以下是在工作當中積累下來的linux常用命令，以做不時之需。
-------------------------------------------------------------- Tomcat -------------------------------------------------------
Tomcat 常用命令
netstat -ap |grep 8080 //查找tomcat端口是否被占用
tail -f catalina.out 查看日志
jar -xvf project.war 解壓war包
first off, i check maven central via search.maven.org. recall that maven central is defined in the super pom and, if i find it in here, i won't need to add any extra repository information to my pom or settings file. i enter flexunit into the search box and it yields the three items shown in figure 2:。 xsi:schemalocation="http://maven.apache.org/pom/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">。 xsi:schemalocation="http://maven.apache.org/pom/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">。
maven環(huán)境變量配置：打開/etc/profile，在文件最后添加
export MAVEN_HOME=/usr/local/java/maven3.5
export MAVEN_HOME
export PATH=$PATH:$MAVEN_HOME/bin
---------------------------------------------------------------- nginx -------------------------------------------------------
Nginx常用命令:
啟動：
/usr/local/nginx/sbin
./nginx
重啟:
/usr/local/nginx/sbin
./nginx -s reload
判斷配置文件是否正確:
cd /usr/local/nginx/sbin
./nginx -t
看到如下顯示 說明配置文件正確！
nginx.conf syntax is ok
nginx.conf test is successful
查詢nginx主進程號
ps -ef | grep nginx
