四、启动Redis

--------------------

# 一、Redis官网 #

[https://redis.io/download][https_redis.io_download]

本文使用的是当下最新的稳定版本V6.0.9

# 二、安装Redis #

## 1、解压 ##

**tar -zxf redis-6.0.9.tar.gz**

## 2、编译源码 ##

**make**

注：make过程可能会报错，错误信息如下

In file included from server.c:30:0:
    server.h:1072:5: error: expected specifier-qualifier-list before ‘_Atomic’
         _Atomic unsigned int lruclock; /* Clock for LRU eviction */
         ^
    server.c: In function ‘serverLogRaw’:
    server.c:1031:31: error: ‘struct redisServer’ has no member named ‘logfile’
         int log_to_stdout = server.logfile[0] == '\0';
                                   ^
    server.c:1034:23: error: ‘struct redisServer’ has no member named ‘verbosity’
         if (level < server.verbosity) return;
                           ^
    server.c:1036:47: error: ‘struct redisServer’ has no member named ‘logfile’
         fp = log_to_stdout ? stdout : fopen(server.logfile,"a");
                                                   ^
    server.c:1049:47: error: ‘struct redisServer’ has no member named ‘timezone’
             nolocks_localtime(&tm,tv.tv_sec,server.timezone,server.daylight_active);
                                                   ^
    ........

错误原因：GCC版本低了，新版的Redis用到了c11，系统默认自带版本是4.8.5

[root@10 redis-6.0.9]# gcc --version
    gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)

解决方法：需要更新gcc到5.4版本以上，安装命令如下

yum groupinstall "Development Tools"

strings /usr/lib64/libstdc++.so.6 | grep GLIBC

cd /usr/local/src/

wget http://ftp.gnu.org/gnu/gcc/gcc-10.2.0/gcc-10.2.0.tar.gz   //速度较慢，使用镜像站：wget http://mirror.hust.edu.cn/gnu/gcc/gcc-10.2.0/gcc-10.2.0.tar.gz

**tar -zxf** gcc-10.2.0.tar.gz

cd gcc-10.2.0

./contrib/download\_prerequisites

./configure -enable-checking=release -enable-languages=c,c++ -disable-multilib

make -j4

ls /usr/local/bin | grep gcc

make install

由于安装过程很慢，另一种升级方式：

yum -y install centos-release-scl  
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils  
scl enable devtoolset-9 bash  
echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile  
gcc -v

## 3、安装 ##

**make install**

[root@10 redis-6.0.9]# cd src/
    [root@10 src]# make install
    
    Hint: It's a good idea to run 'make test' ;)
    
        INSTALL install
        INSTALL install
        INSTALL install
        INSTALL install
        INSTALL install

# 三、部署Redis #

## 1、创建bin和etc文件夹 ##

\[root@10 redis-6.0.9\]\# mkdir etc  
\[root@10 redis-6.0.9\]\# mkdir bin

##    2、移动文件 ##

\[root@10 src\]\# mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-server ../bin/  
\[root@10 src\]\# cd ../bin/  
\[root@10 bin\]\# ls  
mkreleasehdr.sh  redis-check-aof  redis-cli  
redis-benchmark  redis-check-rdb  redis-server  
\[root@10 bin\]\# cd ..  
\[root@10 redis-6.0.9\]\# mv redis.conf etc/  
\[root@10 redis-6.0.9\]\# cd etc  
\[root@10 etc\]\# ls  
redis.conf

# 四、启动Redis #

[root@10 bin]# ./redis-server
