--- tags: Dynasafe --- # Nexus 安裝 # Nexus ## 環境需求 * ### 作業系統: CentOS8 * ### JDK版本: 1.8以上 * ### Nexus版本: 3.33.1 * ### VM IP: 192.168.50.29 ## 安裝包 ### [官方載點](https://help.sonatype.com/repomanager3/download) ### ![](https://i.imgur.com/A78hWZE.png) ## 啟動步驟 ### 1. 複製安裝包到VM `/root` ![](https://i.imgur.com/wLmQR83.png) ### 2. 檢查 JDK 版本 ``` [root@localhost ~]java -version openjdk version "1.8.0_201" OpenJDK Runtime Enviroment (build 1.8.0_201-b09) OpenJDK 64-Bit Server VM (build 25.201-b09, mixed mode) ``` ### 3. 配置環境變數 ( 可忽略 ) ``` [root@localhost ~]vi /etc/profile export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el8_4.x86_64 export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export PATH=$PATH:$JAVA_HOME/bin --生效環境變數-- [root@localhost ~]source /etc/profile ``` ### 4. 創建資料夾 ( 放置nexus壓縮檔 ) ``` [root@localhost ~]mkdir /data/apps/nexus ``` ### 5. 解壓縮到剛剛創建的資料夾 ``` [root@localhost ~]tar -zxvf nexus-3.33.1-01-unix.tar.gz -C /data/apps/nexus ``` ### 6. 進入指定路徑 ``` [root@localhost ~]cd /data/apps/nexus/ [root@localhost nexus]ls nexus-3.33.1-01 sonatype-work ``` ### 7. 進入到執行檔 ``` [root@localhost nexus]cd nexus-3.33.1-01/bin/ [root@localhost bin]ls contrib nexus nexus.rc nexus.vmoptions ``` ### 8. 運行Nexus ``` [root@localhost bin]./nexus start WARNING: ************************************************************ WARNING: Detected execution as "root" user. This is NOT recommended! WARNING: ************************************************************ Starting nexus -- 運行狀態 -- [root@localhost bin]./nexus status WARNING: ************************************************************ WARNING: Detected execution as "root" user.

This is NOT recommended! WARNING: ************************************************************ Shutting down nexus Stopped. --重新啟動Nexus-- [root@localhost bin]./nexus restart ``` ### 9. 連線測試 ``` 連線到 http://[ ip ]:8081 ``` ### 10. Service Mode (non-root) #### 1. 創建 Nexus User ``` // create a system account // do not create the user's home directory // login shell of the new account $ useradd -r -M -s /sbin/nologin nexus ``` #### 2. 修改Nexus檔案 的 Group ``` // 路徑要為 Nexus檔案路徑 $ chown nexus:nexus -R /data ``` #### 3. Create nexus.service ``` $ vi /etc/systemd/system/nexus.service ... [Unit] Description=nexus service After=network.target [Service] Type=forking LimitNOFILE=65536 =========> Nexus 最低要求 ExecStart=/data/apps/nexus/nexus-3.33.1-01/bin/nexus start =========> Nexus 檔案路徑 ExecStop=/data/apps/nexus/nexus-3.33.1-01/bin/nexus stop =========> Nexus 檔案路徑 User=nexus =========> 剛剛創建的使用者名稱 Restart=on-abort TimeoutSec=600 [Install] WantedBy=multi-user.target ``` #### 4. 修改啟動Nexus的使用者 ``` vi /data/nexus/nexus-3.33.1-01/bin/nexus.rc ... run_as_user="nexus" ``` #### 5. 啟動 nexus.service ``` $ systemctl daemon-reload $ systemctl enable nexus.service $ systemctl start nexus.service ``` #### 6. 測試 stop nexus.service 是否有錯誤 ``` // 會發現 有錯誤 $ systemctl status nexus.service ... Active: failed (Result: exit-code) since Fri 2021-08-27 11:31:17 CST; 2min 4s ago ... // 這是因為在 /data 底下的檔案 有些Group還是 root $ ls -lR /data/ | grep root -rw-r--r-- 1 root root 6560 Aug 27 11:27 cache.stt

### • 無 JDK 1. #### 掛載 iso 2. #### Mount RHEL CD and set yum repository 1. ##### 列出系統上的所有磁碟列表 ``` $ lsblk -fp ``` ![](https://i.imgur.com/UoWXP65.png) 2. ##### 掛載磁碟 ``` $ mount -t [ FSTYPE ] [ 磁碟NAME ] [ 掛載點 ] $ mount -t iso9660 /dev/sr0 /mnt $ lsblk -fp ``` ![](https://i.imgur.com/ylGeWNn.png) 3. ##### 查看掛載的詳細檔案 ``` $ ls /mnt // 主要使用 AppStream、BaseOS ``` ![](https://i.imgur.com/oqfO5MN.png) 4. ##### 撰寫 repo檔 ``` $ vi /etc/yum.repo.d/AppStream.repo [AppStream] name=DVD for Red Hat Enterprise Linux 7.9 Server gpgcheck=0 enabled=1 baseurl=file:///mnt/AppStream/ $ vi /etc/yum.repos.d/BaseOS.repo [BaseOS] name=DVD for Red Hat Enterprise Linux 7.9 Server gpgcheck=0 enabled=1 baseurl=file:///mnt/BaseOS/ ``` 5. ##### 查詢 JDK ``` $ yum search java | grep jdk ``` 6. ##### 下載 JDK ``` $ yum install java-1.8.0-openjdk.x86_64 ``` ### • 無法連線 #### 排解1. 查詢Port是否監聽 ``` $ sudo netstat -anopt Active Internet connections (servers and established) Proto Recv-Q Send-Q Local
