Linux installation Redis implementation process and error solution

I installed redis today and some errors occurred that had not occurred before. I will record them here.

1. Install redis and errors

First download redis, the official download address page: https://redis.io/download

We choose the stable version 6.0.1 here

The normal installation steps are as follows:

[root@localhost ~]# yum install gcc
[root@localhost ~]# cd /usr/local
[root@localhost local]# wget http://download.redis.io/releases/redis-6.0.1.tar.gz
[root@localhost local]# tar -xvf redis-6.0.1.tar.gz
[root@localhost local]# cd /usr/local/redis-6.0.1/
[root@localhost redis-6.0.1]# make PREFIX=/usr/local/redis install

The following error is reported here

make[1]: *** [server.o] Error 1
make[1]: Leaving directory "/usr/redis-6.0.1/src"
make: *** [all] Error 2

server.c:2402:11: error: 'struct redisServer' has no member named 'assert_file'

server.assert_line = 0;

server.bug_report_start = 0;

server.watchdog_period = 0;

if (somaxconn > 0 && somaxconn < server.tcp_backlog) {
^
server.c:2575:171: error: 'struct redisServer' has no member named 'tcp_backlog'
serverLog(LL_WARNING,"WARNING: The TCP backlog setting of %d cannot be enforced because /proc/sys/net /core/somaxconn is set to the lower value of %d.", server.tcp_backlog, somaxconn);

Solution: Upgrade the gcc version

[root@localhost redis-6.0.1]# gcc -v # View gcc version
[root@localhost redis-6.0.1]# yum -y install centos-release-scl # Upgrade to version 9.1
[root@localhost redis-6.0.1]# yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
[root@localhost redis-6.0.1]# scl enable devtoolset-9 bash
The above is for temporary use. If you want to use gcc 9.1 for a long time:
[root@localhost redis-6.0.1]# echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile

Then compile:

[root@mmjredis redis-6.0.1]# make PREFIX=/usr/local/redis install

If the installation is successful, the following message will appear: Hint: It's a good idea to run 'make test' 😉

Let's execute make test to test it.

The following error occurred:

[root@localhost redis-6.0.1]# make test
cd src && make test
make[1]: Enter directory "/usr/redis-6.0.1/src"
CC Makefile.dep
make[1]: Leaving directory "/usr/redis-6.0.1/src"
make[1]: Enter directory "/usr/redis-6.0.1/src"
You need tcl 8.5 or newer in order to run the Redis test
make[1]: *** [test] Error 1
make[1]: Leaving directory "/usr/redis-6.0.1/src"
make: *** [test] Error 2

Solution:

[root@localhost redis-6.0.1]# yum install tcl[root@localhost redis-6.0.1]# make test

The test succeeded as follows:

Run redis first and try it:

[root@localhost redis-6.0.1]# /usr/local/redis-6.0.1/src/redis-server /usr/local/redis-6.0.1/redis.conf
32101:C 13 May 2020 17:01:48.248 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

2. Background startup

Simple modification of background startup

[root@localhost redis-6.0.1]# vim redis.conf

Change daemonize no to daemonize yes

Run it again

[root@localhost redis-6.0.1]# /usr/redis-6.0.1/src/redis-server /usr/redis-6.0.1/redis.conf
30385:C 13 May 2020 16:57:58.918 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
30385:C 13 May 2020 16:57:58.918 # Redis version=6.0.1, bits=64, commit=00000000, modified=0, pid=30385, just started
30385:C 13 May 2020 16:57:58.918 # Configuration loaded

The background operation is successful, let's check it and terminate the program

[root@localhost redis-6.0.1]# ps -aux|grep redis| grep -v grep
root 29836 0.0 0.0 162416 7912 ? Ssl 16:56 0:00 /usr/redis-6.0.1/src/redis-server 127.0.0.1:6379
[root@localhost redis-6.0.1]# kill -9 29836

What we use here is to start redis with background systemctl

First, add redis to the service service

vim /lib/systemd/system/redis.service

Write

[Unit]
Description=redis
After=network.target

[Service]
Type=forking
PIDFile=/var/run/redis_6379.pid
ExecStart=/usr/local/redis-6.0.1/src/redis-server /usr/local/redis-6.0.1/etc/redis.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

Note the path problem, and the path of PIDFile corresponds to the PIDFile in redis-6.0.1/src/redis-server

wq save and exit

Then run the following

[root@localhost redis-6.0.1]# systemctl enable redis.service # Add to boot

[root@localhost redis-6.0.1]# systemctl is-enabled redis.service # Check whether the boot is successful
enabled

[root@localhost redis-6.0.1]# systemctl start redis #Start redis service

[root@localhost redis-6.0.1]# systemctl status redis //View the running status of redis

If there is a problem with startup, you can view the log and fix it through systemctl status redis

As shown in the figure, it has been successfully started
