99-redis_install
0. 停启
- linux
service redis_6379 start/stop/restart/status
- mac
sudo sh ~/shell/redis/redis_6379.sh
1. download
# 源码下载
yum install wget https://download.redis.io/releases/redis-6.2.6.tar.gz
2. make
- make编译后，src下便出现可执行程序，即可直接启动

- 读
README.md make命令为linux、mac自带的编译命令。具体怎样编译依赖Makefile文件- nginx源码是没有Makefile文件，需要
configuration命令生成
- nginx源码是没有Makefile文件，需要
1. gcc
# 安装c环境
yum install gcc
# 第一次安装，一些条件不具备，可是已经make了一部分
# 清除make，把不具备的条件都具备下，再make
make distclean
3. linux_install
1. make install
- 通过
make install。相当于创建redis-server快捷方式
[root@hecs-168322 redis-6.2.6]# make install PREFIX=/usr/local/redis
cd src && make install
make[1]: Entering directory `/root/soft/redis-6.2.6/src'
CC Makefile.dep
make[1]: Leaving directory `/root/soft/redis-6.2.6/src'
make[1]: Entering directory `/root/soft/redis-6.2.6/src'
Hint: It's a good idea to run 'make test' ;)
INSTALL redis-server
INSTALL redis-benchmark
INSTALL redis-cli

2. 环境变量
# 将下面的内容加到文件尾
vi /etc/profile
# 重启profile
source /etc/profile
# 验证环境变量的添加情况
echo $PATH
# profile文件末尾添加
# REDIS_HOME目录位置即install目录
export REDIS_HOME=/usr/local/redis
export PATH=$REDIS_HOME/bin:$PATH
# 新开窗口。验证环境变量的添加情况
[root@hecs-168322 ~]# echo $PATH

3. install_server.sh
- 一个物理机可以有多个redis实例（进程），通过port区分。可执行程序就一份在目录，但是内存中的多个实例需要各自的配置文件，持久化目录等资源
- 执行./install_server.sh问题

4. mac_install
1. 环境变量
- 解决找不到默认配置文件问题
- Mac下添加环境变量（一劳永逸）
- root账号
# 修改完了，强制保存：wq!。立即生效
# 'readonly' option is set (add ! to override)
vim /etc/zshrc
# zshrc文件最后加上

3. install_server.sh
# install_server.sh目录
cd /Users/list/soft/redis/redis-6.2.6/utils
- Mac不识别install_server.sh中readlink命令
- Mac上安装Redis遇到问题 Mmmmm... the default config is missing. Did you switch to the utils directory?
- 无法找到默认配置文件
redis.conf在哪儿（其实就在上一层目录里） install_server.sh替换下面内容
#Absolute path to this script
SCRIPT=$(readlink -f $0)
#Absolute path this script is in
SCRIPTPATH=$(dirname $SCRIPT)
#Absolute path this script is in
SCRIPTPATH=$(cd `dirname $0`; pwd)
- unix不支持init.d
- linux会将停启脚本写到
init.d中，达到开机启动目的
- 因此mac没有
redis_6379停启脚本 - 注释掉下面两部分
#copy to /etc/init.d
cp $TMP_FILE $INIT_SCRIPT_DEST && \
chmod +x $INIT_SCRIPT_DEST || die "Could not copy redis init script to $INIT_SCRIPT_DEST"
echo "Copied $TMP_FILE => $INIT_SCRIPT_DEST"
/etc/init.d/redis_$REDIS_PORT start || die "Failed starting service..."
