私服建设（一）搭建

下载Nexus 网址：http://www.sonatype.org
解压文件nexus-2.6.4-02
修改配置文件：nexus-2.6.4-02\bin\jsw\conf\wrapper.conf

# Set the JVM executable
# (modify this to absolute path if you need a Java that is not on the OS path)
wrapper.java.command=java

# Set the JVM executable
# (modify this to absolute path if you need a Java that is not on the OS path)
wrapper.java.command=C:\Program Files\Java\jdk1.6.0_45\bin\java

可以执行启动命令：nexus-2.6.4-02\bin\nexus start
报错：

wrapper | OpenSCManager failed - 拒绝访问。（0x5）

查找原因 ：http://blog.csdn.net/ybw2011/article/details/7690710

runas /user:administrator cmd
输入密码，出现窗口再次执行命令，又出现错误
wrapper  | The nexus-webapp service is not installed - 指定的服务未安装。 (0x424)
查找原因：没有安装
所以先执行 ：nexus install
再执行启动： nexus start

nexus install
wrapper  | nexus installed.
nexus start
E:\nexus-2.6.4-02\bin>nexus start
wrapper  | Starting the nexus service...
wrapper  | Waiting to start...
wrapper  | Waiting to start...
wrapper  | Waiting to start...
wrapper  | The nexus service was launched, but failed to start.

看不到错误，查看配置文件，发现有log配置
打开配置日志：

# ********************************************************************
# Wrapper Logging Properties
# ********************************************************************
# Enables Debug output from the Wrapper.
#wrapper.debug=TRUE

# Format of output for the console.  (See docs for formats)
wrapper.console.format=PM

# Log Level for console output.  (See docs for log levels)
wrapper.console.loglevel=INFO

# Log file to use for wrapper output logging.
wrapper.logfile=../logs/wrapper.log

# Format of output for the log file.  (See docs for formats)
wrapper.logfile.format=LPTM

# Log Level for log file output.  (See docs for log levels)
wrapper.logfile.loglevel=INFO

# Maximum size that the log file will be allowed to grow to before
#  the log is rolled. Size is specified in bytes.  The default value
#  of 0, disables log rolling.  May abbreviate with the 'k' (kb) or
#  'm' (mb) suffix.  For example: 10m = 10 megabytes.
#wrapper.logfile.maxsize=0

# Maximum number of rolled log files which will be allowed before old
#  files are deleted.  The default value of 0 implies no limit.
#wrapper.logfile.maxfiles=0

# Log Level for sys/event log output.  (See docs for log levels)
#wrapper.syslog.loglevel=NONE

再次启动，同样的错误停止，找到日志位置查看日志

升级JVM版本到1.7

# Set the JVM executable
# (modify this to absolute path if you need a Java that is not on the OS path)
wrapper.java.command=C:\Program Files\Java\jdk1.7.0_45\bin\java

再次启动服务

E:\nexus-2.6.4-02\bin>nexus start
wrapper  | Starting the nexus service...
wrapper  | Waiting to start...
wrapper  | Waiting to start...
wrapper  | Waiting to start...
wrapper  | Waiting to start...

好像是没有问题了，试一下网址：http://localhost:8081/nexus/index.html#welcome
好了出现主界面。点击右上角login 用 admin/admin123 进行登录，左边菜单树有变化了，基本安装完成了！
