*/}" = systemd ]
#then
#       echo "This systems seems to use systemd."
#       echo "Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!"
#       exit 1
#fi
#unset _pid_1_exe

通过上述操作，会生成一个/etc/init.d/redis_6379，可能需要对相关的配置文件和该命令进行修改。
