saltstack自动化运维系列12配置管理安装redis-3.2.8

一、准备redis自动化配置的文件(即安装一遍redis，然后获取相关文件和配置在salt中执行上线)

1.源码安装redis3.2.8并注册为系统服务

安装依赖
yum install -y tcl

1、下载安装包redis-3.2.8.tar.gz

# cd /usr/local/src# wget http://download.redis.io/releases/redis-3.2.8.tar.gz

2、解压及安装

[root@node2 src]# tar zxf redis-3.2.8.tar.gz[root@node2 src]# cd redis-3.2.8/src/[root@node2 redis-3.2.8]# make PREFIX=/usr/local/redis install #指定安装路径

3、创建配置文档，修改配置

创建配置文档路径

# mkdir /etc/redis[root@node2 src]# cp ../redis.conf /etc/redis/redis_6350.conf

以下几个参数常用到

daemonize yes # 后台运行bind 127.0.0.1 # 绑定ip，需要外网访问时将其注释掉protected-mode yes # 保护模式，默认是开启的，需要其他客户端链接时，改为no关闭requirepass redispass # 其他客户端链接时的密码appendonly yes # 每次更新后记录日志pidfile /var/run/redis_6350.pid # 如果不是默认的6379端口需要修改该行

4、注册系统服务，开机自启

创建启动脚本

# cp ../utils/redis_init_script /etc/rc.d/init.d/redis3

修改redis启动脚本，要修改的地方有

添加 chkconfig 注释redis-server 、redis-cli 、pidfile、redis.conf路径如果需要配置密码，还要在停止命令增加参数 -a 指定密码

[root@node2 src]# cat /etc/init.d/redis3 #!/bin/sh# chkconfig:   2345 90 10# Simple Redis init.d script conceived to work on Linux systems# as it does use of the /proc filesystem.REDISPORT=6350EXEC=/usr/local/redis/bin/redis-serverCLIEXEC=/usr/local/redis/bin/redis-cliPIDFILE=/var/run/redis_${REDISPORT}.pidCONF="/etc/redis/redis_${REDISPORT}.conf"usage(){    echo "usage: $0 [start|stop|status|restart]"}redis_start(){if [ -f $PIDFILE ]    then            echo "$PIDFILE exists, process is already running or crashed"    else            echo "Starting Redis server..."            $EXEC $CONFfi}redis_stop(){    if [ ! -f $PIDFILE ]    then            echo "$PIDFILE does not exist, process is not running"    else            PID=$(cat $PIDFILE)            echo "Stopping ..."            $CLIEXEC -p $REDISPORT -a redispass shutdown            while [ -x /proc/${PID} ]            do                echo "Waiting for Redis to shutdown ..."                sleep 1            done            echo "Redis stopped"    fi}redis_restart(){    redis_stop    sleep 1    redis_start}redis_status(){    ps -ef|grep redis|grep -v grep|grep -v status}main(){    case "$1" in        start)            redis_start;;        stop)            redis_stop;;        status)            redis_status;;         restart)            redis_restart;;        *)            usage;    esac}main $1

保存后执行注册成系统服务：

chkconfig --add redis3
chkconfig redis3 on

完成后，可以使用 service redis3 start|stop 启动关闭redis服务

5、添加环境变量:

vim /etc/profile

在最后添加:

PATH=$PATH:/usr/local/redis/binexport PATH

# 使配置生效
source /etc/profile

# service redis3 start[root@node2 src]# ps -ef|grep redisroot     20818     1  0 09:57 ?        00:00:00 /usr/local/redis/bin/redis-server 127.0.0.1:6350root     20827 14125  0 09:58 pts/0    00:00:00 grep --color=auto redis

用redis-cli 链接，set，get正常

[root@node2 src]# redis-cli -p 6350 -a redispass127.0.0.1:6350> set name 2OK127.0.0.1:6350> get name"2"127.0.0.1:6350> set jack 18OK127.0.0.1:6350> get jack"18"127.0.0.1:6350> quit

