Centos下安装Redis

CentOS安装Redis5.0

官网下载源码包，解压， 根据redeme中的提示按照步骤安装。注意，make是linux系统自带的c编译器，记得安装gcc：

yum install gcc

安装步骤：

# 编译，make命令会去当前路径寻找Makefile文件，执行编译过程
make
make install
# 指定位置安装
make install PREFIX=/opt/redis/

CentOS7安装Redis6.0

# 安装依赖
yum -y install gcc centos-release-scl cmake wget tcl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
# 解决gcc版本低的问题-临时
scl enable devtoolset-9 bash
# 解决gcc版本低的问题-永久
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
# 编译
make
# 安装， 默认安装到/usr/local/bin 目录下
make install
# 指定位置安装
make install PREFIX=/root/redis6

./utils/install_server.sh安装redis服务

在源码包下，有一个快速安装redis服务的脚本： ./utils/install_server.sh，执行此脚本，会提示输入相应的参数去安装redis服务，或者指定相应的参数去直接安装redis服务：

sudo REDIS_PORT=6379 \
               REDIS_CONFIG_FILE=/etc/redis/6379.conf \
               REDIS_LOG_FILE=/var/log/redis_6379.log \
               REDIS_DATA_DIR=/var/lib/redis/6379 \
               REDIS_EXECUTABLE=`command -v redis-server` ./utils/install_server.sh

在redis6版本中，可能会出现如下错误：

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!

解决方案：修改脚本 vi ./install_server.sh ，将下面代码注释代码

#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
