1、openjdk.org下载 openjdk22 tar.gz

不用jre

#vim /etc/profile

export JAVA_HOME=/usr/java/jdk

export JRE_HOME=$JAVA_HOME

export CLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib

export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

#source /etc/profile

2、tomcat11

tomcat.apache.org 下载tar.gz

不用 #vim /usr/local/tomcat/bin/setenv.sh

#vim /usr/loacal/tomcat/bin/catalina.sh

在 # OS specific support.  $var _must_ be set to either true or false. 添加

JAVA_HOME=/usr/java/jdk

JRE_HOME=$JAVA_HOME

#vim /lib/systemd/system/tomcat.service #ubuntu 18.04下

#vim /usr/lib/systemd/system/tomcat.service #ubuntu 22.04及以上

#systemctl enable tomcat.service

#systemctl start tomcat.service

3、nginx

----------------------------------------------

ubuntu22.04安装依赖(nginx 的 ssl pcre等)

1.首先使用dpkg命令查看自己需要的软件是否安装。

例如查看zlib是否安装：

dpkg -l | grep zlib

2.解决依赖包openssl安装，命令：

sudo apt-get install openssl libssl-dev

3.解决依赖包pcre安装，命令：

sudo apt-get install libpcre3 libpcre3-dev

4.解决依赖包zlib安装，命令：

sudo apt-get install zlib1g-dev 

.....................安装pcre..................

#wget https://sourceforge.net/projects/pcre/files/pcre/8.35/pcre-8.45.tar.gz

#tar -zxvf pcre-8.45.tar.gz

#cd pcre-8.45

#./configure  --prefix=/usr/local/pcre-8.45

#make && make install

-----------------------------------------------

#wget http://nginx.org/download/nginx-1.26.1.tar.gz && tar -zxvf nginx-1.26.1.tar.gz && cd nginx-1.26.1 && ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_sub_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_realip_module --with-pcre && make && make install

--with-pcre 使用系统pcre
 --with-pcre=/root/downloads/pcre-8.45 应该为源码的路径

#vim /usr/lib/systemd/system/nginx.service

或

#vim /lib/systemd/system/nginx.service #ubuntu 18.04

--------------------------------------
