安装mysql

vim /etc/my.cnf

配置文件如下

[mysqld]
bind-address=0.0.0.0
port=3306 # mysql端口号
user=root
basedir=/usr/local/app/mysql # mysql安装目录
datadir=/usr/local/app/mysql/data # 数据存放目录
socket=/tmp/mysql.sock
log-error=/usr/local/app/mysql/log/mysqld.log

--初始化mysql
mysqld --defaults-file=/etc/my.cnf --user=root --basedir=/usr/local/app/mysql --datadir=/usr/local/app/mysql/data/ --initialize

作为服务
cp /usr/local/app/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql

启动mysql服务
service mysql start

修改密码
ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY '123456';

设置远程访问
use mysql;
update user set host = '%' where user = 'root';
FLUSH PRIVILEGES;

设置开机自动重启

添加服务

chkconfig --add mysql

查看服务列表（3、4、5状态为开或者为 on 则表示成功）

chkconfig --list

如果是 关或者 off 则执行一下

chkconfig --level 345 mysql on

jdk配置环境变量
export JAVA_HOME=/usr/local/app/jdk
export PATH=$JAVA_HOME/bin:$PATH

安装redis
wget https://download.redis.io/redis-stable.tar.gz
tar -xzvf redis-stable.tar.gz
cd redis-stable
make
报错1：执行make命令，提示no python3 in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
操作系统没有python3，需要执行 yum install python3命令
报错2：执行make命令，提示 cc: 未找到命令，表示当前环境没有gcc,需要执行 yum install gcc命令
报错3：致命错误：jemalloc/jemalloc.h：没有那个文件或目录
解决方法 make MALLOC=libc

cd /usr/local/app/redis-stable/utils
cp redis_init_script /etc/init.d/
vi /etc/init.d/redis_init_script

修改对应的
REDISPORT=6379
EXEC=/usr/local/app/redis-stable/src/redis-server
CLIEXEC=/usr/local/app/redis-stable/src/redis-cli
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/usr/local/app/redis-stable/redis.conf"

启动脚本
./redis_init_script start
chkconfig redis_init_script on
service redis_init_script start
