Confluence 提高Java虚拟机内存
版本
系统：CentOS release 6.8 (Final)
Java版本：1.8.0_162
Confluence版本：6.8.5
问题描述
confluence内存使用率的配置都是默认的，相对会比较低，可以根据实际server的配置情况，升级内存。

Linux 提高内存步骤
进入到${confluence}/bin目录下(默认/opt/atlassian/confluence/bin)，修改setenv.sh文件
[root@node1 ~]# cd /opt/atlassian/confluence/bin
[root@node1 bin]# cp -a setenv.sh{,_$(date +%F)}
[root@node1 bin]# ll setenv.*
-rw-r--r-- 1 root root 2553 7月 11 04:13 setenv.bat
-rwxr-xr-x 1 root root 3034 11月 26 11:40 setenv.sh
-rwxr-xr-x 1 root root 3034 11月 26 11:40 setenv.sh_2018-11-26
[root@node1 bin]# vim setenv.sh

69 CATALINA_OPTS="-Xms1024m -Xmx1024m -XX:+UseG1GC ${CATALINA_OPTS}"
70 CATALINA_OPTS="-Dsynchrony.enable.xhr.fallback=true ${CATALINA_OPTS}"
71 CATALINA_OPTS="-Dorg.apache.tomcat.websocket.DEFAULT_BUFFER_SIZE=32768 ${CATALINA_OPTS}"
72 CATALINA_OPTS="${START_CONFLUENCE_JAVA_OPTS} ${CATALINA_OPTS}"
73 CATALINA_OPTS="-Dconfluence.context.path=${CONFLUENCE_CONTEXT_PATH} ${CATALINA_OPTS}"
74 CATALINA_OPTS="-XX:ReservedCodeCacheSize=256m -XX:+UseCodeCacheFlushing ${CATALINA_OPTS}"
75
76
77 export CATALINA_OPTS
把69行的-Xmx1024m参数改为自己要求的最大内存，例如：-Xmx3072m
69 CATALINA_OPTS="-Xms1024m -Xmx3072m -XX:+UseG1GC ${CATALINA_OPTS}"重启 confluence(需要管理员权限)
# 关闭服务
service confluence stop
# 启动服务
service confluence start 查看confluence内存配置是否生效。

进入到${confluence}\bin目录下(默认C:\Atlassian\Confluence\bin)，修改setenv.bat文件

进入到服务管理的界面（我的电脑->右键->管理->服务=====或者=====services.msc）找到confluence的服务，在这里启动关闭服务。
