JDK

• SSH 登入伺服器

  cd /usr
  mkdir java
  cp /opt/jdk-8u161-linux-x64.tar.gz /usr/java/
  tar -zxvf jdk-8u161-linux-x64.tar.gz
  #建立短連結
  ln -s /usr/java/jdk1.8.0_161/ /usr/jdk

• 配置環境變數

  vi /etc/profile
  ​
  #新增以下內容
  JAVA_HOME=/usr/jdk
  CLASSPATH=$JAVA_HOME/lib/
  PATH=$PATH:$JAVA_HOME/bin
  export PATH JAVA_HOME CLASSPATH
  ​
  #立即重啟伺服器
  sudo shutdown -r
   
   now
  ​
  #重新登入伺服器
  java -version
  ​
  #看到如下內容配置成功
  java version "1.8.0_161"
  Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
  Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

NGINX

• yum 安裝

#YUM直接安裝
yum install nginx
​
#若出現以下提示 需新增 repo 源
沒有可用軟體包 nginx。
#新增 nginx 源
rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
 

#再執行安裝
yum install nginx

• 以下是Nginx的預設路徑：

  (1) Nginx配置路徑：/etc/nginx/

  (2) PID目錄：/var/run/nginx.pid

  (3) 錯誤日誌：/var/log/nginx/error.log

  (4) 訪問日誌：/var/log/nginx/access.log

  (5) 預設站點目錄：/usr/share/nginx/html

MYSQL

• 下載mysql源安裝包

  wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

• 安裝mysql源

  yum localinstall mysql57-community-release-el7-8.noarch.rpm
   
  

  ​

• 檢查mysql源是否安裝成功yum repolist enabled | grep "mysql.*-community.*"

  #如下則安裝源成功
  !mysql-connectors-community/x86_64 MySQL Connectors Community                 51
  !mysql-tools-community/x86_64      MySQL Tools Community                      63
  !mysql57-community/x86_64          MySQL 5.7 Community Server                267

• 可以修改vim /etc/yum.repos.d/mysql-community.repo源，改變預設安裝的mysql版本。比如要安裝5.6版本，將5.7源的enabled=1改成enabled=0。然後再將5.6源的enabled=0改成enabled=1即可

  ​

• 安裝mysqlyum install mysql-community-server

  ​

• 啟動systemctl start mysqld

• 檢視啟動狀態systemctl status mysqld顯示如下啟動成功

• 開機啟動

  systemctl enable mysqld
  systemctl daemon-reload

• 修改root本地登入密碼

  • mysql安裝完成之後，在/var/log/mysqld.log檔案中給root生成了一個預設密碼。通過下面的方式找到root預設密碼，然後登入mysql進行修改

  grep 'temporary password' /var/log/mysqld.log
  ​
  2018-04-19T12:17:44.562577Z 1 [Note] A temporary password is generated for [email protected]: fI;#Gle/N7Ey
  ​
  mysql -uroot -p
  ​
  ALTER USER 'root'@'localhost' IDENTIFIED BY '{newPassword}'; 
  #或者
  set password for 'root'@'localhost'=password('{newPassword}'); 

  • 注意：mysql5.7預設安裝了密碼安全檢查外掛（validate_password），預設密碼檢查策略要求密碼必須包含：大小寫字母、數字和特殊符號，並且長度不能少於8位。

• 新增遠端登入使用者

  GRANT ALL PRIVILEGES ON *.* TO '{userName}'@'%' IDENTIFIED BY '{userPassword}' WITH GRANT OPTION;
  FLUSH PRIVILEGES;

• 配置預設編碼 utf-8

  vi /etc/my.cnf
  #在[mysqld]下新增編碼配置，如下所示:
  ​
  [mysqld]
  character_set_server=utf8
  init_connect='SET NAMES utf8'

• 重新啟動mysql服務 service mysqld restart
