代码块注解

注意

1.代码中如果使用了grep 命令判断，不要使用 set -e，会报错，因为 set -e：遇到非0值直接退出代码，剩下的代码不在执行。
2.代码中如果想使用source /etc/init.d/functions，不要使用set -u会报错。两者冲突

代码变量设置

# 变量
URL=https://mirrors.tuna.tsinghua.edu.cn/apache//httpd/
FILE=httpd-2.4.46.tar.gz
INSTALL_DIR=/apps/httpd2
CPU=`lscpu | sed -rn ‘/^CPU\(s\)/s@.* ([0-9]+)@\1@p‘`
RESD="\E[$[RANDOM%7+31];1m"
END="\E[0m"

切割软件包

# 包名
PACKAGE=`echo $FILE |sed -nr ‘s/(.*[0-9.]+)\.[[:alpha:]]+.*/\1/p‘`
# 基名
BASEDIR=`basename $INSTALL_DIR`
# 后缀名
SUFFIX=`echo httpd-2.4.46.tar.bz2 |sed -nr ‘s/.*\.([^.]+)/\1/p‘`

需要的依赖包

cd /usr/local/src/
yum install -y gcc make apr-devel apr-util-devel pcre-devel openssl-devel redhat-rpm-config

关闭selinux和打开防火墙端口

sed -ri ‘s/^(SELINUX=).*/\1disabled/‘ /etc/sysconfig/selinux

#检查firewalld状态

firewall_status=`firewall-cmd --state`
if [ "$firewall_status" = "running" ];then
    echo "防火墙已启用，开放端口"
    firewall-cmd --permanent --add-service=http --add-service=https
    firewall-cmd --reload
fi

测试网络并下载包

ping -W1 -c 2 www.baidu.com &> /dev/null
if [ $? -eq 0 ]; then
    wget $URL$FILE
    case $SUFFIX in
    gz|bz2|xz|tar)
        tar -xvf $FILE
        ;;
    zip)
        unzip $FILE
        ;;
    *)
        echo "后缀识别不了，错误"
        exit 2
    esac
else
    echo -e  "\E[31m网络不通！！\E[0m"
    cp /root/$FLIE /usr/local/src/
fi

编译安装

cd $PACKAGE
./configure --prefix=$INSTALL_DIR --sysconfdir=/etc/$BASEDIR
make -j $CPU && make install

创建启动用户

grep -q apache /etc/passwd
if [ $? -eq 0 ];then
    echo "用户已经存在！"
else
    echo "没有用户，开始创建apache系统用户"
    sleep 5
    useradd -r -s /sbin/nologin -u 50 apache
fi

修改配置文件

sed -ri -e ‘s/^(User).*/\1 apache/‘ -e ‘s/^(Group).*/\1 apache/‘ /etc/$BASEDIR/httpd.conf
echo "PATH=$INSTALL_DIR/bin:$PATH" > /etc/profile.d/$BASEDIR.sh
source /etc/profile.d/$BASEDIR.sh
sed -ri ‘s#(^.*<h1>)(.*)(</h1>.*$)#\16.18 Go! \3 #‘ $INSTALL_DIR/htdocs/index.html

配置启动关闭system文件

cat > /lib/systemd/system/httpd.service <<EOF
