centos7下的redis 6.2.6 編譯安裝

1、升級編譯環境

# yum install centos-release-scl scl-utils-build

# yum install -y devtoolset-8-toolchain

# scl enable devtoolset-8 bash

# echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile

 

2、下載軟件包

# wget https://download.redis.io/releases/redis-6.2.6.tar.gz

# tar xzf redis-6.2.6.tar.gz

# cd redis-6.2.6

 

3、開始編譯

# make           //如果出錯運行make distclean

# make install PREFIX=/usr/local/redis  //默認安裝在/usr/local/bin下

# cp  /root/soft/redis.conf /etc

# vim /etc/redis.conf

75 bind 127.0.0.1 192.168.10.84        //綁定本地主機的ip
98 port 6379
257 daemonize yes
289 pidfile /var/run/redis_6379.pid 302 logfile "/var/log/redis.log" 327 databases 16 431 dbfilename dump.rdb 483 requirepass centos //設置redis登錄密碼為centos


4、編輯redis的啟動文件

# vim /usr/lib/systemd/system/redis.service

[Unit]
Description=Redis persistent key-value database
After=network.target
After=network-online.target
Wants=network-online.target

[Service]
Type=forking
PIDFile=/var/run/redis_6379.pid
ExecStart=/usr/local/bin/redis-server /etc/redis.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID

[Install]
WantedBy=multi-user.target

 

5、優化redis

# vim /etc/sysctl.conf

vm.nr_hugepages=2000              // 內存優化選項
vm.overcommit_memory=1         //表示內存將檢查是否有足夠的可用內存供應用進程使用，如果有，允許申請
net.core.somaxconn=1024         //增大tcp連接的數量，默認128太小

# sysctl -p

 

6、解決透明大頁，可能導致redis延遲和內存使用問題

# vim  /etc/rc.local

echo never > /sys/kernel/mm/transparent_hugepage/enabled

# chmod +x /etc/rc.d/rc.local

# systemctl enable redis

# systemctl start redis

 

7、redis防火牆設置

# firewall-cmd --permanent --zone=public --add-port=6379/tcp

# firewall-cmd --reload

 

8、redis常用命令

關閉命令：

# redis-cli shutdown
# redis-cli -p 6379 shutdown

開啟命令：

# redis /etc/redis.conf
