mkdir -p /data

1. 切换到该data目录

cd /data

JDK1.8安装

• JDK下载
• 如果需要用户密码，注册一个即可
• 用winSCP上传到服务器data目录下
• 解压文件

tar -zxvf jdk-8u211-linux-x64.tar.gz

Maven安装

• maven下载

wget http://mirrors.gigenet.com/apache/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz

• 解压maven

tar -zxvf apache-maven-3.6.1-bin.tar.gz

环境变量配置

vi /etc/profile #找到最后一行，插入以下内容 JAVA_HOME=/data/jdk1.8.0_211 MAVEN_HOME=/data/apache-maven-3.6.1 PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$PATH CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar export PATH JAVA_HOME CLASSPATH #wq!保存退出,并更新 source /etc/profile

Nginx下载安装

1. 安装依赖

yum install -y gcc-c pcre pcre-devel zlib zlib-devel openssl openssl-devel

1. 下载nginx

wget http://nginx.org/download/nginx-1.12.2.tar.gz

1. 解压

tar -zxvf nginx-1.12.2.tar.gz

1. 编译安装

cd nginx-1.12.2 ./configure --prefix=/usr/local/nginx --with-http_ssl_module make && make install

1. nginx启动

/usr/local/nginx/sbin/nginx

1. 检查是否成功

打开浏览器访问此机器的 IP，如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功

1. nginx常用命令

#校验Nginx配置文件是否正确 /usr/local/nginx/sbin/nginx -t #开启Nginx /usr/local/nginx/sbin/nginx #重启Nginx /usr/local/nginx/sbin/nginx -s reload #停止Nginx /usr/local/nginx/sbin/nginx -s stop

1. nginx配置

cd /usr/local/nginx/conf #新建自定义配置目录 mkdir conf.d #备份nginx配置 cp nginx.conf nginx.conf.bak vi nginx.conf #在最后一行加入自定义配置目录 include /usr/local/nginx/conf/conf.d/*.conf; #自定义配置 cd conf.d vi sample.conf 内容示例如下： server { # https 配置 listen 443; server_name dev.xueshitang.cn; ssl on; #证书地址 ssl_certificate cert/2450982_dev.xueshitang.cn.pem; ssl_certificate_key cert/2450982_dev.xueshitang.cn.key; ssl_session_timeout 5m; ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; #小程序 location /HtXLqKtu1d.txt { root /usr/local/nginx/html; } error_page 500 502 503 504 /repaire.html; location = /repaire.html { root /usr/local/nginx/html; } location / { proxy_set_header Host $host; proxy_set_header X-Real-Ip $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_pass http://127.0.0.1:8098/; root html; index index.html index.htm; } }

1. 证书放在cert目录下
2. 重启nginx

/usr/local/nginx/sbin/nginx -s reload

mysql安装

1. 查看有没有mysql

yum list installed | grep mysql 如果有，就先全部卸载，命令如下： yum -y remove mysql-community-client.x86_64 rpm -qa | grep -i mysql find / -name mysql rm -rf /var/lib/mysql /usr/share/mysql /usr/lib64/mysql /usr/bin/mysql /etc/logrotate.d/mysql /etc/selinux/targeted/active/modules/100/mysql /var/lib/mysql/mysql

1. 下载mysql的repo源

wget http://repo.mysql.com/mysql80-community-release-el7-3.noarch.rpm

1. 安装mysql80-community-release-el7-3.noarch.rpm包

sudo rpm -ivh mysql80-community-release-el7-3.noarch.rpm yum clean all yum makecache

1. 安装mysql

sudo yum install mysql-server

1. 启动mysql

systemctl start mysqld.service

1. 获取初始密码登录mysql
   mysql在安装后会创建一个root@locahost账户，并且把初始的密码放到了/var/log/mysqld.log文件中；

cat /var/log/mysqld.log | grep password 如果没有密码,则直接 mysql -u root 登录

1. 修改root远程登录

use mysql; update user set host = '%' where user ='root'; FLUSH PRIVILEGES; # navicat连接报错解决 Client does not support authentication protocol requested by server; consider upgrading MySQL client alter user 'root'@'%' identified by 'password' password expire never; alter user 'root'@'%' identified with mysql_native_password by 'passd';//passd是自己新修改的密码。 flush privileges;再次刷新一下权限配置。

阿里云swap分区，解决内存不足的问题

1. 查看swap情况

cat /proc/swaps top free -m

1. 此文件的大小是count的大小乘以bs大小，下面命令的大小是8GB

dd if=/dev/zero of=/swap_file bs=1M count=8192

1. 通过mkswap命令将上面新建出的文件做成swap分

mkswap /swap_file

1. 启用交换分区,并使用命令查看内存占用情况

swapon /swap_file free -m

1. 设置开机自动挂载

vi /etc/fstab /swap_file swap swap defaults 0 0

1. 查看内核参数vm.swappiness中的数值是否为0，如果为0则根据实际需要调整成30或者60

cat /proc/sys/vm/swappiness sysctl -a | grep swappiness sysctl -w vm.swappiness=50

1. 关闭swap分区

swapoff /data/swap swapoff -a >/dev/null

git 安装

1. 查询

rpm -qa|grep git

1. 卸载之前的git

rpm -e --nodeps git

1. 安装

yum install git

redis安装

1. 下载

wget http://download.redis.io/releases/redis-4.0.6.tar.gz

1. 解压

tar -zxvf redis-4.0.6.tar.gz

1. 进入redis目录，编译安装

cd redis-4.0.6 make MALLOC=libc cd src && make install

1. 修改配置

mkdir -p /usr/local/redis/etc/ cd redis-4.0.6 cp redis.conf /usr/local/redis/etc/ vi redis.conf 将 daemonize no 改成 daemonize yes #设置密码授权 requirepass <设置密码>

1. 启动

cd redis-4.0.6/src ./redis-server /usr/local/redis/etc/redis.conf
