安装mysql数据库
# 下载mysql源安装包 wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm # 安装mysql源 yum localinstall mysql57-community-release-el7-8.noarch.rpm -y # 检查mysql源是否安装成功 yum repolist enabled | grep "mysql.*-community.*" # 安装MySQL yum install mysql-community-server -y # 3、启动MySQL服务 systemctl start mysqld # 查看MySQL的启动状态 systemctl status mysqld #4、开机启动 systemctl enable mysqld systemctl daemon-reload # 5、修改root本地登录密码 # mysql安装完成之后，在/var/log/mysqld.log文件中给root生成了一个默认密码。通过下面的方式找到root默认密码，然后登录mysql进行修改： grep 'temporary password' /var/log/mysqld.log mysql -uroot -p # mysql5.7默认安装了密码安全检查插件(validate_password)，默认密码检查策略要求密码必须包含：大小写字母、数字和特殊符号， # 并且长度不能少于8位。否则会提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements错误 # 如果不需要密码策略，添加my.cnf文件中添加如下配置禁用即可： # 配置默认编码为utf8 # 关闭客户端dns反解 echo -e "validate_password = off\ncharacter_set_server=utf8\ninit_connect='SET NAMES utf8'\nskip-name-resolve\n" >> /etc/my.cnf systemctl restart mysqld mysql -uroot -p ## 授权 alter user 'root'@'localhost' identified by '123123'; grant all privileges on *.* to root@'%' identified by '123123' with grant option; flush privileges;
安装Redis
yum 安装redis 3.2 yum -y install redis
文档 https://redis.io/download 编译安装redis-6.2.1 yum install -y gcc gcc-c++ tcl wget -O /opt/tgzs/redis-6.2.1.tar.gz https://download.redis.io/releases/redis-6.2.1.tar.gz cd /opt/tgzs/ #解压redis tar xf redis-6.2.1.tar.gz #进入解压后的目录 cd redis-6.2.1 #分配器allocator，如果有MALLOC 这个 环境变量， 会有用这个环境变量的 去建立Redis。 #而且libc 并不是默认的分配器， 默认的是 jemalloc, 因为 jemalloc 被证明 有更少的 fragmentation problems 比libc。 #但是如果你又没有jemalloc而只有 libc 当然 make 出错。 所以加这么一个参数,运行如下命令： make MALLOC=libc -j 20 #编译 # make -j 20 #创建redis安装目录，主要用于存放redis所需bin文件 mkdir -p /usr/local/redis #安装redis并指定安装目录 make PREFIX=/usr/local/redis/ install # 设置path export PATH=$PATH:/usr/local/redis/bin #复制默认配置文件到/etc egrep -v "^$|#" redis.conf > redis_sample.conf #修改配置文件监听IP为0.0.0.0，否则只能本地登录 sed -i s/bind\ 127.0.0.1/bind\ 0.0.0.0/g redis_sample.conf #修改运行方式为后台运行 sed -i s/daemonize\ no/daemonize\ yes/g redis_sample.conf /bin/cp -f redis_sample.conf /etc/redis_6379.conf /bin/cp -f redis_sample.conf /etc/redis_6479.conf #设置日志文件路径 sed -i s@logfile\ \"\"@logfile\ \"/opt/logs/redis_6379.log\"@g /etc/redis_6379.conf sed -i s@logfile\ \"\"@logfile\ \"/opt/logs/redis_6479.log\"@g /etc/redis_6479.conf #设置数据目录 sed -i s@dir\ \./@dir\ /var/lib/redis_6379@g /etc/redis_6379.conf sed -i s@dir\ \./@dir\ /var/lib/redis_6479@g /etc/redis_6479.conf # 修改port sed -i 's/port 6379/port 6379/g' /etc/redis_6379.conf sed -i 's/port 6379/port 6479/g' /etc/redis_6479.conf mkdir /var/lib/redis_6379 mkdir /var/lib/redis_6479 mkdir /opt/logs cat <<EOF > /etc/systemd/system/redis_6379.service [Unit] Description=The redis-server Process Manager After=syslog.target network.target [Service] Type=forking ExecStart=/usr/local/redis/bin/redis-server /etc/redis_6379.conf #ExecStop=/usr/local/redis/bin/redis-shutdown [Install] WantedBy=multi-user.target EOF cat <<EOF > /etc/systemd/system/redis_6479.service [Unit] Description=The redis-server Process Manager After=syslog.target network.target [Service] Type=forking ExecStart=/usr/local/redis/bin/redis-server /etc/redis_6479.conf #ExecStop=/usr/local/redis/bin/redis-shutdown [Install] WantedBy=multi-user.target EOF systemctl daemon-reload #设置redis开机自启 system enable redis_6379 system enable redis_6479 #启动redis systemctl restart redis_6379 systemctl restart redis_6479 #查看redis状态 systemctl status redis_6379 systemctl status redis_6479
