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

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 

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

一、jre1.8 wget http://download.oracle.com/otn-pub/java/jdk/8u144-b01/090f390dda5b47b9b721c7dfaa008135/server-jre-8u144-linux-x64.tar.gz

#tar -zxvf server-jre-8u144-linux-x64.tar.gz

#mkdir /usr/java

#mv jdk1.8.0_144 /usr/java/

#chown root:root -R /usr/java/jdk1.8.0_144/

#vi /etc/profile

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

export JAVA_HOME=/usr/java/jdk1.8.0_144

export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib

export PATH=$JAVA_HOME/bin:/usr/local/nginx/sbin:/usr/local/mysql/bin:$PATH

---------------------- 

#source /etc/profile

测试# java -version

java version "1.8.0_131"

#以及java和javac命令都行

chmod 777 *.sh

 cd /usr/java/jdk1.8.0_144/jre/lib/security/【修改后，tomcat启动速度快了】
 vi java.security
 编辑这个文件
 将 securerandom.source=file:/dev/urandom
 修改为 securerandom.source=file:/dev/./urandom

二、tomcat9 wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.0.M26/bin/apache-tomcat-9.0.0.M26.tar.gz

#tar -zxvf apache-tomcat-9.0.0.M26.tar.gz

#mv apache-tomcat-9.0.0.M26 /usr/local/tomcat

#vi /etc/profile 【可不要】

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

# begin - tomcat9

CATALINA_HOME=/usr/local/tomcat

CATALINA_BASE=/usr/local/tomcat

PATH=$PATH:$CATALINA_BASE/bin

export PATH CATALINA_BASE

# end - tomcat9

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

#source /etc/profile

#vi /usr/local/tomcat/conf/server.xml 【修改server.xml】

#vi /usr/local/tomcat/bin/catalina.sh

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

在 # OS specific support. 前面【修改】加入如下代码：

  JAVA_HOME=/usr/java/jdk1.8.0_144

  JRE_HOME=$JAVA_HOME/jre

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

#自启动

tomcat需要增加一个pid文件

在tomcat/bin 目录下面，增加setenv.sh配置，catalina.sh启动的时候会调用，同时配置java内存参数

# vim setenv.sh

写入一下命令：

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

#tomcat启动pid

export CATALINA_HOME=/usr/local/tomcat

export CATALINA_BASE=/usr/local/tomcat

#add tomcat pid

CATALINA_PID="$CATALINA_BASE/tomcat.pid"

#add java opts

JAVA_OPTS="-server -XX:PermSize=256M -XX:MaxPermSize=1024m -Xms512M -Xmx1024M -XX:MaxNewSize=256m"

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

chmod 777 *.sh

3、增加tomcat.service

在/usr/lib/systemd/system目录下增加tomcat.service，目录必须是绝对目录

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

写入一下命令:

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

[Unit]

Description=Tomcat

After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]

Type=forking

PIDFile=/usr/local/tomcat/tomcat.pid

ExecStart=/usr/local/tomcat/bin/startup.sh

ExecReload=/bin/kill -s HUP $MAINPID

ExecStop=/bin/kill -s QUIT $MAINPID

PrivateTmp=true

[Install]

WantedBy=multi-user.target

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

#chmod 754 /usr/lib/systemd/system/tomcat.service

#systemctl enable tomcat.service

#systemctl start tomcat.service

#firewall-cmd --zone=public --add-port=8080/tcp【添加防火墙 没有 --permanent 重启失效】

#firewall-cmd --reload

三、nginx wget http://nginx.org/download/nginx-1.13.4.tar.gz

#tar -zxvf nginx-1.13.4.tar.gz

#cd nginx-1.13.4

创建nginx用户www

#groupadd www

#useradd -g www www

#./configure --user=www --group=www --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=../pcre-8.32

#make && make install

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

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

[Unit]

Description=nginx - high performance web server

After=network.target remote-fs.target nss-lookup.target

[Service]

Type=forking

ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

ExecReload=/usr/local/nginx/sbin/nginx -s reload

ExecStop=/usr/local/nginx/sbin/nginx -s stop

[Install]

WantedBy=multi-user.target

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

#chmod 754 /usr/lib/systemd/system/nginx.service

systemctl enable nginx.service

systemctl start nginx.service

firewall-cmd --zone=public --add-port=80/tcp --permanent#【添加防火墙 没有 --permanent 重启失效】

firewall-cmd --reload
