linuxtomcat啟動，linux tomcat守護_Linux 系統下 Tomcat 的服務配置和性能優化

近來發現很多 linux 系統管理員對 tomcat 系統服務的配置不是很規范，其實，Tomcat 自帶了一個守護進程管理工具 jsvc，可以用它來配置 Tomcat 的系統服務。

linuxtomcat啟動，為了演示的需要，我準備了 jdk 和 tomcat：

[root@RicenOS opt]# pwd

部署tomcat、/opt

[root@RicenOS opt]# ls

tomcat、java ? ?tomcat

進入到 tomcat 的 bin 目錄，解壓 commons-daemon-native.tar.gz：

[root@RicenOS opt]# cd tomcat/bin/

[root@RicenOS bin]# tar xvf commons-daemon-native.tar.gz

進入到解壓后的 unix 子目錄，配置并編譯：

[root@RicenOS bin]# cd commons-daemon-1.0.15-native-src/unix/

[root@RicenOS unix]# ./configure --with-java=/opt/java && make

把編譯生成的 jsvc 文件拷貝到 tomcat 的 bin 目錄下：

[root@RicenOS unix]# cp jsvc ../../

編寫服務腳本，把這個腳本放到 /etc/rc.d/init.d 目錄下：

[root@RicenOS unix]# vi /etc/rc.d/init.d/tomcat

內容參考如下：

#!/bin/sh

# chkconfig: 35 46 49

改變文件權限：

[root@RicenOS unix]# chmod +x /etc/rc.d/init.d/tomcat

配置系統啟動：

[root@RicenOS unix]# chkconfig --level 35 tomcat on

修改 tomcat/conf 目錄下的 server.xml 文件：

[root@RicenOS unix]# vi ../../../conf/server.xml

主要修改以下這段：

maxThreads="1000" minSpareThreads="100" maxSpareThreads="5000"

minProcessors="50" maxProcessors="500" enableLookups="false"

redirectPort="8443" acceptCount="1000" connectionTimeout="40000"

disableUploadTimeout="true" URIEncoding="utf-8" />
