Mac無法啟動RocketMQ，日志顯示，runserver.sh: line 91: /Library/Internet: No such file or directory

前言

從日志的報錯信息可以看出, /Library/Internet 大概率是因為系統(tǒng)安裝的jdk路徑包含空格導(dǎo)致腳本啟動失敗

為什么能看出來是 jdk 路徑的問題, 那是因為遇到這種問題多了, 基本上也知道哪里會問題
特別是因為中間升級了 mac 的系統(tǒng), 那各種問題都有, 都想回退系統(tǒng)版本了

解決辦法

一. 改系統(tǒng)配置文件

1. 系統(tǒng)配置: /etc/profile

• 能改, 但對于高版本的 mac 系統(tǒng), 改了也生效不了, 除非一些特別的操作, 個人覺得風(fēng)險太大, 沒有繼續(xù)嘗試

2. 用戶配置: ~/.bash_profile

• 使用 vim 命令打開 ~/.bash_profile, 在文件最后, 添加如下內(nèi)容

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home
export PATH=$PATH:$JAVA_HOME/bin

• 讓改動生效(命令): source ~/.bash_profile

查詢自己mac安裝的各類jdk路徑
/usr/libexec/java_home -V

-bash-3.2$ /usr/libexec/java_home  -V
Matching Java Virtual Machines (5):
    13.0.2 (x86_64) "Oracle Corporation" - "Java SE 13.0.2" /Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home
    11.0.7 (x86_64) "Oracle Corporation" - "Java SE 11.0.7" /Library/Java/JavaVirtualMachines/jdk-11.0.7.jdk/Contents/Home
    1.8.301.09 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_301 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_301.jdk/Contents/Home
    1.8.0_221 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

二. 改啟動腳本

1. 指定腳本的jdk路徑

• 從報錯提示, 確實需要修改的啟動腳本: runserver.sh

• 使用命令 /usr/libexec/java_home -V 查詢當(dāng)前 mac 已安裝的 jdk 路徑

-bash-3.2$ /usr/libexec/java_home -V
Matching Java Virtual Machines (5):
    13.0.2 (x86_64) "Oracle Corporation" - "Java SE 13.0.2" /Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home
    11.0.7 (x86_64) "Oracle Corporation" - "Java SE 11.0.7" /Library/Java/JavaVirtualMachines/jdk-11.0.7.jdk/Contents/Home
    1.8.301.09 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_301 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_301.jdk/Contents/Home
    1.8.0_221 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

我選擇的版本是1.8
路徑是: /Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home

• 使用命令 vim {$path}/runserver.sh ({$path} 表示腳本所在的目錄/路徑 )

• 參考下面代碼, 將 export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home 添加到啟動腳本里

#===========================================================================================
# Java Environment Setting
#===========================================================================================
error_exit ()
{
    echo "ERROR: $1 !!"
    exit 1
}

[ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=$HOME/jdk/java
[ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=/usr/java
[ ! -e "$JAVA_HOME/bin/java" ] && error_exit "Please set the JAVA_HOME variable in your environment, We need java(x64)!"

# force set java_home
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home
# force set java_home

export JAVA="$JAVA_HOME/bin/java"
export BASE_DIR=$(dirname $0)/..
export CLASSPATH=.:${BASE_DIR}/conf:${CLASSPATH}

• 保存并退出 :wq , 重啟 RocketMQ 即可
