  1. 一、nginx介绍：
  2.      可以作为一个HTTP服务器进行网站的发布处理，另外Nginx可以作为反向代理进行负载均衡的实现
  3.      nginx官网：
  4.      https://nginx.org/
  5.      nginx下载地址：
  6.      https://nginx.org/en/download.html
  7.      源码包地址：http://nginx.org/download/nginx-1.22.0.tar.gz
  8. 二、nginx版本：
  9.    源码安装包： nginx-1.22.0
# 1. 基础环境 
useradd -r -s /sbin/nologin -M www  ##创建nginx用户
yum install -y gcc gcc-c++ glibc glibc-devel pcre pcre-devel zlib zlib-devel openssl openssl-devel
# 2. 下载
wget -O https://nginx.org/download/nginx-1.22.0.tar.gz
# 3. 解压
tar -xf /work/packages/nginx-1.22.0.tar.gz
# 4. 编译安装nginx---#echo $?查看是否出错
cd /work/packages/nginx-1.22.0
./configure --prefix=/usr/local/nginx --user=www --with-http_stub_status_module --with-http_ssl_module
make && make install  
# 5. 设置systemd管理
ln -s /usr/local/nginx/sbin/* /sbin/
cp /work/config/nginx/nginx.service /usr/lib/systemd/system/

# 6. 配置nginx
\cp -f /work/config/nginx/nginx.conf /usr/local/nginx/conf/

mkdir -p /usr/local/nginx/conf/vhost/ && \cp -f /work/config/nginx/default.conf /usr/local/nginx/conf/vhost/

# 6. 启动nginx
systemctl enable --now nginx  

#7. 测试
ps -ef |grep nginx
ss -antl |grep :80

mkdir -p /data/{baidu,jd}
echo "nginx install successful" /data/baidu/index.html

zabbix

# server安装zabbix
# 1.获取zabbix源
rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#g' /etc/yum.repos.d/zabbix.repo
sed -i 's/enabled=0/enabled=1/' /etc/yum.repos.d/zabbix.repo
yum clean all 
yum makecache

# 2.安装zabbix客户端
yum -y install zabbix-server-mysql zabbix-agent2 


# 3.安装多个版本的软件工具，并且不会影响整个系统的依赖环境
yum -y install centos-release-scl

# 4.修改前端源，安装前端环境（并且安装到scl环境下）
或者http安装:yum -y install zabbix-web-mysql-scl zabbix-apache-conf-scl 

或者nginx安装:yum -y install zabbix-web-mysql-scl zabbix-nginx-conf-scl 


# 5.安装数据库,配置数据库开机启动,查看端口
yum -y install mariadb-server mariadb
systemctl enable --now mariadb
netstat -tunlp |grep 3306

# 6.初始化数据库
mysql_secure_installation   [回车--y--password--password--y--n--y--y]
mysql -uroot -p123

# 7.添加数据库用户授权
create database zabbix character set utf8 collate utf8_bin;
create user zabbix@% identified by 'password';
grant all privileges on zabbix.* to zabbix@localhost;
flush privileges;
exit;

# 8.使用zabbix-mysql导入数据库信息【-u用户名 -p 后面是数据库的库名字  然后才需要输入密码】
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

# 9.修改zabbix密码
vim /etc/zabbix/zabbix_server.conf 
DBPassword=password

# 10.修改php配置
vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
user = nginx
group = nginx
listen.acl_users = nginx 
php_value[date.timezone] = Asia/Shanghai

vim /etc/opt/rh/rh-php72/php.ini

393 max_input_time = 300

# 11.启动zabbix相关服务
     # http    systemctl restart zabbix-server zabbix-agent httpd rh-php72-php-fpm
yum -y intstall psmisc
killall nginx
     # nginx   systemctl restart zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm

#启动报错或Zabbix server is running    NO
1. 查看日志   tail -5 /var/log/zabbix/zabbix_server.log
2. 检查配置文件
3. 数据库授权问题(可能不让localhost登录)


# 12.访问zabbix入口
http://ip/zabbix
http://ip

# 13.zabbix默认用户密码
U：Admin
P：zabbix
# 同步时间
yum install ntpdate -y
ntpdate -u ntp.aliyun.com

# 14.时区的统一
mv /etc/localtime{,.bak}
ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

# 15.zabbix乱码问题  【zabbix-server安装中文字体】
yum -y install wqy-microhei-fonts
\cp /usr/share/fonts/wqy-microhei/wqy-microhei.ttc /usr/share/fonts/dejavu/DejaVuSans.ttf

java

一、环境配置：

    #1.1新建一个自定义目录用于存放下载或挂载
    mkdir /data/jdk
二、安装
    #2.1将软件包上传服务器并解压
    cd /data/
    tar -xf jdk-8u91-linux-x64.tar.gz
    #2.2移动解压后的文件夹(jdk1.8.0_91)到usr目录下并重命名（/usr/java）
    mv jdk1.8.0_91/ /usr/local/java
    #2.3配置环境变量 （vim /etc/profile）
cp /work/config/java/java.sh /etc/profile.d/
    #2.4重新生效环境变量配置文件
    source /etc/profile
    source /etc/profile.d/java.sh
三、测试
    #3.1使用java命令
    [root@mysql data]# java -version
    java version "1.8.0_91"
    Java(TM) SE Runtime Environment (build 1.8.0_91-b14)

export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JRE_HOME=$JAVA_HOME/jre

   开源的应用容器引擎，Docker 可以让开发者打包他们的应用以及依赖包到一个轻量级、可移植的容器
   中，然后发布到任何流行的 Linux 机器上，也可以实现虚拟化
二、安装
yum -y install docker
systemctl start docker
docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
