Redis服务部署

服务器环境

相关目录规划

redis_server: /etc/init.d/redis_6379

redis_config: /etc/redis/6379.conf

redis_data: /data/Redisdata 用于存放Redis数据库文件

安装过程

# 基本步骤如下
[root@BasicService ~]# yum install gcc 
[root@BasicService ~]# mkdir Packages && cd Packages
[root@BasicService ~]# wget http://download.redis.io/releases/redis-6.0.16.tar.gz
[root@BasicService ~]# tar zxvf redis-6.0.16.tar.gz && cd redis-6.0.16
[root@BasicService ~]# make
[root@BasicService ~]# make install PREFIX=/usr/local/redis-6.0.16
# 详情可阅读redis-6.0.16/README.md
[root@BasicService ~]# cd utils
[root@BasicService ~]# ./install_server.sh

安装过程中可能出现的错误

[root@BasicService ~]# make
server.c: In function ‘main’:
server.c:5011:11: error: ‘struct redisServer’ has no member named ‘sentinel_mode’
     server.sentinel_mode = checkForSentinelMode(argc,argv);
           ^
server.c:5028:15: error: ‘struct redisServer’ has no member named ‘sentinel_mode’
     if (server.sentinel_mode) {
# 需要升级GCC版本
[root@BasicService ~]# yum -y install centos-release-scl
[root@BasicService ~]# yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
[root@BasicService ~]# scl enable devtoolset-9 bash
# 注意：scl命令启用只是临时的，退出xshell或者重启就会恢复到原来的gcc版本。
# 如果要长期生效的话，执行如下：
[root@BasicService ~]# echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
# 清理上次make失败的文件和目录，再次知执行make
[root@BasicService ~]# make distclean
[root@BasicService ~]# make
[root@BasicService ~]# make install PREFIX=/usr/local/redis-6.0.16

将Redis添加到系统服务

# 配置redis的环境变量
[root@BasicService ~]# vi /etc/profile
# 增加如下内容
export REDIS_HOME=/usr/local/redis-6.0.16
export PATH=$PATH:$REDIS_HOME/bin
[root@BasicService ~]# source /etc/profile

# 执行注册服务脚本
[root@BasicService ~]# cd utils
# 首先注释如下信息，否则执行过程中报错
[root@BasicService ~]# vim install_server.sh
#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
[root@BasicService ~]# ./install_server.sh

# 为了快速关闭redis服务，可以通过修改服务stop模块，执行kill
[root@BasicService ~]# vim /etc/init.d/redis_6379
    stop)
        if [ ! -f $PIDFILE ]
        then
            echo "$PIDFILE does not exist, process is not running"
        else
            PID=$(cat $PIDFILE)
            echo "Stopping ..."
            /usr/bin/kill -9 `cat $PIDFILE`
            #$CLIEXEC -p $REDISPORT shutdown
		...

# 通过systemctl管理redis服务
[root@BasicService ~]# systemctl status redis_6379
[root@BasicService ~]# systemctl start redis_6379
[root@BasicService ~]# systemctl stop redis_6379

redis配置文件

[root@BasicService ~]# vim /etc/redis/6379.conf
# 开启守护进程
daemonize yes
# 去除bing的ip，否则无法使用远程连接
# bind 127.0.0.1
# 关闭保护模式，将protected-mode的yes改为no，也是开启远程连接。
protected-mode no