二、salt相关的配置处理

# mkdir -p /srv/salt/prod/pkg /srv/salt/prod/redis /srv/salt/prod/redis/files # cd /srv/salt/prod/pkg

1.初始化nginx相关配置文件
①下载redis-3.2.8.tar.gz上传到/srv/salt/prod/redis/files目录
②配置文件

[root@test7_chat_api_im files]# grep '^[a-Z]' redis_6350.conf bind 127.0.0.1protected-mode yesport 6350tcp-backlog 511timeout 0tcp-keepalive 300daemonize yessupervised nopidfile /var/run/redis_6350.pidloglevel noticelogfile ""databases 16save 900 1save 300 10save 60 10000stop-writes-on-bgsave-error yesrdbcompression yesrdbchecksum yesdbfilename dump.rdbdir ./slave-serve-stale-data yesslave-read-only yesrepl-diskless-sync norepl-diskless-sync-delay 5repl-disable-tcp-nodelay noslave-priority 100requirepass redispassappendonly yesappendfilename "appendonly.aof"appendfsync everysecno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mbaof-load-truncated yeslua-time-limit 5000slowlog-log-slower-than 10000slowlog-max-len 128latency-monitor-threshold 0notify-keyspace-events ""hash-max-ziplist-entries 512hash-max-ziplist-value 64list-max-ziplist-size -2list-compress-depth 0set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64hll-sparse-max-bytes 3000activerehashing yesclient-output-buffer-limit normal 0 0 0client-output-buffer-limit slave 256mb 64mb 60client-output-buffer-limit pubsub 32mb 8mb 60hz 10aof-rewrite-incremental-fsync yes

③服务管理脚本

[root@test7_chat_api_im files]# cat redis3 #!/bin/sh# chkconfig:   2345 90 10# Simple Redis init.d script conceived to work on Linux systems# as it does use of the /proc filesystem.REDISPORT=6350EXEC=/usr/local/redis/bin/redis-serverCLIEXEC=/usr/local/redis/bin/redis-cliPIDFILE=/var/run/redis_${REDISPORT}.pidCONF="/etc/redis/redis_${REDISPORT}.conf"case "$1" in    start)        if [ -f $PIDFILE ]        then                echo "$PIDFILE exists, process is already running or crashed"        else                echo "Starting Redis server..."                $EXEC $CONF        fi        ;;    stop)        if [ ! -f $PIDFILE ]        then                echo "$PIDFILE does not exist, process is not running"        else                PID=$(cat $PIDFILE)                echo "Stopping ..."                $CLIEXEC -p $REDISPORT -a redispass shutdown                while [ -x /proc/${PID} ]                do                    echo "Waiting for Redis to shutdown ..."                    sleep 1                done                echo "Redis stopped"        fi        ;;    *)        echo "Please use start or stop as first argument"        ;;esac

2.编写依赖包安装
vim /srv/salt/prod/pkg/pkg-init.sls

pkg-init:  pkg.installed:    - names:      - gcc      - gcc-c++      - glibc      - make      - autoconf      - openssl      - openssl-devel      - pcre      - pcre-devel      - glib      - glib-devel      - tcl

3.用户添加模块

# mkdir /srv/salt/prod/user# vim /srv/salt/prod/user/redis.sls redis-user-group:  group.present:    - name: redis    - gid: 6350  user.present:    - name: redis    - fullname: redis    - shell: /sbin/nologin    - uid: 6350    - gid: 6350

4.编写nginx状态模块

# cd /srv/salt/prod/redisvim /srv/salt/prod/redis/install.slsinclude:  - pkg.pkg-init  - user.redisredis-source-install:  file.managed:    - name: /usr/local/src/redis-3.2.8.tar.gz    - source: salt://redis/files/redis-3.2.8.tar.gz    - user: root    - group: root    - mode: 755  cmd.run:    - name: cd /usr/local/src && tar zxf redis-3.2.8.tar.gz && cd cd redis-3.2.8/src/ && make PREFIX=/usr/local/redis install && chown -R redis:redis /usr/local/redis && mkdir /etc/redis    - unless: test -d /usr/local/redis    - require:      - user: redis-user-group      - file: redis-source-install      - pkg: pkg-init

服务模块

# vim /srv/salt/prod/redis/service.sls include:  - redis.installredis-init:  file.managed:    - name: /etc/init.d/redis3    - source: salt://redis/files/redis3    - mode: 755    - user: root    - group: root    - require:      - cmd: redis-source-install  cmd.run:    - name: chkconfig --add redis3    - unless: chkconfig --list | grep redis    - require:      - file: redis-init/etc/redis/redis_6350.conf:  cmd.run:    - name: mkdir /etc/redis  file.managed:    - source: salt://redis/files/redis_6350.conf    - user: redis    - group: redis    - mode: 644 redis-service:  service.running:    - name: redis3    - enable: True    - restart: True    - require:      - cmd: redis-init    - watch:      - file: /etc/redis/redis_6350.conf

执行配置测试，没有问题再安装，至此salt安装redis服务已完毕：

# 先测试先处理一些简单的错误

salt 'test4_haili_dev' state.sls redis.service env=prod test=Truesalt 'test4_haili_dev' state.sls redis.service env=prod
