tar -xzv -f jdk-8u152-linux-x64.tar.gz -C /opt/java/
ln -s /opt/java/jdk1.8.0_152 /usr/local/jdk

配置jdk环境变量

# 针对所有用户
vi /etc/profile
# 只针对当前用户
vi ~/.bashrc

vi /etc/profile.d/jdk.sh

nginx-1.13.9.tar.gz

# 创建目录
mkdir -p /opt/nginx/nginx-1.13.9

# 创建用户
id nginx
useradd nginx -s /sbin/nologin -M

# 安装pcre openssl
rpm -qa pcre pcre-devel
rpm -qa openssl openssl-devel
yum install pcre pcre-devel -y
yum install openssl openssl-devel -y

# 解压、编译安装
tar -xzvf nginx-1.13.9.tar.gz
cd nginx-1.13.9
./configure --user=nginx --group=nginx --prefix=/opt/nginx/nginx-1.13.9 --with-http_stub_status_module --with-http_ssl_module
make
make install

# chown -R nginx:nginx /opt/nginx/

ln -s /opt/nginx/nginx-1.13.9 /usr/local/nginx

#export TOMCAT_HOME=/usr/local/tomcat
#export CATALINA_HOME=/usr/local/tomcat
#export CATALINA_BASE=/usr/local/tomcat
#export CATALINA_TMPDIR=/usr/local/tomcat/temp

普通用户启动tomcat

# CATALINA_HOME=/usr/local/tomcat

cd $CATALINA_HOME/bin

# 解压commons-daemon-native.tar.gz
tar -xzvf commons-daemon-native.tar.gz
cd commons-daemon-native-src/unix

# 编译生成jsvc
./configure
make

# 将jsvc复制到$CATALINA_HOME/bin目录
cp jsvc $CATALINA_HOME/bin

# 添加一个tomcat用户
id tomcat
useradd tomcat -s /sbin/nologin -M

# 查看帮助
./daemon.sh -h

# 启动Tomcat
./daemon.sh start

# 查看进程
ps -aux | grep tomcat

设置权限

# 设置权限
cd /opt/tomcat
# 该目录归属为tomcat小组
sudo chgrp -R tomcat /opt/tomcat
cd apache-tomcat-8.5.28
# tomcat组对conf目录及其内容有读权限
sudo chmod -R g+r conf
# 对conf目录有执行权限
sudo chmod g+x conf
# 设置tomcat用户是webapps/, work/, temp/, logs/这几个目录的主人
sudo chown -R tomcat webapps/ work/ temp/ logs/
