前段时间安装好的redis,今天用脚本安装的时候突然出现版本异常的问题,所以更新一篇为大家提供参考
本次安装在CentOS6.5,采用的redis-3.2.10,最新的redis-4.0.1安装同样适用,不过由于4.0.1版本的redis改动较大,大家自己选择即可。,
1.基础环境配置,上传安装包
useradd redis -s /sbin/nologin -M mkdir -p /server/tools/ cd /server/tools/
2.安装redis,配置开机自启动
# 解压,编译安装
tar -zxf redis-3.2.10.tar.gz cd redis-3.2.10 make PREFIX=/usr/local/redis make PREFIX=/usr/local/redis install
# 配置环境变量,便于命令工具的调用访问
export PATH=/usr/local/redis/bin/:$PATH echo ‘export PATH=/usr/local/redis/bin:$PATH‘ >> /etc/profile echo $PATH
# 手动创建标准目录结构,操作规范化
mkdir -p /usr/local/redis/{conf,data,logs} /bin/cp /server/tools/redis-3.2.10/redis.conf /usr/local/redis/conf/redis.conf.ori
tree /usr/local/redis
# 创建修改配置文件
cd /usr/local/redis/conf egrep -v "^#|^$" redis.conf.ori>redis.conf
cat redis.conf
# 默认生效的配置如下:
bind 127.0.0.1 protected-mode yes port 6379 tcp-backlog 511 timeout 0 tcp-keepalive 300 daemonize no supervised no pidfile /var/run/redis_6379.pid loglevel notice logfile "" databases 16 save 900 1 save 300 10 save 60 10000 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dbfilename dump.rdb dir ./ slave-serve-stale-data yes slave-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no slave-priority 100 appendonly no appendfilename "appendonly.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 latency-monitor-threshold 0 notify-keyspace-events "" hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-size -2 list-compress-depth 0 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 hll-sparse-max-bytes 3000 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 aof-rewrite-incremental-fsync yes
# 修改配置文件
vim redis.conf
# 确认以下必要的配置,修改完毕后的配置文件可以作为模板,用于创建新的redis实例
bind 0.0.0.0
port 6379 daemonize yes pidfile /usr/local/redis/logs/redis.pid logfile /usr/local/redis/logs/redis.log dir /usr/local/redis/data dbfilename redis.rdb
# 内核参数调优(临时)
echo never > /sys/kernel/mm/transparent_hugepage/enabled echo 511 > /proc/sys/net/core/somaxconn cat /sys/kernel/mm/transparent_hugepage/enabled cat /proc/sys/net/core/somaxconn echo "vm.overcommit_memory = 1" >>/etc/sysctl.conf sysctl -p
# 启动redis,并查看redis启动状态
/usr/local/redis/bin/redis-server /usr/local/redis/conf/redis.conf ps -ef |grep redis netstat -anptl |grep redis
[root@redis-server conf]# cat /usr/local/redis/logs/redis.log 6003:M 04 Sep 21:10:39.252 * Increased maximum number of open files to 10032 (it was originally set to 1024). _._ _.-``__ ‘‘-._ _.-`` `. `_. ‘‘-._ Redis 3.2.10 (00000000/0) 64 bit .-`` .-```. ```\/ _.,_ ‘‘-._ ( ‘ , .-` | `, ) Running in standalone mode |`-._`-...-` __...-.``-._|‘` _.-‘| Port: 6379 | `-._ `._ / _.-‘ | PID: 6003 `-._ `-._ `-./ _.-‘ _.-‘ |`-._`-._ `-.__.-‘ _.-‘_.-‘| | `-._`-._ _.-‘_.-‘ | http://redis.io `-._ `-._`-.__.-‘_.-‘ _.-‘ |`-._`-._ `-.__.-‘ _.-‘_.-‘| | `-._`-._ _.-‘_.-‘ | `-._ `-._`-.__.-‘_.-‘ _.-‘ `-._ `-.__.-‘ _.-‘ `-._ _.-‘ `-.__.-‘ 6003:M 04 Sep 21:10:39.255 # Server started, Redis version 3.2.10 6003:M 04 Sep 21:10:39.255 * The server is now ready to accept connections on port 6379
# 连接redis,进行测试
[root@redis-server conf]# /usr/local/redis/bin/redis-cli -p 6379 127.0.0.1:6379> set a 1 OK 127.0.0.1:6379> set b 2 OK 127.0.0.1:6379> set c 3 OK 127.0.0.1:6379> get a "1" 127.0.0.1:6379> get b "2" 127.0.0.1:6379> get c "3" 127.0.0.1:6379> exit [root@redis-server conf]#
# 安全关闭redis-server
/usr/local/redis/bin/redis-cli shutdown
# 另外,需要设置一下内核参数保证下次重启不会出错
echo " ">> /etc/rc.local echo "# redis by zhaoshuai in $(date +%F)" >> /etc/rc.local echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >> /etc/rc.local echo "echo 511 > /proc/sys/net/core/somaxconn" >>/etc/rc.local tail -4 /etc/rc.local
# 至此,redis-server就安装完成了。
3.创建新的redis实例(端口)
mkdir -p /usr/loca/redis/6380 cd /usr/local/redis/conf cp redis.conf /usr/loca/redis/6380/6380.conf
cd /usr/local/redis/6380/
# 编辑配置文件,
vim 6380.conf
# 修改为以下内容:
bind 0.0.0.0 daemonize yes pidfile /usr/local/redis/6380/pid-6380.pid logfile /usr/local/redis/6380/log-6380.log dir /usr/local/redis/6380 dbfilename 6380.rdb
......
# 启动redis新实例,如果需要可以设置开机自启动
[root@redis-server 6380]# /usr/local/redis/bin/redis-server /usr/local/redis/6380/6380.conf
[root@redis-server 6380]# echo "/usr/local/redis/bin/redis-server /usr/local/redis/6380/6380.conf" >>/etc/rc.local
4.另附一个redis启动管理脚本,方便大家学习使用
#!/bin/sh # # chkconfig: 2345 85 15 # description: this script can manager the redis-server daemon # Redis is a persistent key-value database # exec: /usr/local/redis/bin/redis-server # config: /usr/local/redis/conf/redis.conf # pidfile: /usr/local/redis/logs/redis.pid # datafile: /usr/local/redis/data/redis.rdb redis="/usr/local/redis/bin/redis-server" REDIS_CONF_FILE="/usr/local/redis/conf/redis.conf" prog=$(basename $redis) lockfile=/var/lock/subsys/redis # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ "$NETWORKING" = "no" ] && exit 0 start() { [ -x $redis ] || exit 5 [ -f $REDIS_CONF_FILE ] || exit 6 echo -n $"Starting $prog: " daemon $redis $REDIS_CONF_FILE retval=$? echo [ $retval -eq 0 ] && touch $lockfile return $retval } stop() { echo -n $"Stopping $prog: " killproc $prog -QUIT retval=$? echo [ $retval -eq 0 ] && rm -f $lockfile return $retval } restart() { stop start } reload() { echo -n $"Reloading $prog: " killproc $redis -HUP RETVAL=$? echo } rh_status() { status $prog } rh_status_q() { rh_status >/dev/null 2>&1 } case "$1" in start) rh_status_q && exit 0 $1 ;; stop) rh_status_q || exit 0 $1 ;; restart) $1 ;; reload) rh_status_q || exit 7 $1 ;; status) rh_status ;; *) echo $"Usage: $0 {start|stop|restart|reload|status}" exit 2 esac
# 完毕,呵呵呵
